A Non-fullerene Acceptor with Enhanced Intermolecular π-Core Interaction for High-Performance Organic Solar Cells.
TL;DR: The face-to-face π-core interaction induced by benzo[2,1,3]thiadiazole S-N containing moieties plays a significant role in governing the molecular geometries and unique packing of Y6 and CH1007 to ensure their superior charge-transporting properties.
Journal ArticleDOI
Two-Dimensional Perovskite Solar Cells with 14.1% Power Conversion Efficiency and 0.68% External Radiative Efficiency
TL;DR: In this article, a quasi-2D perovskite (PEA)2(MA)4Pb5I16-based optoelectronic device was processed with NH4SCN and NH4Cl additives, showing a stabilized photovoltaic power conversion efficiency as high as 14.1% (average value 12.9 ± 0.8%).

CsPbBr3 Perovskite Quantum Dot Vertical Cavity Lasers with Low Threshold and High Stability
Chun-Ying Huang,Chen Zou,Chenyi Mao,Kathryn L. Corp,Yung Chi Yao,Ya Ju Lee,Cody W. Schlenker,Alex K.-Y. Jen,Lih Y. Lin +8 more
TL;DR: In this paper, an ultralow lasing threshold (0.39 μJ/cm2) was obtained for a hybrid vertical cavity surface emitting laser (VCSEL) structure consisting of a CsPbBr3 QD thin film and two highly reflective distributed Bragg reflectors (DBRs).
