把里轉換兀件組13〇係包含有多個光電轉換元件或熱電轉換 元件’前述之多個能量轉換元件係對光線(光能量)具有不同的吸收 頻譜峰值。在本實施例中，能量轉換元雜no係包含三個能量 8 201230369 轉換元件131、132、133，且能量轉換元件131、132、133具有不 同的吸收波段(吸收頻譜峰值）。此些能量轉換元件131、132、133 側邊相鄰地設置，各個能量轉換元件132/133的吸收波段可接續相 鄰配置的前一能量轉換元件131/132的吸收波段，即能量轉換元件 131、132、133的吸收波段不重疊。能量轉換元件組係設置於 集光元件112的集光面A上’且能量轉換元件組13〇的收光面i3〇a (即各能量轉換元件13卜132、133之收光面i3〇a)面向集光元 件112，使集光後的光線能入射至能量轉換元件131、132、133 中。要說的是，在此雖列舉能量轉換元件組13〇之能量轉換元件 13卜132、133側邊相鄰設置為例，但並不以此為限，只要能量轉 換元件組130設置在集光元件112的集光面a上，使集光後的光 線能入射至能量轉換元件組13〇中即可。此外，集光面A可與集 光元件112的光軸L形成一夾角。此夾角可介於6〇度到12〇度之 間。在-實施射，集光面A可大致上㈣於錢元件m的光 轴L。 依本實施例’域統過光柵114及㈣錯112後會形成 具有5波段之多個縣，光束在觀面A上形成聚光斑， 而各此里轉換7G件⑶、132、133則依其魏光譜峰值對應配置 於各光束所形成之聚光斑位置，因此，能量轉換元件i3i、132、 133另-列舉配置方式岐將各能量轉換元件丨3卜说、⑶收光 面l3〇a的中〜軸(即為其垂直入射之軸)對應於各光束之光軸，意

入到光栅114，將入射的太陽光1〇2分光為三個不同波長的光束， 並經由人射面112b人射至集光元件112，分光後的縣於集光元 件112集光後，會經由出射面U2a的絲，而在集光面a上依不 同波長（λ] λ:和h)集光到不同的聚光斑上。能量轉換元件組 130中的能量轉換元件13卜132、133係設置在這些聚光斑上。詳 201230369 細來說’各能量轉換元件131、132、133設置在其相對應吸收頻 譜峰值之不同波段光束的聚光斑上。即，能量轉換元件131、132、 133的吸收頻譜峰值會相應於形成其設置處上之聚光斑的光的波 長（λ]、λ2和λ;)。換言之，能量轉換元件13卜132、133的吸收 波丰又會包含對應之波長（\、χ2或χ3)。或者是，對應之波長（入】、 λ2或係位於能量轉換元件131、132或133的吸收頻譜的中央。 於此’集光元件112可致使太陽光1〇2 (即入射光源）在集光 後以小角度的入射角入射至各個能量轉換元件131、132、133。在 一實施例中，此入射角可介於_3〇度到3〇度之間。此處的入射角 係指入射之光束與能量轉換元件131、132、133收光面13〇a的法 線之間的爽角。 請參考「第4圖」’與「第3圖」之實施例不同之處在於， 本實施例所制的集光元件112為平凸透鏡。同樣地，當太陽光 102進入到多波段集光及能量轉換模組1〇〇時，會先經過多波段集 光器110 ’經由多波段集光器110的分光與集光後，形成多個不同 波段的光束入射到能量轉換元件組13〇。 請參考「第5圖」，與「第3圖」、「第4圖」之實施例不 同之處在於，本實施例所採用的集光元件112為菲涅爾透鏡 (Fresnel lens)。在一實施例中，菲涅爾透鏡可使用二維集光式菲 /圼爾透鏡。此外，菲涅爾透鏡也可為一維集光式。同樣地，當太 陽光102進入到多波段集光及能量轉換模組刚日_，會先經過多 波段集光器110,經由多波段集絲⑽的分錢集絲，形成多 個不同波段的光束入射到能量轉換元件組丨3〇。 201230369 。月參考第6圖」’與「第3圖」之實施例不同之處在於， 本實施例中之光栅114係設置於集光元件丨12的出射面丨Ua上。 因此，當太陽光102進入到多波段集光器n 面⑽入射至槪㈣，並峨州曝ί.，=

b ^例所採用的集光元件112為平凸透鏡。由於光栅U4設置 於集光元件112的出射面112a (即平凸透鏡的平面）上，因此， 在本實施例中，所使用的光柵可為等週期光柵，即光栅m 投影辦凸透鏡巾的曲面之域TL㈣期（間距（piteh))均相 等。而「第6圖」之實施例，光栅114設置於集光元件⑴的出 、、仏（即雙凸透鏡的凸面）上，所使用的光栅μ亦可為等 週期光柵，即光栅114投影到雙凸透鏡之切線几的獅（間距） 均相等。要說的是，在此僅列舉光栅114投影到切'線TL的週期可 2週期之設計’熟習本領域技藝者當知光柵m之週期可有不 同設計之變化’並不以所列舉者為限。 帛8圖」’圖不係為一反射式的多波段集光及能量 換祕組100，與前述實施例所不同的是，太陽光1〇2是來自於相 201230369 對應於能量轉換元件組130之收光面i30a背面方向入光（進入多 波段集光器110)，而非如前述實施例之太陽光1〇2由能量轉換元 件組130之收光面i30a方向入光。因此，在本實施例中，採用的 集光兀件112可為反射式集光透鏡，其中可於集光元件112之出 射面112a或入射面U2b形成反射面，且光栅114形成於集光元 件112之出射面112&上。當太陽光1〇2進入到多波段集光器11〇 恰，先經由光柵114的分光後，進入到集光元件112中進行集光， 由於出射面112a或入射面i12b為反射面，因此分光後的光束會 在集光元件112中反射，並集光在集光面a上，再進入到位於集 光面A的能量轉換元件組13〇。在另一實施例中，多波段集光器 110可一體成型，即集光元件112與光栅為一體，此時，可在 光柵m的表面上設置反射層，例如是塗布金屬。當太陽光搬 進入到多波段集光器110時，會直接在光栅114中反射、集光與 分光，同樣使得光源集光在集光面八上。 多波段集光及能量轉換模、组100在實際的設計上，舉例來說， 可參照「第9圖」’於此採用雙凸透鏡作為集光元件ιΐ2，光棚ιΐ4 可設計成將入射光依照波長分光為λ]、^的三波段光，盆 中又产鄕麵、又2=__以及A3=7〇〇nm，其相對應設置在集

此外’參照「第10圖」，光柵114可由二個以上的次光柵115、 出所構成。此些次光栅115、116可交錯排列。再者，此些次光 栅115、116可具有相同週期，亦可具有不同週期，可依實際需求 而有不同的設計。於此，各個次光栅115 ' 116可將入射光源在集 光面A上形成各自的次聚纽，以致於透過次聚光_疊加來得 到-中心平坦的總聚光斑，進而避免能量過度集中。換言之，對

Description of the invention: [Technical field to which the invention pertains] This proposal relates to a collection and collection of energy and energy, in particular, a module capable of collecting too much or other light depending on its wavelength and performing energy conversion. [Prior Art] There are many solar cell technologies today, but there is currently no solar cell's absorption spectrum that fully matches the sunlight's luminescence spectrum. This "figure 1" is the illuminating spectrum of sunlight (AM 1.5G). "Figure 2 shows three kinds of corrections. (4) The sunlight has a non-wei spectrum. θ refers to "1st and 2nd maps". Most solar cells can only absorb some special wavelengths of sunlight. Therefore, in the existing solar cell technology, the solar photo-energy method is effectively utilized, and multi-band solar absorption technology is required to more effectively utilize solar energy of different wavelength bands. Traditional multi-band solar absorption technology relies on vertical stacking technology, that is, tandem solar cells (tandem. Cascading eclipse money is to stack two or three different solar cells in the vertical direction to increase The absorption spectrum of a solar cell. However, the material itself (IV), the lower the amount of light passing through the phase phase material layer, thus reducing its light absorption. And the domain energy battery with different absorption spectra has a non-lattice constant (lattice. The grid constant material has some defects in the junction, thus affecting its photocurrent collection. Therefore, stacking a layer of material 'to reduce the resistance value at the junction' while solving the problem of lattice constant mismatch, 4 201230369 Ren is # relatively increased the cost and complexity of production. In the vertical stacking technology, two solar cells and four solar cells can be piled up, but as the number of stacked layers increases, the production of shouts and retracements The increase is not necessarily linear, and the yield of the process is not affected. The ratio of the light is the light-receiving area of the light-collecting H to the light-receiving area of the solar cell placed on the spot. When there is a higher collecting light_solar energy system, the solar cell material used will be less. Technically, the arched-turn lens (archedF coffee) ί sunlight collects light on the solar cell to increase the strength of the county and reduce the use of solar energy. However, the absorption spectrum of the solar cell is different from the sunlight. The spectrum, unabsorbed solar energy is converted into heat, _ increases the temperature of the solar cell substrate, thus reducing the solar cell _ change efficiency. Therefore, the heat sink is additionally designed. However, the heat sink design increases the solar power system. The cost and complexity of the other. In the other technology, the design of the off-axis Philippine lens is used. According to the design principle of the off-axis Phillip lens, different wavelengths will be due to the high dispersion material. Hiding, and collecting light in different positions on the light human (4) (10) Qn. Then, placing the non-domain energy battery near the axial direction of the light, making different waves It is not _ solar battery Wei. But such a design will cause the incident light to have a large consumption rate, and the high dispersion material has a problem that is difficult to obtain. Related technologies and research can refer to US Patent No. 6,281,426, 5, Liu, No. 201230369 and No. 4,204,881, etc. [Summary of the Invention] In view of the above problems, the main purpose of this proposal is to provide a multi-band concentrating and energy-reducing group. The multi-band concentrating and energy conversion module disclosed in the proposal includes a multi-band concentrator and an energy conversion component group. The multi-band concentrator comprises a grating and a light collecting component. The grating position is on the surface of the subtracting component. The conversion element group includes a plurality of variable elements. The side units of the energy conversion elements are disposed on the county plane of the light collecting element, and the light collecting surface of the (four) changing element faces the light collecting element. This proposal also proposes a multi-band concentrating and energy conversion module comprising a multi-band concentrating H-and-energy conversion element set. The township band collecting system separates and collects the human light source according to the wavelength, and includes a grating and a light collecting element. The grating splits the incident source by wavelength. The light collecting element can collect the incident light source on a light collecting surface. The energy conversion element group includes a plurality of energy conversion elements disposed on a light collecting surface of the light collecting element, and a light collecting surface of the energy conversion element group faces the light collecting element. Wherein, after the incident light source is split and collected by the multi-band concentrator, a plurality of light beams forming different wavelength bands are incident on the energy conversion element group.

Also, the use of multi-band concentrators t ^ low energy conversion element material usage. In addition, the collected sunlight or j light can be used to reduce the reflectivity of sunlight or other light. The description of the contents of this (4) and the following description of the implementation of the proposal is not to explain the spirit and principle of this proposal, and to provide a more advanced explanation of the scope of the patent application of this proposal. [Embodiment] In this proposal, a multi-band concentrator is used to take a light source of different wavelengths such as sunlight or other light, and reduce it to a different position in the lateral direction of the light beam to form a different one. The spot light of the different wavelength bands may refer to a wavelength range of not 5, frequency: day range or a specific light wavelength. Hereinafter, for convenience of explanation, sunlight will be used _ 'but this proposal is not limited thereto, and may be Ambient light or other light. Next, a corresponding energy conversion element is disposed on each of the condensing spots. Here, the summer conversion element may be, but not limited to, a photoelectric conversion element or a thermoelectric conversion element. It may be that the absorption spectrum bee value of the aforementioned energy conversion element corresponds to the wavelength band (wavelength) of the beam of the concentrated spot (note: the energy conversion element has the same and the peak of the spectrum of the sunlight), for example, if the energy conversion If the component absorption spectrum value 201230369 is 500 nm (four), it can be placed in the light band of the beam to cover the spot of the peak. So, each energy conversion component can have Good conversion efficiency, and thus improved seam conversion efficiency, can reduce the occurrence of ugliness. Therefore, since multi-band f-light H has county touch, it can improve the collection ratio of the township band concentrator and reduce it. The usage rate of the material of the energy conversion element. The "3rd picture" is the unintentional control of the multi-band subtraction energy conversion module according to the present seam. The multi-band concentrating and energy conversion module includes a multi-band concentrator (10) and a summer conversion 70-piece set 130. The multi-band 11G system includes a grating H4 and a light collecting element 112. The grating 114 is located on the surface of the light collecting element 112. The light collecting element 112 of the multi-wavelength concentrator 110 emits light onto the light collecting surface A. The grating m is used to illuminate a person's beam by the light beam of the new section nG to form a plurality of beams. For example, the incident sunlight 1 〇 2 can be divided into three-band beams according to different wavelengths V W & Although the three-band beam is a specific wavelength, for example, the sub-band is not limited thereto. It may also be a band beam of three different wavelength ranges, for example, a beam of two wavelengths of 1 2# λ3^ towel~wavelength. As for the multi-band _ second system, the sun light temple is divided into light, and then the light is collected, or the light is collected and then split; this is the purpose of this proposal. In this embodiment, the light is collected first and then collected. In the present embodiment, the concentrating surface 示意 is illustrated in a planar manner, but it is not limited thereto. The concentrating surface A may also be changed according to the concentrating characteristics of the concentrating element ι ΐ 2, for example, a curved surface or Continue to connect multiple segments. The inner switching element group 13 includes a plurality of photoelectric conversion elements or thermoelectric conversion elements. The plurality of energy conversion elements described above have different absorption spectrum peaks for light (light energy). In the present embodiment, the energy conversion element contains three energy 8 201230369 conversion elements 131, 132, 133, and the energy conversion elements 131, 132, 133 have different absorption bands (absorption spectrum peaks). The energy conversion elements 131, 132, 133 are disposed adjacent to each other, and the absorption band of each of the energy conversion elements 132/133 can continue to absorb the absorption band of the adjacent energy conversion elements 131/132, that is, the energy conversion element 131. The absorption bands of 132 and 133 do not overlap. The energy conversion element group is disposed on the light collecting surface A of the light collecting element 112 and the light receiving surface i3〇a of the energy conversion element group 13〇 (ie, the light receiving surface i3〇a of each of the energy conversion elements 13 and 132, 133) The light collecting element 112 faces the light collecting elements 131, 132, and 133 so as to be incident on the light converting elements 131, 132, and 133. It is to be noted that although the side of the energy conversion element 13 132, 133 of the energy conversion element group 13 is adjacently disposed as an example, it is not limited thereto, as long as the energy conversion element group 130 is disposed in the light collection. On the light collecting surface a of the element 112, the collected light can be incident on the energy conversion element group 13A. Further, the light collecting surface A may form an angle with the optical axis L of the light collecting element 112. This angle can range from 6 to 12 degrees. The light-emitting surface A can be substantially (four) on the optical axis L of the money element m. According to the embodiment, the domain is integrated with the grating 114 and the (four) error 112, and a plurality of counties having five bands are formed, and the light beam forms a spot on the viewing surface A, and the 7G pieces (3), 132, and 133 are converted therein. The peaks of the Wei spectrum are arranged corresponding to the positions of the collecting spots formed by the respective light beams. Therefore, the energy conversion elements i3i, 132, and 133 are arranged in the same manner as the energy conversion elements 丨3 and (3) the light receiving surface l3〇a. The ~ axis (i.e., the axis for which it is normally incident) corresponds to the optical axis of each beam, that is, the energy conversion elements 131, 132, ! The angle of loss between the central axis of the material plane 13〇a and the optical axis L of the corresponding beam is between 2 degrees (or between 16 degrees and 201230369 degrees). , step by step to improve energy conversion efficiency. The concentrating read m system includes an exit surface 112a and an incident surface that wins and receives the incident light source, and collects the light through the convection. The exit surface of the light collecting element 112 must be sized to cover the light collecting surface of the energy group 13〇. In the case of performing the radiation, the energy conversion illusion 30 may be less than or equal to the dichotomy of the width D of the light collecting element m. In another embodiment, the light-receiving surface of the energy conversion element group 13〇! The system is less than or equal to one-half of the area of the unit 112 such as 12a vertical on the slope. The grating 114 is bonded or fabricated on the touch surface of the county element u2. In other words, the light collecting element 112 and the grating 114 can be separate two elements, or a single body formed. For example, "帛3 Stomach" is not attached to the incident surface 112b of the light collecting element 112. In addition, the light collecting element m may be a lens, and the light source element 112 is a lenticular lens, but is not limited thereto. When the sunlight 102 enters the multi-band concentrating and energy conversion module 1 ,, it will pass through the New County silk (10), and the beam splitting of the multi-wave ϋ no ϋ no To the energy conversion component ancestor]%. In the example of "Fig. 3", when the sunlight 1〇2 passes through the multi-band concentrator, it first enters the grating 114, and splits the incident sunlight into two beams of three different wavelengths. And passing through the human face 112b to the light collecting element 112, the light-distributed county collects light from the light collecting element 112, and then passes through the wire of the exit surface U2a, and the different wavelengths (λ) λ on the light collecting surface a: And h) collecting light onto different spotlights. The energy conversion elements 13 132, 133 in the energy conversion element group 130 are disposed on these condensing spots. DETAILED 201230369 In detail, each of the energy conversion elements 131, 132, 133 is disposed on a spot of a beam of a different wavelength band corresponding to the peak of its corresponding absorption spectrum. That is, the absorption spectrum peaks of the energy conversion elements 131, 132, 133 correspond to the wavelengths (λ], λ2, and λ of the light forming the focused spot on the place where they are disposed; In other words, the absorption wavelength of the energy conversion elements 13 132, 133 will in turn contain the corresponding wavelength (\, χ 2 or χ 3). Alternatively, the corresponding wavelength (in), λ2 or is located in the center of the absorption spectrum of the energy conversion element 131, 132 or 133. Here, the 'light collecting element 112 can cause the sunlight 1 〇 2 (ie, the incident light source) to be concentrated. Then incident on each of the energy conversion elements 131, 132, 133 at a small angle of incidence. In an embodiment, the angle of incidence may be between _3 to 3 degrees. The angle of incidence here is incident. The angle between the beam and the normal of the light-receiving elements 131, 132, and 133 of the light-receiving surface 13a is the difference between the embodiment of "Fig. 4" and "Fig. 3". The concentrating element 112 produced by the example is a plano-convex lens. Similarly, when the sunlight 102 enters the multi-band concentrating and energy conversion module 1 ,, the multi-band concentrator 110 ' passes through the multi-band concentrating light first. After splitting and collecting light of the device 110, a plurality of light beams of different wavelength bands are formed and incident on the energy conversion element group 13A. Please refer to "figure 5", which is different from the embodiments of "Fig. 3" and "4th figure". The light collecting element 112 used in this embodiment is a Fresnel lens (Fresnel lens). In an embodiment, the Fresnel lens can use a two-dimensional concentrating phenanthrene lens. In addition, the Fresnel lens can also be a one-dimensional concentrating type. Similarly, when the sunlight 102 enters more The band concentrating and energy conversion module will first pass through the multi-band concentrator 110, and a plurality of different wavelength bands of light beams are incident on the energy conversion element group through the multi-band collection wire (10). 201230369. The reference to Fig. 6 is different from the embodiment of Fig. 3 in that the grating 114 in this embodiment is disposed on the exit surface 丨Ua of the light collecting element 丨12. Therefore, when the sun The light 102 enters the multi-band concentrator n-plane (10) and is incident on 槪(4), and illuminates the exit surface 112a, and enters the grating 114, and the sunlight after the stray light is split by 1〇2. Three different wavelengths of light beams are collected on different light sources (λ, , =2, and 3) on different light collecting surfaces A to different collecting spots, and energy conversion elements m, 132 are disposed at corresponding positions. Received by 133. As can be seen from the above embodiments, in the multi-band concentrator no, the grating 114 can be set in the set. The incident face leg or the exit face 112a of the component 112 is not limited thereto. The difference between the embodiment of FIG. 7 and the FIG. 6 is that the light collecting component used in the b ^ example is different. 112 is a plano-convex lens. Since the grating U4 is disposed on the exit surface 112a of the light collecting element 112 (ie, the plane of the plano-convex lens), in the present embodiment, the grating used may be an equal-period grating, that is, the grating m projection The TL (four) phase (piteh) of the curved surface of the convex lens towel is equal. In the embodiment of FIG. 6, the grating 114 is disposed on the exit and the 集 (ie, the convex surface of the lenticular lens) of the light collecting element (1). The grating μ used may also be an equal-period grating, that is, the lions (pitch) of the tangent of the grating 114 projected onto the lenticular lens are equal. It is to be noted that only the design of the period in which the grating 114 is projected to the cut 'line TL can be two cycles. 'It is known to those skilled in the art that the period of the grating m can have different design changes'. limit.帛8图"' is not a reflective multi-band concentrating and energy-removing set 100. Unlike the previous embodiment, the sunlight 1 〇 2 is from the phase 201230369 corresponding to the energy conversion element group 130. The light receiving surface i30a enters the light in the back direction (into the multi-band concentrator 110), and instead of the sunlight 1〇2 as in the foregoing embodiment, the light is incident from the light-receiving surface i30a of the energy conversion element group 130. Therefore, in the present embodiment, the light collecting element 112 can be a reflective collecting lens, wherein a reflecting surface can be formed on the exit surface 112a or the incident surface U2b of the light collecting element 112, and the grating 114 is formed on the light collecting element. 112 out of the face 112 & When the sunlight 1〇2 enters the multi-band concentrator 11, the light is split by the grating 114, and then enters the light collecting element 112 to collect light. Since the emitting surface 112a or the incident surface i12b is a reflecting surface, the light splitting is performed. The subsequent light beam is reflected in the light collecting element 112, and is collected on the light collecting surface a, and then enters the energy conversion element group 13A located on the light collecting surface A. In another embodiment, the multi-band concentrator 110 can be integrally formed, i.e., the light collecting element 112 is integral with the grating. In this case, a reflective layer, such as a coating metal, can be disposed on the surface of the grating m. When the sunlight is moved into the multi-band concentrator 110, it is directly reflected, concentrated, and split in the grating 114, and the light source is also collected on the concentrating surface. For the actual design of the multi-band light collecting and energy conversion mode, the group 100 can be referred to, for example, "Fig. 9". Here, a lenticular lens is used as the light collecting element ιΐ2, and the light shed ΐ4 can be designed to follow the incident light. The three-band light with wavelength division is λ], ^, and the surface of the basin is also produced, and 2=__ and A3=7〇〇nm, which are correspondingly disposed on the light collecting surface of the light collecting surface. For the ΐ32 and 133, the energy conversion elements 131, 132, and 133 in the "Fig. 2" can be selected to have a good absorption coefficient for the light having a wavelength of _ 6 00 Å and · nm. When the sun is fine, the 'multi-light and energy conversion charm (10), the width D and the thickness of the first element m are 8em and Iem respectively, and the refractive index of the material used for the light collecting element 112 201230369 is 149, the light collecting element U2 The scale radius (8) is 12.8 cm, grating! 14 The period d projected to the tangent is d, the diffraction order of the grating i μ (m) is the total width d of the energy conversion element group 13 (), 15 (10), and the human emitting surface of the collecting S piece U2 (10) The lengths of the lines m, H2, and H3 from the center point to the center point of the light-receiving element (3), 132, and 133 light-receiving surface 130a are 27.6 〇cm, 27.63 cm, and 27.66 em, respectively, and the lines m, H2, H3 and the light are received. The angle of the normal line of the surface 130a is 5.74. , 6.89. And 8.05. . Further, referring to Fig. 10, the grating 114 may be composed of two or more sub-gratings 115 and outputs. The secondary gratings 115, 116 can be staggered. Moreover, the secondary gratings 115, 116 may have the same period or different periods, and may have different designs according to actual needs. Here, each of the sub-gratings 115' 116 can form the incident light sources on the collecting surface A to form respective sub-glues, so that the sub-concentrating_superimposing can obtain a central flat total collecting spot, thereby avoiding excessive concentration of energy. In other words, each of the condensing spots corresponding to each of the energy conversion elements 13 and 132 can be composed of two or more sub-concentrations. In this way, the amount of energy can be avoided and the temperature of the 7L piece set 130 is increased. Please refer to the "U-picture" for the above-mentioned image of the spotlighting total spotlight. The level of the towel (10) is the horizontal position of the set a, and the straight axis is the intensity. As can be seen from the figure, multiple Adjacent secondary spotlights are formed into a total spot (only the secondary spot in the picture) and the secondary spot 2, but not the limit of this proposal). "One Referring to Figure 12, more than two multi-band concentrating and energy conversion modules (10) and .3 can be installed in a solar power system 10+. These multi-band concentrating and energy conversion modules are full, 〇〇1〇〇2, 1〇〇_3 can be side by side 201230369 configuration. That is, the multi-band concentrator and the energy conversion module 〇〇_!, 1〇〇_2, and 1〇〇_3 of the multi-band concentrators 110-1, 110_2, and 110_3 are arranged adjacent to each other in order. The energy conversion component groups 130-1, 130-2, and 130-3 of the different multi-band light collecting and energy conversion modules 1〇(M, 1〇〇_2, 1〇〇_3 are not adjacent to each other, that is, each other. According to the multi-band concentrating and energy conversion module of the present proposal, the multi-band concentrating light is used to divide the sunlight into beams of different wavelength bands and collect them in respective corresponding directions. The energy conversion element is such that the energy conversion element has good conversion efficiency, thereby improving the total energy conversion efficiency. Moreover, the use of the multi-band concentrator can also reduce the utilization rate of the energy conversion element material. Finally, please refer to "13th" FIG. 4 is a multi-band concentrating and energy-switching structure according to a seventh embodiment of the present invention. The chopper-wave and energy conversion module 1 〇〇 includes a multi-band concentrator 110 and an energy conversion element group. 13〇, and arranged in the multi-band collecting light H 1H) and the energy conversion element group 丨 3G H sub-mirror i4 〇. The multi-band concentrator 11G includes a grating 114 and a collecting member 112. The light collecting element U2 of the multi-band concentrator 110 collects the incident light source on a collecting surface A. The optical system splits the riding light band incident on the multi-band collecting wire 11Q into a light beam. The secondary mirror (10) is used to guide, split, and collect the light beam into the plurality of focused spots. Therefore, when the collected light beam passes through the secondary mirror 140, the deviation I of the incident angle of the light beam incident on the energy conversion element group can be reduced without causing the concentrated spot to deviate from the energy conversion element group B0. Therefore, the energy conversion element group can convert the incident light into energy according to its absorption band. Although this proposal is disclosed above in the foregoing embodiments, it is intended to limit the proposal. In the spirit and scope of this (4), the changes and refinements are all within the scope of patent protection of this proposal.
