Abstract :
Evaporated Cu-In layers have been selenized, and the morphology of the resulting CuInSe2, (CIS) films has been compared with that of the electrodeposited selenized CIS layers. The evaporation process causes considerable alloying between the Cu and In films and reduces the grain size of the selenized material. Close to 11% efficiency has been demonstrated for solar cells made on selenized Cu-In alloy films
