Photovoltaic and photoelectrochemical properties of hydrogenated amorphous silicon(a Si:H) films were investigated by surface photovoltaic spectrometry and PEC method.The results show that the photovoltage spectra(SPS) of three type a Si:H films are difference,which highly depend on the doping conditions.Based on the spectra,the valence band and conduction band of intrinsic a Si:H film were calculated.
