Abstract
Polycrystalline CuInSe2 thin films grown by the three-source co-evaporation technique are assessed near their fundamental absorption edge with a high resolution photoacoustic spectrometer of the gas-microphone type. The results are presented for films differing in uniformity, composition and thickness. The effect of heat treatment in various ambients on the properties of these films have also been investigated using in addition to photoacoustic spectroscopy, X-ray diffraction, Rutherford backscattering spectroscopy and scanning electron microscopy.
