Definitions
- the present invention relates to a method for producing a solar cell from a silicon substrate according to claim 1.
- Solar cells usually consist of a silicon substrate.
- solar cells are provided with a passivation layer.
- passivation layer To passivate silicon surfaces of solar cells, dielectric thin films have hitherto been used.
- silicon nitride films deposited primarily with a plasma process have become established.
- thermally grown silicon oxide layers offer significantly better passivation properties.
- the process requires a high thermal budget, which can adversely affect the diffusion profiles.
- Another disadvantage is that the process is inherently two-sided. However, since the passivation layer is typically required only on one side of the solar cell, the other side of the solar cell must be masked.
- the one-sidedness of the oxidation is achieved by front side masking with deposited SiN.
- a thin layer ( ⁇ 20 nm) of oxide is grown and then thickened by deposited oxide or nitride. Since the boundary layer between Si0 2 and Si is primarily relevant for the passivation, a passivation quality comparable to the purely thermal oxide is achieved by the layer stack.
- the disadvantage of this, however, is that the method is technically complex and expensive.
- the present invention relates to a method for producing a solar cell from a silicon substrate, which has a first main surface serving as a light incident side in use and a second main surface serving as a back side, with a passivation layer on the second main surface, comprising the following steps: Applying an oxide-containing layer to the second main surface of the silicon substrate; and heating the silicon substrate to a temperature of at least 800 ° C to densify the oxide-containing layer and to oxidize the interface between the oxide-containing layer and the second major surface of the substrate
- Silicon substrate for the formation of thermal oxide wherein an oxygen source releases oxygen for the oxidation.
- a process atmosphere of the silicon substrate in particular 0 2 and / or H 2 0 comprising, can act as an oxygen source.
- the oxide-containing layer can be applied such that it, in particular Si0 2 , Zr0 2 , SiO a N b and / or SiO a C b , wherein each b ⁇ a, comprising, is oxygen-permeable.
- the oxide-containing layer in particular comprising SiO 2
- SiH 4 can be applied to the second main surface of the silicon substrate by a CVD or a PECVD method, in particular using SiH 4 . This further reduces the cost of the process since the CVD and PECVD processes are very cost effective.
- the oxide-containing layer is applied uniformly to the second main surface.
- the oxide-containing layer may be a superstoichiometric oxide, in particular SiO 2 + x : H and / or a low-density oxide and / or a hygroscopic oxide Oxide, preferably BSG, PSG and / or TEOS oxide, and the oxide-containing layer may function as the oxygen source.
- a silicon oxide layer formed during heating of the silicon substrate therefrom may be etched away from the first main surface and a portion of the oxide-containing layer may be etched away from the second main surface.
- a dopant in particular boron, preferably by means of boron tribromide, and / or phosphorus, preferably by means of phosphorus oxychloride, can be further diffused into the two main surfaces after the application of the oxide-containing layer, wherein the dopant is diffused during the step of heating the silicon substrate the first major surface diffuses, and wherein the oxide-containing layer acts as a masking layer of the second major surface during heating.
- a doped layer can easily be formed on the first main surface of the silicon substrate, which can function as an emitter, while the dopant does not diffuse into the second main surface of the silicon substrate.
- Dopant-silicon compound layers formed during heating of the silicon substrate may be etched away from the first main surface and / or the second main surface.
- An advantage of this is that the silicon of the silicon substrate is exposed on the first major surface and the oxide-containing layer is exposed on the second major surface.
- a surface structure may be applied to the first main surface and / or the second main surface before the application of the oxide-containing layer.
- the second main surface can be planarized before the application of the oxide-containing layer.
- the application of the oxide-containing layer on the second main surface is significantly improved.
- the first main surface and / or the second main surface can be cleaned before the application of the oxide-containing layer, in particular with HNO 3 .
- An advantage of this is that the application of the oxide-containing layer is further improved.
- boron or phosphorus may also be diffused into the second major surface or implanted by ion implantation, which is activated upon heating of the silicon substrate, to create a back surface field (BSF) layer.
- BSF back surface field
- the back-surface field improves the efficiency of the solar cell because the back-surface field is a barrier to the electrons, which therefore does not gain access to the surface of the silicon substrate.
- a SiN anti-reflection layer may further be applied to the first main surface and / or the oxide-containing layer of the second main surface.
- the anti-reflection layer reflects less light from the silicon substrate, thereby providing more light into the substrate
- Silicon substrate penetrates. This increases the efficiency of the solar cell.
- one or more holes can be produced by means of a laser through the silicon substrate for connecting the first main surface to the second main surface, in particular by means of a laser, before the application of the oxide-containing layer.
- the advantage of this is that an electrical connection is formed from the first main surface to the second main surface or vice versa through the holes in a simple manner.
- a dopant in particular boron, preferably by means of boron tribromide, and / or phosphorus, preferably by means of phosphorus oxychloride, is diffused into both main surfaces; the dopant is diffused by heating the silicon substrate into the silicon substrate to form an emitter layer on the first major surface and an emitter layer on the second major surface; dopant-silicon compound layers formed by heating the silicon substrate are etched away from the first main surface and / or the second main surface; a masking layer, preferably SiN, is applied to the first major surface; and the emitter layer of the second main surface is removed, in particular by etching, wherein the SiN layer functions as a masking layer of the first main surface during the removal.
- a dopant in particular boron, preferably by means of boron tribromide, and / or phosphorus, preferably by means of phosphorus oxychloride, is diffused into both main surfaces; the dopant is diffused by heating the silicon substrate into
