To enhance the light harvesting of polymer solar cells (PSCs), amphipathic Al core and PPh3 protective shell (Al@PPh3) nanoparticles (NPs) synthesized by a simple and facile wet chemical process are incorporated into the anode buffer layer of the PTB7:PC71BM blend PSCs. The optimized power conversion efficiency (PCE) of 6.29% is achieved, which is enhanced about 20% compared with the pristine device. It is attributed to the localised surface plasmon resonance (LSPR) effects of Al@PPh3 NPs incorporated in the buffer layer and the light absorption of devices is enhanced.
