NEW INTRINSIC ABSORBER LAYER FOR PHOTOVOLTAIC CELLS

摘要

So as to manufacture an intrinsic absorber layer of amorphous hydrogenated silicon within a p-i-n configuration a solar cell by PeCvD deposition upon a base structure, thereby improving throughput an simultaneously maintaining quality of the absorber layer, a specific processing regime is proposed, wherein in the reactor for depositing the addressed absorber layer a pressure of between 1 mbar and 1.8 mbar is established and a flow of silane and of hydrogen with a dilution of silane to hydrogen of 1:4 up to 1:10 and generating an RF plasma with a generator power of between 600W and 1200W per 1.4m2 base structure surface to be coated.
