## Abstract Cu(In,Ga)Se~2~(CIGS) films were characterized by timeβresolved photoluminescence (TRPL) on performances of solar cells. Open circuit voltage and efficiency of the solar cells increased with increasing the TRPL lifetimes meausred at 77 K and room temperature. The results at 77 K show tha
