Definitions
- the invention relates to a crucible for a device for producing a block of crystalline material by directed crystallization, having side walls and a bottom, the bottom having, parallel to a. axis substantially perpendicular to the bottom, thermal transfer properties much higher than those of the side walls along said axis.
- the conventional technologies for obtaining solid multicrystalline silicon for photovoltaic application find their economically by limiting the time of crystallization necessary, related to the volume and height of the silicon block, - technically by the performance of semiconductor devices, related to the diffusion length of the minority carriers, by uncontrolled lateral growths generating material losses and requiring peeling, by the diffusion of impurities from the crucible into the silicon, requiring peeling.
- the solidification of silicon from a liquid silicon bath is obtained typically by directed crystallization, that is to say by migration of a solidification front (solid / liquid interface) from an initially solidified part. , in particular a seed or a first layer crystallized by local cooling.
- a solidification front solid / liquid interface
- the solid silicon block grows progressively by feeding on the liquid bath.
- the two methods conventionally used are the Czochralski process, the Bridgman process or their variants. According to the method of
- Czochralski a seed, often oriented relative to a crystalline axis of solid silicon, is dipped in the molten bath to be slowly raised.
- the liquid silicon bath and the thermal gradient then remain stationary, whereas according to the Bridgman type method, the bath is displaced with respect to the thermal gradient, or the thermal gradient with respect to the bath.
- the present invention relates to the Bridgman method.
- a container containing silicon is conventionally constituted by a crucible 1 molded in quartz, disposed in an insulating casing 2 of insulating material.
- a thermal gradient is created between heating means 3, arranged at the upper part of the insulating casing 2, and cooling means 4, arranged at the bottom of the insulating casing 2.
- the solid silicon 5, obtained from the liquid silicon 6, often has inhomogeneities, for example a structure in fine particles (“microgrit”) having not reached the critical size of the crystallization nucleus and being in the form of clusters, which reduces the diffusion length of the minority carriers .
- JP 07010672 discloses a platinum crucible installed in an electric furnace for the growth of single crystals according to the Bridgman method.
- the crucible contains a liquid brought into contact with a crystal serving as a crystallization seed and disposed in the lower part of the crucible.
- a transparent substance is installed under the crystal.
- the crucible material is reflective. Such a crucible is difficult to implement.
- FR 2509638 discloses a mold for molding silicon ingots for use as a material for producing solar cells.
- the mold comprises, in a metal outer envelope, a thick, thermally insulating coating, for example made of ceramic fibers, disposed around the thin side walls of a container made of graphite fibers or ceramic.
- a bottom layer, for example of siliceous sand, is placed under the container.
- the object of the invention is to remedy these drawbacks and, in particular, to provide a device and a method for manufacturing a block of crystalline material by directed crystallization, making it possible to obtain, in particular, sufficiently pure multi-crystalline silicon and with a crystalline structure suitable for photovoltaic applications, while reducing manufacturing costs.
- this object is achieved by the appended claims and, more particularly, by the fact that the bottom and the side walls are constituted by materials having the same main chemical constituents.
- FIG. 1 shows a device for manufacturing a crystalline material block by directed crystallization according to the prior art.
- FIG. 2 shows a device according to the invention comprising a crucible according to the invention.
- the device for manufacturing a block of crystalline material by directed crystallization comprises an assembly or an insulating casing 2 and a crucible whose bottom 7 is integral with the lateral walls 8.
- the bottom 7 and the lateral walls then form a single piece.
- the bottom 7 has heat transfer properties, parallel to an axis substantially perpendicular to the bottom 7, much greater than those of the side walls 8 of the crucible, along said axis.
- the heat transfer properties include, on the one hand, the thermal conductivity of the material and, on the other hand, its transmission coefficient of infrared radiation.
- the bottom 7 and the side walls 8 are constituted by materials having the same main chemical constituents.
- the bottom 7 can be linked, without difficulty, for example welded, to the side walls 8 and the thermal expansion coefficients of the materials are substantially the same.
- the main constituent of each of the materials may, for example, be the chemical entity Si0 2 , the spatial arrangement of the chemical entities
- SiO 2 constituting the bottom 7 being different from the arrangement in space of the chemical entities Si0 2 constituting the side walls 8.
- Heating means 3 and cooling means 4 are respectively constituted by a heating resistor disposed above the crucible, in the insulating casing 2, and by a heat exchanger, placed under the crucible, in the insulating casing 2. Heating resistor and heat exchanger are wide enough to completely cover the crucible.
- the heating means may also be constituted by induction heating means.
- the bottom 7 of the crucible is transparent to infrared radiation, while the side walls 8 are opaque to infrared radiation.
- a crucible may consist of a bottom 7 of amorphous silica and side walls 8 made of opaque quartz ceramic.
- the materials have SiO 2 as the main constituent and are distinguished only by their crystallographic structure and the arrangement of the SiO 2 constituents in space.
- the infrared radiation, emitted by the solid silicon contained in the crucible is transmitted to the heat exchanger 4 through the amorphous, transparent silica, which makes it possible to evacuate the heat of the solid silicon 5 and to establish in the crucible a thermal gradient of at least 8 ° C / cm.
- a predetermined thermal gradient requires effective heat removal, proportional to the thermal gradient.
- the opacity of the side walls 8 prevents the exchange of infrared radiation through the walls, which would cause the convection of liquid silicon.
- the isothermal surfaces are substantially flat and parallel and, consequently, the solidification front is also substantially plane, parallel to the bottom 7 of the crucible.
- the side walls 8 of opaque quartz ceramic and the bottom 7 of amorphous silica are made integral, for example, by heating the portions, respectively of the side walls 8 and the bottom 7, intended to form the junction .
- the heating temperature is higher than the melting temperature of the materials, of the order of 2000 ° C and this can be achieved by means of a torch.
- the materials then bind intimately.
- thermal conductivities of the amorphous silica, on the one hand, and the opaque quartz ceramic, on the other, are practically of the same order, approximately 2 W / (m ° C). The difference in heat transfer is then solely due to the transparency of the infrared radiation.
- the thickness of the solid phase increases, so that the solidification front progresses upwards away from the crucible bottom.
- the silicon melting temperature being 1410 ° C.
- the isothermal surface of 1410 ° C. then moves away from the bottom of the crucible, which leads to a decrease in the temperature at the bottom of the crucible during the crystallization process.
- the power radiated by any body decreases with temperature. So that the thermal power discharged by the cooling means 4 remains substantially constant during the solidification time, it is possible to integrate in the device a graphite felt 9 (FIG. 2) disposed between the bottom of the crucible and the cooling means 4, and means 10 for compressing the graphite felt during the solidification of the silicon.
- the cooling means 4 and the graphite felt 9 are arranged between the compression means 10 and the crucible, so that the compression means 10 exert a pressure against the crucible and the cooling means.
- the thickness of the graphite felt 9 decreases and its thermal conductivity increases.
- the conductivity thermal transfer of the graphite felt 9 can then be controlled by the compression means 10.
- the compressive force can be gradually increased to compensate for the decrease in the heat transfer by radiation through the bottom of the crucible.
- the thermal gradient in the crucible can be controlled and maintained at a value between 8 ° C / cm and 30 ° C / cm, and preferably between 10 ° C / cm and 20 ° C / cm, which makes it possible to increase the crystallization speed.
- the thickness of the non-compressed graphite felt is 5mm, while its thickness is 3.5mm under compression.
- the heat exchanger typically comprises a heat transfer fluid circuit and, depending on the application, the fluid may be synthetic oil having, for example, a use temperature of less than 300 ° C. or a fluid operating at high temperature. for example a gas under pressure, for example helium. It is possible to vary the temperature of the heat transfer fluid in a controlled manner, to ensure that the discharged power remains constant during the solidification time.
- the bottom 7 and the side walls 8 are formed by plates made of the same material having anisotropic properties of thermal conduction. The thermal conductivity of the plates, in the plane of the plates, is much lower than their thermal conductivity perpendicularly to this plane.
- the crucible can be made with a graphite having strongly anisotropic properties, due to its geometric structure.
- the thermal energy of the silicon is transmitted to the heat exchanger by conduction through the bottom 7, while the thermal conduction in the side walls is very low parallel to an axis substantially perpendicular to the bottom.
- This embodiment also makes it possible to establish a thermal gradient of at least 8 ° C / cm and to produce a substantially plane solidification front.
- the crucible comprises a coating 11 on an inner face and / or an outer face of the side walls, which makes it possible to modify the thermal transfer properties of the side walls.
- a deposit of silicon nitride on the inner face of the side walls 8 for example, reduces the emissivity of the side walls 8 and thus reduce the thermal radiation transfer.
- a coating comprising a reflective material disposed on the outer face of the side walls 8, also reduces the heat transfer through the side walls 8.
- a 450mm side square crucible and 250mm height is filled with 50 liters of liquid silicon, which corresponds to 128 kg of silicon.
- the thickness of the side walls of the crucible is 10 mm and the bottom thickness of the crucible is 10 mm.
- the crystallization is advantageously carried out at a determined speed of 20 mm / h and lasts, therefore, 12 hours and 30 minutes.
- the initial temperature difference between the top and the bottom of the crucible is 375 ° C, which corresponds to a thermal gradient of 15 ° C / cm in the liquid phase.
- the power Pj dissipated by the Joule effect in the heating resistor is essentially recovered at the heat exchanger located under the crucible, neglecting the thermal losses transmitted by the insulating housing 2 to the outside.
- a power P L restored during crystallization by the latent heat of the liquid / solid transition, is recovered at the heat exchanger.
- the power P j depending on the thermal gradient in the liquid phase and the conductivity of the liquid silicon (56 W / (m ° C)), is of the order of 17 kW for the device considered in the example, while the power P L , depending on the crystallization speed, is of the order of 5 kW, the power discharged into the exchanger then being of the order of 22kW.
- a thermal power of 22 kW can be evacuated by radiation by a heat exchanger maintained at a temperature of 20 ° C., for a solid silicon temperature of 1150 ° C. at the bottom of the crucible.
- the emissivity of the silicon being approximately 0.5.
- the invention allows a controlled crystallization of multi-crystalline silicon, sufficiently pure and with a crystalline structure suitable for photovoltaic applications.
- the invention also makes it possible to obtain a faster crystallization rate to produce a multi-crystalline silicon block of greater height than the height obtained with the known techniques and thus to achieve a greater efficiency of the fluids used. for the cooling means. Thanks to the thermal gradient between 8 ° C / cm and 30 ° C / cm, the thermal anisotropy of the crucible and the thermal assembly around the crucible, the solidification front is better stabilized, the segregation of metallic impurities is improved and the size as well as the grain structure crystallins are improved. As a result, the multi-crystalline silicon thus obtained is characterized by a greater minority carrier diffusion length by virtue of which the performance of phosphoric acid devices is increased.
