%X It is found that there are two intrinsic electric field regions in samples of InyGa1-yAs/GaAssuperlattices on InxGa1-xAs buffer layer.The electric field in these two regions, with one locating atthe surface and another locating at the interface between the InyGa1-yAs/GaAs superlattices and the InxGa1-x As buffer layer,has contrary direction each other. Based on this model,we can give a goodexplanation to the photovoltaic spectra of these samples.
