Journal ArticleDOI
Aggregation and morphology control enables multiple cases of high-efficiency polymer solar cells.
Yuhang Liu,Jingbo Zhao,Zhengke Li,Cheng Mu,Wei Ma,Huawei Hu,Kui Jiang,Haoran Lin,Harald Ade,He Yan +9 more
TL;DR: The uncovered aggregation and design rules yield three high-efficiency (>10%) donor polymers and will allow further synthetic advances and matching of both the polymer and fullerene materials, potentially leading to significantly improved performance and increased design flexibility.
Journal ArticleDOI
A high-mobility electron-transporting polymer for printed transistors
He Yan,Zhihua Chen,Yan Zheng,Chris Newman,Jordan R. Quinn,Florian Dötz,Marcel Kastler,Antonio Facchetti +7 more
TL;DR: A highly soluble and printable n-channel polymer exhibiting unprecedented OTFT characteristics under ambient conditions in combination with Au contacts and various polymeric dielectrics is reported and all-printed polymeric complementary inverters have been demonstrated.
Journal ArticleDOI
Non-fullerene acceptors for organic solar cells
TL;DR: Non-fullerene acceptors (NFAs) are currently a major focus of research in the development of bulk-heterojunction organic solar cells (OSCs) as mentioned in this paper.
Journal ArticleDOI
Nonfullerene Acceptor Molecules for Bulk Heterojunction Organic Solar Cells
Guangye Zhang,Jingbo Zhao,Philip C. Y. Chow,Kui Jiang,Jianquan Zhang,Zonglong Zhu,Jie Zhang,Fei Huang,He Yan,He Yan +9 more
TL;DR: Progress is summarized, aiming to describe the molecular design strategy, to provide insight into the structure-property relationship, and to highlight the challenges the field is facing, with emphasis placed on most recent nonfullerene acceptors that demonstrated top-of-the-line photovoltaic performances.
Journal ArticleDOI
Non-fullerene acceptors with branched side chains and improved molecular packing to exceed 18% efficiency in organic solar cells
Chao Li,Jiadong Zhou,Jiali Song,Jinqiu Xu,Huotian Zhang,Xuning Zhang,Jing Guo,Lei Zhu,Donghui Wei,Guangchao Han,Jie Min,Yuan Zhang,Zengqi Xie,Yuanping Yi,He Yan,Feng Gao,Feng Liu,Yanming Sun +17 more
TL;DR: Li et al. as discussed by the authors showed that branched alkyl chains in non-fullerene acceptors allow favorable morphology in the active layer, enabling a certified device efficiency of 17.32% with a fill factor of 81.5% for single-junction organic solar cells.
