Surface/Interface Effects by Alkali Postdeposition Treatments of (Ag,Cu)(In,Ga)Se₂ Thin Film Solar Cells.

ABSTRACT: Ag alloying and the introduction of alkali elements through a postdeposition treatment are two approaches to improve the performance of Cu(In,Ga)Se₂ (CIGS) thin film solar cells. In particular, a postdeposition treatment of an alkali metal fluoride of the absorber has shown a beneficial effect on the solar cells performance due to an increase in the open circuit voltage (V _OC) for both (Ag,Cu)(In,Ga)Se₂ (ACIGS) and CIGS based solar cells. Several reasons have been suggested for the improved V _OC in CIGS solar cells including absorber surface and interface effects. Less works investigated how the applied postdeposition treatment influences the ACIGS absorber surface and interface properties and the subsequent buffer layer growth. In
