Journal ArticleDOI
Highly Reproducible Perovskite Solar Cells with Average Efficiency of 18.3% and Best Efficiency of 19.7% Fabricated via Lewis Base Adduct of Lead(II) Iodide
TL;DR: High efficiency perovskite solar cells were fabricated reproducibly via Lewis base adduct of lead(II) iodide through interaction between Lewis base DMSO and/or iodide and Lewis acid PbI2 through spin-coating of a DMF solution.
Journal ArticleDOI
Lithium-ion batteries: outlook on present, future, and hybridized technologies
TL;DR: In this article, a review of the present and the future battery technologies on the basis of the working electrode is presented and an account of a stand-alone energy device (off-grid system) that combines an energy harvesting technology with a lithium-ion battery is also provided.
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
Printable organometallic perovskite enables large-area, low-dose X-ray imaging
Yong Churl Kim,Kwang Hee Kim,Dae-Yong Son,Dong-Nyuk Jeong,Ja-Young Seo,Yeong Suk Choi,In Taek Han,Sang Yoon Lee,Nam-Gyu Park +8 more
TL;DR: An all-solution-based perovskite detector could enable low-dose X-ray imaging, and could also be used in photoconductive devices for radiation imaging, sensing and energy harvesting.
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.
