Photoinduced degradation in polymer solar cells is the most challenging issue to be solved because solar cells are required to operate under illumination, but is still not fully understood. In this study, the photoinduced degradation mechanism in P3HT/ICBA solar cells is discussed on the basis of various spectroscopic analyses, device characteristics, and DFT calculations.
