摘要

Organic solar cells (OSCs) are promising to access flexible,light weight and semi-transparent photovoltaic devices by low-cost solution fabrication.Recently,the fused-ring non-fullerene acceptors play an important role in promoting the research progress of the OSCs.The power conversion efficiencies (PCEs) have been rapidly boosted to over 14％ in single junction OSCs with the development of new non-fullerene acceptors and the related devices [1-3].Although the PCEs of OSCs are still inferior to their inorganic counterparts,further improvement of the PCEs could be expected by the development of new photovoltaic materials.
