Abstract

We report that n-type single crystals of n-CuInSe₂ in aqueous polysulfide solution exhibit high quantum efficiencies of 0.8-0.9 in the wavelength region between 600-1150 nm when used as photoanodes in photoelectrochemical cells. Photocurrents of 28 mA/cm² were measured on a "winter" day in Rehovot (71 mW/cm²) which corresponds to 40 mA/cm² under AM1 (Air Mass 1) conditions (100-mW/cm² sunlight). Stability tests of n-CuInSe₂ photoanodes (20 000-C/cm ² photocharge passage) at short circuit current densities of 40 mA/cm² have shown no deterioration whatsoever of the measured photocurrents.
