Amorphous silicon photovoltaic device having two-layer transparent electrode
An amorphous silicon semiconductor of the general formula: a-Si(/sub 1//sub -/ /SUB x/ /sub -/ /SUB y/)C /SUB x/ N /SUB y/ containing hydrogen and/or fluorine, which provides an amorphous silicon PIN junction photovoltaic device having an improved conversion efficiency when it is used as a P-type or N-type layer on the light impinging side of the PIN junction photovoltaic device. Also, the conversion efficiency of an amorphous silicon PIN junction photovoltaic device is improved by using a two-layer film structure of ITO and SnO/sub 2/ as a transparent electrode for the photovoltaic device, with the SnO/sub 2/ layer contacting the P or N layer. The improvement is particularly marked in the case of heterojunction photovoltaic devices.
