Solar cell i.e. silicon solar cell, for converting solar radiation into electrical energy, has amorphous layer modulated by adjusting factors and/or refraction index of doped layer, where layer thickness is in preset values
The cell (1) has heterojunction p-n transition (2) formed between a crystalline silicon substrate (3) and an amorphous doped layer (5). The amorphous doped layer comprises silicon monoxide, silicon nitride and/or silicon carbide layers modulated by adjusting factors and/or refraction index of the amorphous doped layer during deposition of the amorphous doped layer. The refraction index of the amorphous doped layer is about 2 and 3, conductivity of the amorphous doped layer is in preset values, and thickness of the doped layer is about 50 nm to 300 nm. The solar cell comprises a layer sequence made from ethyl vinyl acetate and glasses. An independent claim is also included for a method for manufacturing a solar cell.
