Abstract

A semiconductor device for converting light into electric energy comprises at least one layer of amorphous silicon with a surface thereof which is intended to be exposed to light covered by a cover layer of polycrystalline silicon. The use of the polycrystalline silicon increases the current yield in the blue light range of the solar spectrum. A method of producing such a semiconductor device is also disclosed.
