CuIn3Se5 films have been deposited with Na2S on Coning 7059 glass substrates by the two-stage co-evaporation method. Stoichiometric CuIn3Se5 films with p-type conduction with the resistivities of 106 Ω · cm range were obtained by our sodium control technique. Enhanced grain growth and preferred (112) orientation were also clearly observed with sodium incorporation; the same effect that has been reported for chalcopyrite CuInSe2 thin films. The effects of sodium in these films have been investigated by comparing the electrical and optical properties of CuIn3Se5 films with and without the Na incorporation. A correlation between the photoluminescence spectra and the resistivity or conduction type of the CuIn3Se5 films was found, suggesting a reduction in compensation due to the suppression of donor-type defects by the presence of Na.
