“Background Polymer solar cells (PSCs)

have gained great interest because of their low cost, flexibility, and abundant availability [1–7]. So far, the high power conversion efficiency (PCE) of PSCs is achieved by bulk heterojunction (BHJ) PSCs composed of electron-donating polymers and electron-accepting fullerides [8]. Although significant progress has been made on the improvement of the PCE of PSCs in recent years, the efficiency of the PSCs is still lower than their inorganic counterparts, such as silicon and CIGS. The main factors limiting the efficiency of the PSCs are the low light absorption efficiency due to the narrow absorption band of the absorption spectra of the polymers and the charge recombination in the devices due to the low charge transport efficiency in the electron-donating and electron-accepting materials [9].
