## Abstract We study some physical properties of CuIn~1β__x__~ Ga__~x~__ Se~2~ thinβfilms fabricated by evaporation from elemental sources under various Selenium environments. Specifically, thinβfilms were fabricated under growth conditions such as Se deficiency, near stoichiometry and excess Se du

## 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
In this paper we present results concerning the effect of preparation conditions on the surface chemistry and crystalline phase of Cu(In,Ga)Se 2 (CIGS) thin films grown by a chemical reaction of the precursor species in two and three stage processes. The CIGS samples were studied by X-ray photoelect
