A Vinylene-Bridged Perylenediimide-Based Polymeric Acceptor Enabling Efficient All-Polymer Solar Cells Processed under Ambient Conditions

All-polymer solar cells with 7.57% power conversion efficiency are achieved via a new perylenediimide-based polymeric acceptor. Furthermore, the device processed in ambient air without encapsulation can still reach a high power conversion efficiency (PCE) of 7.49%, which is a significant economic advantage from an industrial processing perspective. These results represent the highest PCE achieved from perylenediimide-based polymers.National Natural Science Foundation of China [51473003]; UNC-GA Research Opportunity Initiative grant; National Basic Research Program of China (973 Program) [2013CB834705]; HK JEBN Limited (Hong Kong); Hong Kong Research Grants Council [T23-407/13-N, N_HKUST623/13]SCI(E)PubMedARTICLEhwade@ncsu.edu; dhzhao@pku.edu.cn; hyan@ust.hk388483-84892
