ABSTRACT:
A solar cell comprising a substrate having a surface, a first conductive layer disposed on the surface of said substrate, said first conductive layer having a roughened surface provided with irregularities at the surface thereof, a second conductive layer disposed on the roughened surface of said first conductive layer, said second conductive layer having a roughened surface provided with irregularities, a semiconductor active layer disposed on the roughened surface of said second conductive layer and an upper conductive layer disposed on said semiconductor active layer, wherein said second conductive layer is formed of a 10 nm to 150 nm thick highly reflective metal film. The solar cell exhibits an improved photoelectric conversion efficiency and can be mass-produced at an improved yield.
