METHOD FOR PRODUCING OPTIMIZED SOLAR CELLS

摘要

The invention relates to a method for producing a solar cell wafer with a p-n transition and an emitter layer. In said method, the emitter layer is irradiated with a monochromatic UV radiation (23) of 172 nm (+-10 nm) in an oxygen-containing atmosphere after the concluding etching and cleaning step and prior to the application of additional layers. A suitable light source (2) is specified for generating the monochromatic UV radiation. The treatment according to the invention of the substrate (1) results in an improved growth of subsequent layers on the irradiated surface of the solar cell.
