Alexander J. Gillett,Alberto Privitera,Rishat Dilmurat,Akchheta Karki,Deping Qian,Anton Pershin,Giacomo Londi,William K. Myers,Jaewon Lee,Jun Yuan,Seo-Jin Ko,Moritz Riede,Feng Gao,Guillermo C. Bazan,Akshay Rao,Thuc-Quyen Nguyen,David Beljonne,Richard H. Friend +17 more
TL;DR: In this article, the authors show that the majority of charge recombination at open-circuit proceeds via formation of non-emissive NFA triplet excitons (T1), and they develop a new design to prevent recombination via this nonradiative channel through the engineering of significant hybridisation between the NFA T1 and the spin-triplet charge transfer exciton (3CTE).
