Preparation of CuInSe₂ Thin Films by the Pulse-Plated Electrodeposition

Abstract

CuInSe 2 thin films have been prepared by the pulse-plated electrodeposition from aqueous solutions containing CuCl 2 , InCl 3 and SeO 2 . The influence of the square pulse cathode potential on the film compositions, crystallinity and surface morphology has been studied. Homogeneous single phase CuInSe 2 films with smooth surfaces have been obtained at a pulse potential of -0.8V vs the saturated calomel electrode (SCE), a duty cycle θ of 33%, and annealing treatment.
