The relationship between photostability and dispersed structures of poly(3-hexylthiophene) (P3HT):fullerene films was studied using atomic force microscopy and UV-Vis absorption spectroscopy. The films with higher dispersity showed better photostability. An evaluation method based on UV-Vis absorption spectroscopy was found to be promising to estimate the photostability of the films.
