Paper Abstract

The Cu(In1-xGax)Se2 (CIGS) thin films were prepared by stacked elemental layers (SEL) method via vacuum evaporation. X-ray diffraction (XRD) analysis showed that the films were consisted of chalcopyrite CIGS phase. Scanning electronic microscopy indicated that the film surface was compact and the grain size was about 1μm. It was found that CIGS film with preparation sequence Ga/In/Cu/Se was of best crystalline quality. Besides, adding Ga greatly improved the crystallinity for all sequences compared with CIS films at the same annealing temperature.
