Interface quality plays a key role in solar cell applications. recombination at the front and rear surfaces, which determine this quality, have significant effects on open circuit voltage fill factor values. In work, several surface treatments were applied Cu(In,Ga)Se 2 (CIGS) surfaces to improve interface quality. Besides, passivation layer implementation was investigated reduce between buffer absorber layers.
