Definitions
- the present invention relates to a rear contact heterojunction photovoltaic cell and its manufacturing method.
- a photovoltaic module comprises a plurality of photovoltaic cells (or solar cells) connected in series and / or in parallel.
- a photovoltaic cell is a semiconductor diode designed to absorb light energy and convert it into electrical energy.
- This semiconductor diode comprises a so-called PN junction between two silicon layers respectively doped with P and N. During the formation of the junction, a potential difference (and therefore a local electric field) appears, due to the excess of free electrons in the N layer and the free electron defect in the P layer.
- Solar cells based on monocrystalline silicon or multicrystalline are traditionally developed by taking the positive and negative contacts on each of the faces of the cell.
- the rear face is generally completely covered with metal since only the conductivity (no light having to cross the rear face), while the front face, that is to say that which is illuminated, is contacted by a metal grid which allows most of the incident light to pass through.
- the advantage of this technique is to have no shading on the front face while reducing the ohmic losses due to metal contacts since they cover a much larger surface of the cell.
- junction In order to make selective contacts on one side, there are two possible types of junction: the so-called homojunction contact (crystalline / crystalline contact), which can for example be obtained by diffusion of dopants under the effect of a high temperature ( oven); and the so-called heterojunction contact (crystalline / amorphous contact), which can for example be obtained by deposition of hydrogenated amorphous silicon (a-Si: H) doped.
- homojunction contact crystalline crystalline contact
- heterojunction contact crystalline / amorphous contact
- Document US 2008/0035198 provides an example of a homojunction type rear contact photovoltaic cell.
- Document US 2007/0137692 provides another example, in which two superposed metal layers are provided for the collection of the respective charge carriers, separated from one another and separated from the substrate by an insulator, the contact of each layer. metal with the substrate being provided by laser annealing of the metal layer at point locations.
- the heterojunction-type contacts have the advantage of offering a higher open circuit voltage (and a lower high-temperature output loss) than the homojunction-type contacts.
- the heterojunction-type contacts make it possible to achieve both passivation and contact.
- WO 03/083955, WO 2006/077343, WO 2007/085072, US 2007/0256728, EP 1873840 all disclose heterojunction semiconductor devices comprising a crystalline silicon substrate covered on one and the same rear face by respective areas of N-doped amorphous silicon and P-doped amorphous silicon, which are separated by insulating portions, and which are covered with respective metallization areas for the collection of charge carriers.
- a disadvantage of all these devices is that their manufacture requires two separate stages of amorphous silicon deposition, for example by using a mask at each step or by first depositing one of the amorphous silicas, then etching it before depositing the other amorphous silicon.

- a crystalline semiconductor substrate having a front face and a rear face

- the invention also relates to a method of manufacturing a semiconductor device comprising:
- a crystalline semiconductor substrate having a front face and a back face
- ⁇ forming an inner part of the second metallization region, which crosses the back passivation layer and forms in the substrate a region having a higher electron acceptor concentration to the rest of the substrate, laser annealing the part of surface of the second metallization zone.

- This semiconductor device can in fact be obtained with a single step of deposition of doped amorphous silicon on the rear face and a single step of depositing metal material for collecting charge carriers on the rear face.

- the invention provides photovoltaic cells with rear contact, that is to say having no shading on the front face, and having ohmic losses due to minimal metal contacts; in addition, the invention makes it possible to dispense with any transparent conductive oxide on the front face, which allows a short-circuit current, and therefore a high efficiency.
- the semiconductor devices of the invention have a heterojunction type contact N (that is to say a contact with an amorphous silicon region), which guarantees a very good passivation; and a contact P of homojunction type, which combined with the first makes it possible to use a greatly simplified manufacturing process without unduly degrading the overall passivation.
- Figure 1 shows schematically an embodiment of a semiconductor device (including a photovoltaic cell) according to the invention, during manufacture, in section (and in partial view). The different layers of material are not scaled in the figure.

- Figure 3 shows a view of the rear face of this semiconductor device at the end of its manufacture.
- Figure 4 shows a partial view of this device, in longitudinal section corresponding to the line A-A in Figure 3.
- a semiconductor device according to the invention can be manufactured as follows.
- a crystalline semiconductor substrate 1 having a front face 1a and a rear face 1b.
- the crystalline semiconductor substrate 1 is a substrate (or "wafer") of crystalline silicon, in particular monocrystalline or polycrystalline (preferably monocrystalline), in the form of a plate.
- This substrate can be N- or P-doped.
- the use of an N-type doped substrate is particularly advantageous insofar as the lifetime of this substrate is higher.
- an N-type doped substrate is used as an example.
- the substrate 1 is advantageously devoid of any oxide material.
- the substrate 1 has sufficient doping to have a resistivity of between about 0.1 and 1 ⁇ .cm.
- the front passivation layer 3 advantageously comprises an amorphous intrinsic hydrogenated silicon layer 6 in contact with the substrate 1 and a doped hydrogenated amorphous silicon layer 7 disposed thereon.
- the doped hydrogenated amorphous silicon layer 7 is N-doped when the substrate 1 is N-type; or it is P-doped when the substrate 1 is of type P.
- the rear passivation layer 2 advantageously comprises an amorphous intrinsic hydrogenated silicon layer 4 in contact with the substrate 1 and a doped hydrogenated amorphous silicon layer 5 disposed thereon.
- the doped hydrogenated amorphous silicon layer 5 is N-doped, whatever the type of doping of the substrate 1.
- the passivation layers before 3 and back 2 play a role of passivation in two complementary ways: on the one hand the presence of amorphous silicon on each side 1 a, 1 b of the crystalline substrate makes it possible to render the surface defects of the substrate inactive, by avoiding the bonds hanging on the surface, which avoids the recombination of the charge carriers before their collection; on the other hand, the presence of the doped hydrogenated amorphous silicon layers 5, 7 makes it possible to create a front surface field, respectively a rear surface field, which also improves the collection of the charge carriers.
- the deposition of the two intrinsically hydrogenated amorphous silicon layers 4, 6 and the two doped hydrogenated amorphous silicon layers 5, 7 can be carried out for example by the technique of plasma enhanced chemical vapor deposition (PECVD) or by the technique of low pressure chemical vapor deposition (LPCVD). Each of the layers can cover the entire surface of the substrate 1.
- PECVD plasma enhanced chemical vapor deposition
- LPCVD low pressure chemical vapor deposition
- an anti-reflective layer 8 is advantageously provided on the front passivation layer 3.
- the latter comprises a dielectric material, preferably hydrogenated amorphous silicon nitride. Preferably, it extends over the entire surface of the front passivation layer 3. It can be deposited for example according to the PECVD or LPCVD technique.
- the main role of the anti-reflective layer is to eliminate as much as possible the reflection of light arriving on the device from the front side.
- the refractive index of the anti-reflective layer may for example be close to 2.
- a textured silicon can be used to improve the collection of light.
- a metal layer 9 is deposited on the rear passivation layer 2.
- it can be carried out by evaporation. spraying or electrochemical deposition.
- the metal layer 9 is preferably based on aluminum.
- the metal layer 9 initially covers the entire surface of the rear passivation layer 2; then, a portion of the metal layer 9 (by etching or otherwise) is selectively removed in order to obtain a first metallization zone 10 and a second metallization zone 11 separated from the first metallization zone 10.
- the first metallization zone 10 and the second metallization zone 11 form an interdigitated structure as shown in FIG. 3, that is to say a structure in which the two metallization zones 10, 11 form Inverted and nested combs.
- the metallization zones 10, 1 1 are intended for the collection of the respective charge carriers.
- An interdigitated structure allows an electrical connection of the particularly simple device.
- the metallization zones 10, 1 1 selectively to the surface of the rear passivation layer 2, so as to obtain directly the desired pattern (for example, interdigitance).
- the desired pattern for example, interdigitance
- the metallization zones 10, 1 1 are made from the same material (preferably based on aluminum): this embodiment is indeed the simplest to put implemented. However, it is also possible to prepare metallization zones 10, 1 1 of composition different from each other. In this case, at least the second metallization zone 11 is preferably based on aluminum.
- a laser annealing step (or "laser firing") of the second metallization zone 11 is then carried out.
- Laser annealing consists in applying laser pulses to the second metallization zone 11 so as to induce, for a very short time, a melting / solidification cycle on the second metallization zone 11 as well as on a certain thickness of the sub-silicon. underlying.
- the metal especially aluminum
- the metal diffuses rapidly in the liquid silicon.
- the silicon is again epitaxied from the underlying solid silicon; the atoms (dopants) of the metal (in particular aluminum) having diffused during the melting cycle are then put in substitutional sites in the reconstructed crystal.
- the second metallization zone comprises, on the one hand, a surface portion 11, disposed on the rear passivation layer 3 and essentially corresponding to the second metallization zone before laser annealing; and on the other hand an inner portion 12 passing through the rear passivation layer 2 and penetrating into the substrate 1, this inner portion 12 being obtained by diffusion of atoms (especially aluminum) during laser annealing.
- the inner portion 12 of the second metallization zone therefore comprises a region of the substrate 1, situated below the surface portion 11 of the second metallization zone, which is doped with P + type (that is to say which has a high concentration of P-type dopants, especially aluminum atoms).
- the inner portion 12 of the second metallization zone thus forms in the substrate 1 a region in which the concentration of electron acceptors is greater than the rest of the substrate 1, and that the substrate 1 is N-type or of type P.
- a PN-type junction is thus formed between the region of the substrate 1 modified by laser annealing and the rest of the substrate 1; and when the substrate 1 is of the P type, a PP + type junction is thus formed.
- the extreme rapidity of the solidification front during laser annealing favors the formation of square profiles, and allows to achieve higher activation rates than those obtained with conventional techniques.
- the laser energy determines the thickness of the region of the substrate 1 thus doped.
- the dopants are electrically active, the doping profile is quasi-square, with very steep sides.
- Nd-YAG pulsed laser or a pulsed UV excimer laser.
- a Nd-YAG tripped laser can be used at 1064 nm in TEM 0 o mode, with a power of 300 to 900 mW and a pulse duration of 100 ms with a repetition frequency of 1 kHz.
- the laser power and the pulse duration are adjusted according to the desired annealing depth and induced doping.
- the laser scroll speed and frequency are adjusted to adjust the distance between the laser impacts.
- the distance between the laser impacts along the bands of the pattern must be low enough to limit ohmic losses and optimize load collection.
- the first metallization zone 10 remains present only above the rear passivation layer 2 and more precisely above the N-doped hydrogenated amorphous silicon layer. Therefore, this first metallization zone 10 ensures a contact of N type, that is to say is adapted to the collection of electrons.
- the second metallization zone has been converted into P-type contact, that is to say, it is adapted to the collection of holes.
- the geometry of the semiconductor device thus obtained may be as follows:
- Substrate 1 thickness between 150 and 300 ⁇ .
- Intrinsic hydrogenated amorphous silicon layers 4, 6 thickness between 1 and 10 nm, especially between 3 and 5 nm.
- Dielectric amorphous silicon doped layers 5, 7 thickness between 5 and 30 nm, especially between 5 and 15 nm.
- - Anti-reflective layer 8 thickness between 50 and 100 nm.
- First metallization zone 10 and surface portion 1 1 of the second metallization zone thickness of between 2 and
- these metallization zones comprise alternating parallel strips.
- Each band may have a typical width of 50 to 400 ⁇ and in particular 50 to 200 ⁇ (for example about 100 ⁇ ) and two strips may be separated by a typical distance of 50 to 200 ⁇ (for example about 100 ⁇ ).
- the diffusion length of the charge carriers in the rear passivation layer 2 is typically about 20 nm due to the presence of doped amorphous silicon. As a result, the charge carriers can pass through the rear passivation layer 2 according to its thickness, but can not essentially cross it in a direction parallel to the rear face 1a of the substrate 1. Consequently, there is practically no possible short circuit between the two respective metallization zones.
- the above description relates to semiconductor devices that are generally used as photovoltaic cells.
- One or more of these devices may be incorporated as a photovoltaic cell module.
- a number of photovoltaic cells may be electrically connected, in series and / or in parallel, to form the module.
- the module can be manufactured in different ways. For example, it is possible to arrange the photovoltaic cells between glass plates, or between a glass plate and a transparent resin plate, for example ethylene vinyl acetate. If all the photovoltaic cells have their front face oriented in the same direction, it is also possible to use a non-transparent plate (metal, ceramic or other) on the rear side. It is also possible to manufacture modules receiving light on two opposite faces (see for example US 6,667,434 in this regard). A sealing resin may be provided to seal the sides of the module and protect it from atmospheric moisture. Various resin layers may also be provided to prevent the undesirable diffusion of sodium from the glass plates.
- the module furthermore generally comprises static conversion means at the terminals of the photovoltaic cells.
- it may be DC-AC conversion means (DC / AC) and / or DC-DC converting means (DC / DC).
- the static conversion means are adapted to transmit the electrical power supplied by the photovoltaic cells to a load of an external application - battery, electrical network or other. These static conversion means are adapted to reduce the transmitted current and to increase the transmitted voltage.
- the static conversion means may be associated with management electronics.
