An amorphous solar cell including an amorphous SiGe film which is produced by a glow discharge method using a mixed gas obtained by mixing Si.sub.2 H.sub.6 and GeH.sub.4 or obtained by diluting Si.sub.2 H.sub.6 and GeH.sub.4 with a predetermined dilution gas such that the ratio of GeH.sub.4 to (Si.sub.2 H.sub.6 +GeH.sub.4) is 0.1 to 0.4.

Amorphous solar cell

A sun light electricity generator comprising an amorphous sun light battery, which comprises: a conductive substrate which also constitutes an output electrode; amorphous semiconductor layers provided on the substrate, said layers constituting a p-i-n junction structure for a sun battery element and for a protection diode; an electrode for the sun battery element and an electrode for the protection diode, both provided on the light incident amorphous layer but separated from each other; and an electrode for connection to another generator provided on a region of the substrate where the amorphous layers are not provided.
