## 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 10โ€“300 K. The logarithmic variation of the absorption coefficient with photon energy observed in both compounds just below the fundamental abs
