Abstract
CuInSe2 thin films were successfully deposited on SFO (SnO2: F) glass substrates by magnetron RF-sputtering then annealed in vacuum at different temperatures (200, 250, 350 and 400 ). The effect of the annealing temperatures on the film structures, morphologies, and properties was investigated in detail. The results show that the CIS films with the room temperature by magnetron RF-sputtering was found to exhibit not amorphous but chalcopyrite phase structure. At the higher annealing temperatures the crystallinity and grain size were enhanced. Moreover, the 200 annealed CIS film shows better electrical behavior than other films. Finally, the optical measurements suggest that the optical property increased for annealing temperatures more than 200.
