摘要：
Sputtering deposited CuInSe2 films are of potential important as absorber material in thin-film solar cells as long as we can optimize the annealing process to enhance their optical properties. The aim of the present study is to find the phase transformation mechanism and predict the enhanced optical behaviour of CuInSe2 films as a result of annealing processes. The results show that low-temperature annealing processes not exceeding 250 degrees C can produce regrown and recrystallised CuInSe2 phases to enhance the conversion efficiency of CuInSe2 solar cells. High-temperature annealing processes (at 350 and 400 degrees C) are found to be vital for the transformation from the CuInSe2 phase to CuSe2/Cu2-xSe and InSex/In2Se3 structures. Finally, three selenization models related to the selenisation of the annealing processes are proposed.
