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

TL;DR: A room-temperature synthesis to produce gelled oxyhydroxides materials with an atomically homogeneous metal distribution that exhibit the lowest overpotential reported at 10 milliamperes per square centimeter in alkaline electrolyte and shows no evidence of degradation after more than 500 hours of operation.
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
Ligand-Stabilized Reduced-Dimensionality Perovskites
Li Na Quan,Li Na Quan,Mingjian Yuan,Riccardo Comin,Oleksandr Voznyy,Eric M. Beauregard,Sjoerd Hoogland,Andrei Buin,Ahmad R. Kirmani,Kui Zhao,Aram Amassian,Dong Ha Kim,Edward H. Sargent +12 more
TL;DR: Reduced-dimensionality (quasi-2D) perovskite films are reported that exhibit improved stability while retaining the high performance of conventional three-dimensionalperovskites, and are achieved by the choice of stoichiometry in materials synthesis.
Journal ArticleDOI
Perovskite–fullerene hybrid materials suppress hysteresis in planar diodes
Jixian Xu,Andrei Buin,Alexander H. Ip,Wei Li,Oleksandr Voznyy,Riccardo Comin,Mingjian Yuan,Seokmin Jeon,Zhijun Ning,Jeffrey J. McDowell,Pongsakorn Kanjanaboos,Jon-Paul Sun,Xinzheng Lan,Li Na Quan,Dong Ha Kim,Ian G. Hill,Peter Maksymovych,Edward H. Sargent +17 more
TL;DR: The first perovskite–PCBM hybrid solid with significantly reduced hysteresis and recombination loss achieved in a single step is reported, and it is posited that PCBM, by tying up both halide-rich antisites and unincorporated halides, reduces electric field-induced anion migration that may give rise to hysteResis and unstable diode behaviour.
