Single quantum wells (SQWs) of GaAs/Al_xGa_1-xAs have been investigated as photoelectrodes in photoelectrochemical cells.Structured photocurrent spectra for well widths of 50Å and 100Å SQWs were obtained in nonaqueous solution.The dependence of structured photocurrent spectra on electrode potential were exhibited.The quantum yield was higher in SQW with 100Å well compared to 50Å well.
