Abstract

CuInSe2 thin films were electrodeposited potentiostatically from acidic aqueous solutions containing CuCl, InCl3 and SeO2. SCN- ions were used as complexing agents for Cu+ ions in order to shift their reduction potentials inthe negative direction. Different deposition solutions and post-depositiontreatments were compared. The films were characterized by means of energy dispersive X-ray spectrometry, scanning electron microscopy, X-ray diffraction, time-of-flight elastic recoil detection analysis, electrochemical quartz crystal microbalance, cyclic photovoltammetry and photoelectrochemical measurements. The as-deposited films were found to be p-type. The photoactivity was lost after heat treatment, but etching in 0.5 M KCN regenerated it rapidly.
