✦ Synopsis

n-Type CuInSe2 thin films obtained by electrodeposition from a chloride bath containing SeO2 and annealed at different temperatures in N2 plus either 5% H2 or a few parts per million 02 were investigated to discover their photoelectrochemical and electrolyte electroreflectance behaviour. The fundamental parameters of the thin film-polysulphlde electrolyte junction were determined and the performance and stability of the films were examined in photoelectrochemical cells. Finally, a point-by-point surface investigation with both a white light spot and a thin laser beam was performed, showing the nonuniform photoelectrochemical and electrolyte electroreflectance response of the films which could be related to inhomogeneous dopant distribution.
