Photoelectrochemical cells based on n-GaP/n-GaAs/sub 0.4/P/sub 0.6/ strained-layer superlattice (SLS) electrodes have been stabilized against photocorrosion in an aqueous (di) telluride electrolyte, and show monochromatic optical to electrical energy conversion efficiencies of a few percent. The near-band-gap photoluminescence (PL) of the SLS electrodes exhibits field-induced quenching in rough accord with a dead-layer model. Electroluminescence (EL) is observed when the SLS's are used as cathodes in a formamide/Na/sub 2/S/sub 2/O/sub 8/ electrolyte. The EL and PL spectral distributions are similar.
