||PCT/EP2014/056785||INSTITUT FÜR SOLARENERGIEFORSCHUNG GMBH||BRENDEL, Rolf.|
The invention relates to a method for producing a silicon substrate (1) for the production of a solar cell
, wherein the method comprises the following steps: providing an absorber layer (10) having a high-quality silicon layer (7), which has a high minority charge carrier lifetime of more than 2 μs, for example, and a layer thickness of less than 40 μs, for example, and attaching a carrier layer (12) onto the absorber layer, wherein the carrier layer has a low-quality polycrystalline silicon layer (11), which has a low minority charge carrier lifetime of less than 2 μs, for example, and a layer thickness of preferably more than 80 μs. The low-quality polycrystalline silicon layer (11) can be deposited from a gas phase, similarly to a Siemens process, wherein high deposition rates together with very low contaminants are possible. The produced silicon substrate (1) has sufficiently good electronic properties in the absorber layer thereof to be able to produce a solar cell
having high efficiency therefrom. The carrier layer having the low-quality polycrystalline silicon layer is used mainly for the mechanical stabilization of the silicon substrate, such that the silicon substrate can be processed further into a finished solar cell
similarly to a traditional silicon wafer. No ingot needs to be crystallized and then sawed into pieces in the production of the silicon substrate (1), whereby considerable costs can be saved.
