## Abstract Optical absorption spectra of CuIn~5~Se~8~ and CuGa~3~Se~5~ single crystals grown by chemical vapour transport were investigated in the range of 10–300 K. The logarithmic variation of the absorption coefficient with photon energy observed in both compounds just below the fundamental abs
