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
High-performance electronics using dense, perfectly aligned arrays of single-walled carbon nanotubes
Seong Jun Kang,Coskun Kocabas,Taner Ozel,Moonsub Shim,N. Pimparkar,Muhammad A. Alam,Slava V. Rotkin,John A. Rogers +7 more
TL;DR: Dense, perfectly aligned arrays of long, perfectly linear SWNTs are reported as an effective thin-film semiconductor suitable for integration into transistors and other classes of electronic devices, representing a route to large-scale integrated nanotube electronics.
PatentDOI
Medium scale carbon nanotube thin film integrated circuits on flexible plastic substrates
TL;DR: In this paper, a patterned layer of randomly oriented or partially aligned carbon nanotubes, such as one or more interconnected SWNT networks, is used to provide a semiconductor channel exhibiting improved electronic properties relative to conventional nanotube-based electronic systems.
Journal ArticleDOI
A comprehensive model of PMOS NBTI degradation
TL;DR: A comprehensive model for NBTI phenomena within the framework of the standard reaction–diffusion model is constructed and it is demonstrated how to solve the reaction-diffusion equations in a way that emphasizes the physical aspects of the degradation process and allows easy generalization of the existing work.
