Journal ArticleDOI
High-Efficiency Perovskite Solar Cells.
TL;DR: This review summarizes the fundamentals behind the optoelectronic properties of perovskite materials, as well as the important approaches to fabricating high-efficiency perovSKite solar cells, and possible next-generation strategies for enhancing the PCE over the Shockley-Queisser limit are discussed.
Journal ArticleDOI
Self-formed grain boundary healing layer for highly efficient CH 3 NH 3 PbI 3 perovskite solar cells
Dae-Yong Son,Jin-Wook Lee,Y. Choi,In Hyuk Jang,Seonhee Lee,Pil J. Yoo,Hyunjung Shin,Namyoung Ahn,Mansoo Choi,Dongho Kim,Nam-Gyu Park +10 more
TL;DR: In this article, the grain boundaries in thin-film perovskite solar cells are passedivated by using excess CH3NH3I in the precursor solution, achieving an average power conversion efficiency of 20.1% over 50 cells (best cell at 20.4%).
Journal ArticleDOI
Universal Approach toward Hysteresis-Free Perovskite Solar Cell via Defect Engineering
TL;DR: A universal approach for hysteresis-free perovskite solar cells via defect engineering via KI doping and a series of experiments with alkali metal iodides of LiI, NaI, KI, RbI and CsI reveals that potassium ion is the right element for Hysteres is-freeperovskites.
Journal ArticleDOI
Controlling the Thickness of the Surface Oxide Layer on Cu Nanoparticles for the Fabrication of Conductive Structures by Ink‐Jet Printing
Sunho Jeong,Kyoohee Woo,Dongjo Kim,Soon-Kwon Lim,Jang Sub Kim,Hyunjung Shin,Younan Xia,Younan Xia,Jooho Moon +8 more
TL;DR: In this paper, the surface oxide layer on Cu nanoparticles synthesized in ambient atmosphere was minimized by adjusting the molecular weight of poly(N-vinylpyrrolidone) capping molecules, as confirmed by high resolution transmission electron microscopy and X-ray photoelectron spectroscopy analyses.
Journal ArticleDOI
Random Circuit Breaker Network Model for Unipolar Resistance Switching
Seung Chul Chae,Jae Sung Lee,Sejin Kim,Shinbuhm Lee,Seo Hyoung Chang,Chunli Liu,Byungnam Kahng,Hyunjung Shin,Dong-Wook Kim,Chang Uk Jung,Sunae Seo,Sunae Seo,Myoung-Jae Lee,Myoung-Jae Lee,Tae Won Noh +14 more
TL;DR: Noh et al. as discussed by the authors proposed a percolation model based on a network of circuit breakers with two switchable metastable states to explain the reversible resistance switching behavior in polycrystalline TiO2 thin capacitors.
