Abstract
The processes of photochemical reorganization of deep levels of the photoactive centers in films CdS1-xSex (0 ≤ x ≤ 0.8) prepared onto molybdenum substrates by the method of electrochemical deposition were investigated. It is established that thermal annealing of investigated films in air at Ta=380 ÷400°C for τa=7÷8 min leads to occurrence of new longwavelength maximum in the photosensitivity spectrum at λ=0.95-1.15 μm (depending on the selenium content) which is due to oxygen-containing photoactive centers forming at disintegration of (VCd-Cdi)+ pairs. The mechanism of formation and disintegration of donor-acceptor pairs have been proposed and basic parameters of complex centers formed at thermal annealing were determined by the method of photocapacitance and photoconductivity spectroscopy.
