【 摘 要 】
The preparation of (Cu,Se)(In,N) thin films by r.f magnetron sputtering technique opens an interesting research area with potential application in solar cells. In this work, we presented a systematic study of growth and characterization of CuSe thin films and layers of CuSe/In deposited on glass substrates by varying the power r.f source and substrate temperature. The effects of experimental parameters on morphology and the optical properties of the films were investigated by XRD, UV-Visible and SEM. The results show that the samples are polycrystalline with a hexagonal structure for the CuSe films, and tetragonal structure for the CuSe/In layers. SEM images took on the surface of the films, showed a change in their morphology, evidencing a strong dependence of the experimental parameters. From UV-Visible measurements determine the bandgap and the optical behaviour of the films.【 预 览 】
