摘要

In the last three years,polymer solar cells (PSCs) based on ntype organic semiconductor (n-OS) acceptor have become the focus of attention and made great progress.In 2017,the power conversion efficiencies (PCEs) have been boosted to ～13％ for PSCs with single-junction and ～14％ for PSCs with double-junctions.However,the optimized active layer thickness and device area of the high efficiency PSCs are usually limited to ～100 nm and ～0.2 cm2 respectively,which makes the large area fabrication of PSCs very difficult.
