Journal ArticleDOI
High-efficiency solution-processed perovskite solar cells with millimeter-scale grains
Wanyi Nie,Hsinhan Tsai,Reza Asadpour,Jean-Christophe Blancon,Amanda Neukirch,Gautam Gupta,Jared Crochet,Manish Chhowalla,Sergei Tretiak,Muhammad A. Alam,Hsing-Lin Wang,Aditya D. Mohite +11 more
TL;DR: A solution-based hot-casting technique is demonstrated to grow continuous, pinhole-free thin films of organometallic perovskites with millimeter-scale crystalline grains that are applicable to several other material systems plagued by polydispersity, defects, and grain boundary recombination in solution-processed thin films.
Journal ArticleDOI
High-efficiency two-dimensional Ruddlesden–Popper perovskite solar cells
Hsinhan Tsai,Hsinhan Tsai,Wanyi Nie,Jean-Christophe Blancon,Constantinos C. Stoumpos,Reza Asadpour,Boris Harutyunyan,Amanda Neukirch,Rafael Verduzco,Jared Crochet,Sergei Tretiak,Laurent Pedesseau,Jacky Even,Muhammad A. Alam,Gautam Gupta,Jun Lou,Pulickel M. Ajayan,Michael J. Bedzyk,Mercouri G. Kanatzidis,Aditya D. Mohite +19 more
TL;DR: Thin films of near-single-crystalline quality are produced, in which the crystallographic planes of the inorganic perovskite component have a strongly preferential out-of-plane alignment with respect to the contacts in planar solar cells to facilitate efficient charge transport.
Journal ArticleDOI
Light-activated photocurrent degradation and self-healing in perovskite solar cells
Wanyi Nie,Jean-Christophe Blancon,Amanda Neukirch,Kannatassen Appavoo,Hsinhan Tsai,Manish Chhowalla,Muhammad A. Alam,Matthew Y. Sfeir,Claudine Katan,Jacky Even,Sergei Tretiak,Jared Crochet,Gautam Gupta,Aditya D. Mohite +13 more
TL;DR: It is shown that the slow photocurrent degradation in thin-film photovoltaic devices is due to the formation of light-activated meta-stable deep-level trap states, and the creation of small polaronic states involving localized cooperative lattice strain and molecular orientations emerges as a credible microscopic mechanism requiring further detailed studies.
Journal ArticleDOI
Scaling law for excitons in 2D perovskite quantum wells.
Jean-Christophe Blancon,Andreas V. Stier,Hsinhan Tsai,Hsinhan Tsai,Wanyi Nie,Constantinos C. Stoumpos,Boubacar Traore,Laurent Pedesseau,Mikael Kepenekian,Fumiya Katsutani,G. T. Noe,Junichiro Kono,Sergei Tretiak,Scott A. Crooker,Claudine Katan,Mercouri G. Kanatzidis,Jared Crochet,Jacky Even,Aditya D. Mohite,Aditya D. Mohite +19 more
TL;DR: A general scaling law is proposed to determine the binding energy of excitons in perovskite quantum wells of any layer thickness to solve the fundamental questions concerning the nature of optical resonances and their scaling with quantum well thickness.
Journal ArticleDOI
Polaron Stabilization by Cooperative Lattice Distortion and Cation Rotations in Hybrid Perovskite Materials.
Amanda Neukirch,Wanyi Nie,Jean-Christophe Blancon,Kannatassen Appavoo,Hsinhan Tsai,Matthew Y. Sfeir,Claudine Katan,Laurent Pedesseau,Jacky Even,Jared Crochet,Gautam Gupta,Aditya D. Mohite,Sergei Tretiak +12 more
TL;DR: An in-depth computational study of small polaron formation, electronic structure, charge density, and reorganization energies using both periodic boundary conditions and isolated structures suggests formamidinium and cesium based crystals and alloys are potentially better materials for solar cell and other optoelectronic applications.
