Journal ArticleDOI
High-Efficiency and Color Stable Blue-Light-Emitting Polymers and Devices†
TL;DR: In this paper, the palladium-catalyzed Suzuki coupling reaction was used to synthesize a blue-light emitting copolymer with an ultraviolet-blue-light (UV-bluelight) emitting host and a blue light emitting component.
Journal ArticleDOI
Fluoroalkyl-substituted fullerene/perovskite heterojunction for efficient and ambient stable perovskite solar cells
Xiao Liu,Xiao Liu,Francis Lin,Chu-Chen Chueh,Qi Chen,Ting Zhao,Po-Wei Liang,Zonglong Zhu,Ye Sun,Alex K.-Y. Jen +9 more
TL;DR: In this article, the authors investigated the feasibility of using a fluoroalkyl-substituted fullerene/perovskite heterojunction (f-FPHJ) to realize efficient and ambient stable perovskitic solar cells (PVSCs).
Journal ArticleDOI
Highly crystalline Zn2SnO4 nanoparticles as efficient electron-transporting layers toward stable inverted and flexible conventional perovskite solar cells
TL;DR: In this article, a facile hydrothermal method was used to prepare crystalline Zn2SnO4 nanoparticles and applied them as an efficient electron-transporting layer (ETL) via a simple room-temperature solution process for perovskite solar cells (PVSCs).
