摘要：

Metal organic vapour deposition (MOCVD) was employed to deposit polycrystalline CuGaSe2 films and solar cells on glass. Deposition temperature was varied between 570 degreesC and 450 degreesC. Continuous CuGaSe2 films were obtained at a deposition temperature of 450 degreesC. Even at this low deposition temperatures the photoluminescence (PL) of the films is dominated by near band gap emission. Depending on the composition the PL spectra are dominated by different donor acceptor pair transitions. Solar cells are processed from these 400nm thick films and the compositional dependence of the photovoltaic parameters is discussed, especially the increase of the open circuit voltage up to 821mV under 100mW/cm(2) AM1.5 with increasing Ga content.
