• a crystal state, additional peaks are observed at a higher wavelength because of the π-π interaction between its polymer chains. Therefore, the P3HT contained in the films of PCBM and ThCBM is in a more crystalline state than that contained in the films of 2-BThCBM (3a) and es-TThCBM (3d), which is
