Effect of Heat Treatment on the Crystal Structure and Optical Band Gap of Cigs Thin Films

Abstract:

Article Preview

The CIGS thin films were prepared on ordinary soda lime glass substrates by pulsed laser deposition (PLD). The XRD and UV-visible spectrophotometer has been determined. The influence of different heat treatment temperature on crystal structure and optical properties has been studied. The results shows that heat treatment at 450°C, the films along the (112) plane preferential grow. The thin film’s structure is integrity, the film is in best crystallization conditions, band gap is 1.35eV and the film has a high visible light absorption efficiency.
