The controversial issue of a source for the fill factor losses in Cu(In,Ga)Se-2-based solar cells observed under red light is discussed. Experimental evidence is presented that removal of the fill factor loss by blue light is accompanied by a decrease in capacitance. Similar kinetics for both effects are observed. This effect is demonstrated not only on CdS-buffered devices but also on Zn(O,S)- and In2S3-buffered cells. The explanation, supported by simulations, is based on a model of a reduction of the p+ layer by holes photogenerated in the buffer. This effect might be differentiated from the effect of a photosensitive secondary barrier in the buffer-window part of the junction by a sign of the capacitance change under blue light.
