We present a new structure to fabricate CIGS thin-film solar cells for better merits. The structure improves cost, conversion efficiency and reduces chemical pollution. The structure includes ZnS/CdS buffer with/without i-ZnO layers on the CIGS absorber. The beat features of η=9.23%, JSC=26.72 mA/cm2 and EQE for the short-wavelength range were improved. The optimal cell could be effectively and eco-friendly applied to commercial production
