Abstract

The controversial issue of a source of the fill factor losses in CIGS solar cells observed under red light is discussed. The experimental evidences are presented that removal of the fill factor loss by blue light is accompanied by a decrease of capacitance. Similar kinetics of both effects is 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 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.
