The kinetics of the photoresponse of microwave photoconductivity (9 GHz, TE101-type cavity) on excitation by laser light pulses with a wavelength of 337 nm and a duration of 8 ns in copper-deficient Cu1 –x(In0.7Ga0.3)Se2 (CIGS) (0 < x ≤ 0.4) solid solutions with the chalcopyrite structure is investigated in a wide light intensity range. With an increase in the laser radiation density to ~5 × 1014 photon/cm2 per pulse, the photoresponse acquires, along with the previously revealed skin effect, the effect of the filling of traps created by VCu vacancies and Cu+2 · VCu defect associates, the concentration of which increases with a decrease in x in the CIGS formula.
