Paper Abstract

The photoelectrochemical responses of ternary, chalcogenide glasses of the form: V-VI-M have been surveyed where M=metal or chalcogen. Of those examined, the As-Se-Cu composition appeared most promising for solar energy conversion. In particular, glassy compositions at or near the AsSe2Cu stoichiometry exhibited apparent bandgaps near 1.0 eV, open circuit photopotentials as high as 600 mV under white light, and, conversion efficiencies (at 500 nm) of 0.01-0.5% for a range of oxidants. In all cases p-type semiconduction dominates. Attempts to synthesize and then compare polycrystalline AsSe2Cu's photoelectrochemical response to the glass are described. The latter so far appears to have generally superior properties for solar energy conversion.
