Researchers develop fused-ring electron acceptor with 3-D exciton and charge transport

Recently, Professor Zhan Xiaowei's group from the College of Engineering at Peking University made progress in non-fullerene acceptors for organic solar cells (OSCs). They developed a new fluorinated fused-ring electron acceptor (FREA) with 3-D stacking and exciton and charge transport (Adv. Mater., DOI: 10.1002/adma.202000645).
