AB  - Recently, Photoacoustic Spectroscopy (PAS) technique has emerged as a valuable tool for the study of materials, like chemical and physical materials, in this study we reports on the optical properties of the photovoltaic material CuInTe<SUB>2</SUB> (CIT) as characterised by Photoacoustic Spectroscopy (PAS). Measured spectra of p-conducting CIT single crystals are given using a high resolution photoacoustic spectrometer of the gas-microphone type. The data is used to evaluate the absorption spectra, the band gap energy and ionisation energies of defects that have been observed in the tail of the spectra. The obtained Results confirm the efficiency of the technique in detecting the non-radiative defects known to dominate the properties of this compound. A discussion on the relation between the composition of the samples and the intrinsic defect chemistry in this compound is also given. Finally, we give a comparison between the results we have obtained and those published in the literature.
