Journal ArticleDOI
Low trap-state density and long carrier diffusion in organolead trihalide perovskite single crystals
Dong Shi,Valerio Adinolfi,Riccardo Comin,Mingjian Yuan,Erkki Alarousu,Andrei Buin,Yin Chen,Sjoerd Hoogland,Alexander Rothenberger,Khabiboulakh Katsiev,Yaroslav Losovyj,Xin Zhang,Peter A. Dowben,Omar F. Mohammed,Edward H. Sargent,Osman M. Bakr +15 more
TL;DR: An antisolvent vapor-assisted crystallization approach is reported that enables us to create sizable crack-free MAPbX3 single crystals with volumes exceeding 100 cubic millimeters, which enabled a detailed characterization of their optical and charge transport characteristics.
Journal ArticleDOI
Efficient and stable solution-processed planar perovskite solar cells via contact passivation.
Hairen Tan,Ankit Jain,Oleksandr Voznyy,Xinzheng Lan,F. Pelayo García de Arquer,James Z. Fan,Rafael Quintero-Bermudez,Mingjian Yuan,Bo Zhang,Yicheng Zhao,Fengjia Fan,Peicheng Li,Li Na Quan,Yongbiao Zhao,Zheng-Hong Lu,Zhenyu Yang,Sjoerd Hoogland,Edward H. Sargent +17 more
TL;DR: A contact-passivation strategy using chlorine-capped TiO2 colloidal nanocrystal film that mitigates interfacial recombination and improves interface binding in low-temperature planar solar cells is reported.
Journal ArticleDOI
Perovskite energy funnels for efficient light-emitting diodes
Mingjian Yuan,Li Na Quan,Li Na Quan,Riccardo Comin,Grant Walters,Randy P. Sabatini,Oleksandr Voznyy,Sjoerd Hoogland,Yongbiao Zhao,Eric M. Beauregard,Pongsakorn Kanjanaboos,Zheng-Hong Lu,Dong Ha Kim,Edward H. Sargent +13 more
TL;DR: A perovskite mixed material comprising a series of differently quantum-size-tuned grains that funnels photoexcitations to the lowest-bandgap light-emitter in the mixture functions as charge carrier concentrators, ensuring that radiative recombination successfully outcompetes trapping and hence non-radiatives recombination.
Journal ArticleDOI
Ultrasensitive solution-cast quantum dot photodetectors
Gerasimos Konstantatos,Ian A. Howard,Armin Fischer,Sjoerd Hoogland,Jason Paul Clifford,Ethan J. D. Klem,Larissa Levina,Edward H. Sargent +7 more
TL;DR: The tailored selection of absorption onset energy through the quantum size effect, combined with deliberate engineering of the sequence of nanoparticle fusing and surface trap functionalization, underlie the superior performance achieved in this readily fabricated family of devices.
Journal ArticleDOI
Colloidal-quantum-dot photovoltaics using atomic-ligand passivation
Jiang Tang,Kyle W. Kemp,Sjoerd Hoogland,Kwangseob Jeong,Huan Liu,Huan Liu,Larissa Levina,Melissa Furukawa,Xihua Wang,Ratan Debnath,Dongkyu Cha,Kang Wei Chou,Armin Fischer,Aram Amassian,John B. Asbury,Edward H. Sargent +15 more
TL;DR: An atomic ligand strategy is established that makes use of monovalent halide anions to enhance electronic transport and successfully passivate surface defects in PbS CQD films that shows up to 6% solar AM1.5G power-conversion efficiency.
