<正>The exquisite design and persistent development of fused-ring-acceptor-unit-based copolymer donors and Yseries nonfullerene acceptors(NFAs) have pushed the power conversion efficiencies(PCEs) for organic solar cells onto the18% level[1-21]. Our group invented copolymer donors D18 and D18-Cl[2, 3]. D18:Y6, D18-Cl:N3 and D18:N3 solar cells have delivered outstanding PCEs of 18.22%, 18.13% and18.56%, respectively[2-4]. Ternary solar cells based on a polymer donor, a NFA and a fullerene acceptor show great potential since they combine good light-harvesting capability of NFA and good electron-mobility of fullerene[5].
