Abstract :
CuGaSe2 (CGSe) thin films for photovoltaic applications have been subjected to surface treatments based on In-S by means of chemical vapor deposition. Structural and electronic characterization of as-grown films and processed devices show the effective incorporation of In and S in the near-surface region of CGSe thin films and a positive impact on the solar cell performance.
