Abstract

A semiconductor solar cell for the conversion of light to electric energy comprises at least one layer of amorphous silicon, a cover layer of poly-crystalline silicon and an anti-reflection layer of semiconducting transparent oxide of a refractive index of less than 2.8. The cover layer of poly-crystalline silicon has an optical density ##EQU1## or it may be ##EQU2## The cover layer is arranged between the anti-friction layer and the layer of amorphous silicon.
