Using the Kubo-Greenwood formula in the approximation of Davis-Mott, the region of exponential absorption of amorphous semiconductors has been theoretically investigated. Analytical expressions for partial absorption spectra for the region of exponential absorption are obtained from two different representations of the Kubo-Greenwood formula. These results showed that of three partial spectra in the region of exponential absorption, the spectra determined correspondingly by electronic transitions from the tail of the valence band to the tail of the conduction band are played the main role.
