Fast charge separation in a non-fullerene organic solar cell with a small driving force
Jing Liu,Shangshang Chen,Deping Qian,Bhoj Gautam,Guofang Yang,Guofang Yang,Jingbo Zhao,Jonas Bergqvist,Fengling Zhang,Wei Ma,Harald Ade,Olle Inganäs,Kenan Gundogdu,Feng Gao,He Henry Yan +14 more
TL;DR: In this article, fast and efficient charge separation is essential to achieve high power conversion efficiency in organic solar cells (OSCs), and in state-of-the-art OSCs, this is usually achieved by a significant driv
Journal ArticleDOI

Semi-Transparent Tandem Organic Solar Cells with 90% Internal Quantum Efficiency
Zheng Tang,Zandra George,Zaifei Ma,Jonas Bergqvist,Kristofer Tvingstedt,Koen Vandewal,Ergang Wang,L. Mattias Andersson,Mats Andersson,Fengling Zhang,Olle Inganäs +10 more
TL;DR: In this article, a semi-transparent (ST) organic solar cells with potential application as power generating windows are studied, where an amphiphilic conjugated polymer PFPA-1 modified ITO coated glass substrate is employed as the ohmic electron collecting cathode and PEDOT:PSS PH1000 as the hole collecting anode.
