TL;DR: In this paper, a diketopyrrolopyrrole-based small bandgap polymer (DPPT-TT) with high mobility is introduced as an additive to D-A1-D-A2 type thieno[3,4-b]thiophene-based random copolymer (P3):(6,6)-phenyl-C70-butyric acid methyl ester (PC71BM) polymer solar cells (PSCs) were improved from 615% to 830% with the addition of 05% DPPT
Journal ArticleDOI
Self-doping n-type polymer as a cathode interface layer enables efficient organic solar cells by increasing built-in electric field and boosting interface contact
Yufei Wang,Zezhou Liang,Xiaoming Li,Jicheng Qin,Meiling Ren,Chunyan Yang,Xichang Bao,Yangjun Xia,Jianfeng Li +8 more
TL;DR: In this paper, a self-doping polymer cathode interface material for organic solar cells was synthesized by incorporating benzotriazole (BTA) as an electron-deficient group and a fluorene containing an amino group.
Journal ArticleDOI
Enhanced Organic Photovoltaic Performance through Modulating Vertical Composition Distribution and Promoting Crystallinity of the Photoactive Layer by Diphenyl Sulfide Additives.
Jianfeng Li,Yufei Wang,Zezhou Liang,Zezhou Liang,Ningning Wang,Junfeng Tong,Chunming Yang,Xichang Bao,Xichang Bao,Yangjun Xia +9 more
TL;DR: DPS could not only modulate the vertical composition distribution but also promote the ordered molecular packing of the photoactive layer, thus effectively improving exciton dissociation, charge transport, and collection, and thus exhibit an excellent power conversion efficiency after using 3% DPS additive.
