TL;DR: Inverted solar cells with active layer thicknesses ranging from 100 to 440 nm display PCEs exceeding 6.5%, with the highest efficiency of 7.64% achieved with a 230 nm thick active layer.
Journal ArticleDOI
Achieving a Significantly Increased Efficiency in Nondoped Pure Blue Fluorescent OLED: A Quasi-Equivalent Hybridized Excited State
Shitong Zhang,Liang Yao,Qiming Peng,Weijun Li,Yuyu Pan,Ran Xiao,Yu Gao,Cheng Gu,Zhiming Wang,Ping Lu,Feng Li,Shi-Jian Su,Bing Yang,Yuguang Ma +13 more
TL;DR: In this article, a fine excited state modulation was carried out to reach a golden combination of the high PL efficiency locally emissive (LE) component and the high exciton utilizing charge transfer (CT) component in one excited state.
Journal ArticleDOI
Recent progress in hot exciton materials for organic light-emitting diodes
TL;DR: A comprehensive review of the recent progress in hot exciton materials, which can effectively harness the non-radiative triplet excitons via reverse intersystem crossing (RISC) from high-lying triplet states to singlet states.
Journal ArticleDOI
Highly Efficient Blue Fluorescent OLEDs Based on Upper Level Triplet–Singlet Intersystem Crossing
Yuwei Xu,Xiaoming Liang,Xuehong Zhou,Peisen Yuan,Peisen Yuan,Jiadong Zhou,Cong Wang,Binbin Li,Dehua Hu,Xianfeng Qiao,Xiao-Fang Jiang,Linlin Liu,Shi-Jian Su,Dongge Ma,Yuguang Ma +14 more
TL;DR: Results reveal that the "hot exciton" path is a promising way to exploit high efficient, stable fluorescent emitters, especially for the pure-blue and deep-blue fluorescent organic light-emitting devices.
Journal ArticleDOI
11% Efficient Ternary Organic Solar Cells with High Composition Tolerance via Integrated Near-IR Sensitization and Interface Engineering.
