ABSTRACT:
Solar cells with photoanodes based on CuInS.sub.2 semiconductor material produced by specially adapted methods, permit the transformation of light into electric energy with a good efficiency. The semiconductor material according to the invention comprises inclusions of extraneous phases, namely In.sub.2 S.sub.3, In and/or Cu.sub.2-x S (0.ltoreq.x.ltoreq.1) in a concentration between 5 per thousand and 5 percent, in the CuInS.sub.2. The energy gap of this material is 1.5 eV. Working electrodes for photoelectrochemical solar cells or solid state solar cells can be constructed.
