TL;DR: The results have demonstrated that NI based planar small molecules are potential acceptors for WBG polymer based OSCs.
Journal ArticleDOI
4-Alkyl-3,5-difluorophenyl-Substituted Benzodithiophene-Based Wide Band Gap Polymers for High-Efficiency Polymer Solar Cells
TL;DR: PSCs with the blend of PTFBDT-BZS:PC71BM (1:2, by weight) as the active layer fabricated without using any processing additive and any postannealing treatment showed power conversion efficiency (PCE) of 8.24% with an open circuit voltage (Voc) of 0.89 V, a short circuit current (Jsc) of 12.67 mA/cm(2), and a fill factor (FF).
Journal ArticleDOI
Triindole-cored star-shaped molecules for organic solar cells
TL;DR: In this article, two triindole-cored star-shaped molecules SM-1 and SM-2 have been designed and synthesized, and their optical, electrochemical, thermal, transport and photovoltaic properties have been investigated in detail.
Journal ArticleDOI
A nonfullerene acceptor for wide band gap polymer based organic solar cells
Jicheng Zhang,Xuejuan Zhang,Guangwu Li,Hongmei Xiao,Wenhua Li,Sufei Xie,Cuihong Li,Zhishan Bo +7 more
TL;DR: A new 1,8-naphthalimide based planar small molecular acceptor and two benzothiadiazole based wide band gap (WBG) polymer donors P1 and P2 were synthesized for nonfullerene organic photovoltaic cells (OPVs) and achieved a highly improved PCE.
