摘要
<正>Organic solar cells (OSCs) based on bulk heterojunction, consisting of a polymer donor and a small molecular acceptor (SMA) represent a promising photovoltaic technology due to their prospect in producing large-area modules via low-cost roll-to-roll processing [1]. This field has experienced three stages according to the type of electron acceptors. Prior to 2015, the electron acceptors
