Abstract
An amorphous film solar cell of p-i-n heterojunction type, which is produced through the combination of group III-V compound amorphous semiconductor films with a layer of fluorinated or hydrogenated amorphous silicon semiconductor material. Selection of the p-i-n layer construction is easier compared to film solar cells of conventional fluorinated or hydrogenated amorphous silicon semiconductor material, efficiency is improved, and there is an increased degree of freedom in choice of the apparatus.
Claims2
An amorphous film solar cell of heterojunction type having a p-i-n construction, comprising a p type or n type amorphous semiconductor layer made of a group III-V material and at least an i (intrinsic) type semiconductor layer made of fluorinated or hydrogenated amorphous silicon semiconductor material.
