摘要
CdS thin film was used as a suitable window layer for CdS/Cd Te solar cell, and the properties of CdS thin films deposited by pulsed laser deposition（PLD）, chemical bath deposition（CBD） and magnetron sputtering（MS） were reported. The experimental results show that the transmittances of PLD-Cd S thin films are about 85% and the band gaps are about 2.38-2.42 e V. SEM results show that the surface of PLD-Cd S thin film is much more compact and uniform. PLD is more suitable to prepare the Cd S thin films than CBD and MS. Based on the thorough study, by using totally PLD technique, the FTO/PLD-Cd S（150 nm）/CSS-Cd Te solar cell（0.0707 cm^2） can be prepared with an efficiency of 10.475%.
