Abstract
An amorphous photovoltaic energy conversion element for use in a solar cell is composed of a first layer formed of a p-type material, a second layer formed of an intrinsic amorphous semiconductor having a potential gradient formed therein and a third layer formed of a metal capable of coming into ohmic contact with the aforementioned intrinsic layer of amorphous semiconductor and exhibiting a lower work function than the work function of the intrinsic layer of amorphous semiconductor.
