Abstract As the absorber layer in CISe-based solar cell CIGSe thin film was prepared by precursorselenization method. The influences of selenization temperature on compositions, morphologies, phase structures and electronic properties of CIGSe thin films were investigated. The compositions, morphologies and phase structures of CIGSe by means of XRF, SEM, XRD and Raman, respectively were analyzed. Based on Hall Effect the resistivities and minority carrier mobilities of CIGSe were tested. The results show that there are no differences in morphologies and compositions of CIGSe films prepared at 520–560oC. Ordered defect compound (ODC) phase and Cu–Se phase increase with the increasing of selenization temperatures, which increases the concentrations of defect in CIGSes and causes the deterioration of electronic properties of thin film.
