Abstract

Photoelectron spectroscopy and admittance spectroscopy were used to analyze Cu(In,Ga)Se₂ (CIGS) based thin films and heterojunction solar cells based on chemical oxygenation and post-deposition air-annealing effects. The effect of CIGS surface chemistry on the electronic structure of the heterojunction solar cells and the influence on the CIGS layer of oxygenation-induced Cu redistribution were analyzed. Results showed that charge redistribution and compensation of the effective acceptor density can be achieved in the bulk of the absorber.
