TL;DR: The results lead to a comprehensive picture, where the highly desirable type inversion at the p/n interface in standard chalcopyrite thin-film solar cells is dominated by band bending within the CIGSe absorber rather than the result of Na impurities or an n-type defect phase segregating at the interface.

Applied Physics Letters

TL;DR: In this article, the effects of Ga additions on the electronic and structural properties of CuInSe2 were theoretically studied using a first-principles band structure method, and it was shown that with increasing xGa, the valence band maximum of CIGS decreases slightly, while the conduction band minimum increases significantly.
