Abstract

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.
