The photoelectrochemical behaviour of the multilayer semiconductive electrode (GaAs/Al_xGa_1-xAs)with the structure of N⁺NP and N⁺NPP was studied in Na₂SO₄ solution.Compared with single kind semiconductor electrode,the commposite one has broader photoresponse spectral region and larger open-circuit photovoltage,consequently gives higher solar energy conversion efficiency.
