Organic photovoltaics (OPVs) have become a timely research topic for their advantages of light weight,low cost,low toxicity,environmental adaptability,flexibility,and large-area manufacture,especially after non-fullerene acceptor ITIC reported in 2015.The highest power conversion efficiency (PCE) is currently above 18％ for OPV.However,there are still imparities in the efficiency of OPVs when compared with silicon-based photovoltaics,as well as in their shelf life.Compared with inorganic-based photovoltaics,the efficiency of large-area OPVs is lower and the life time of OPVs is shorter.Therefore,such inferior performance of large-area OPVs restricts the commercial development.Based on these constraints,this paper reviews the research work regarding OPVs into three aspects:stability,encapsulation technology,and recent large-area preparation tech-nologies.

中生代以来,华北克拉通岩石圈发生大规模减薄,岩石圈地幔的物理、化学性质发生显著改变,这一过程通常被称为华北克拉通破坏.目前在华北克拉通东部大规模发育的岩浆岩是岩石圈深部减薄过程在浅部的重要响应,也是克拉通破坏在浅部的直接表现.岩体侵位机制和侵位过程与大地构造背景密切相关,并记录同期区域大地构造信息.15年来,通过对华北克拉通东部不同岩浆发育阶段(晚三叠世、早侏罗世、晚侏罗世、早白垩世早期及早白垩世晚期)22个花岗岩体开展磁化率各向异性(AMS)的研究,反演岩体的就位过程;结合早白垩世早期广泛发育的变质核杂
