Abstract

Polycrystalline layers of As-doped pyrite (FeS//2) have been produced in bromine atmosphere with the aim of developing this sulfide material for solar energy applications. Its photoelectrochemical behavior in contact with an aqueous I//3** minus /I//2 electrolyte was investigated. It operated as a photoelectrochemical solar cell and showed reasonably stable behavior under illumination. Optical measurements performed on FeS//2 show that visible light is absorbed in an extremely thin layer of 160 A in spite of the apparently indirect gap of this semiconductor (E//g equals 0. 95 ev). This would make this photosensitive material an interesting candidate for thin-layer solar cells.
