TL;DR: In this paper, the pseudo-halide anion formate (HCOO−) was used to suppress anion-vacancy defects that are present at grain boundaries and at the surface of the perovskite films.
Journal ArticleDOI
Methylammonium Chloride Induces Intermediate Phase Stabilization for Efficient Perovskite Solar Cells
Minjin Kim,Minjin Kim,Gi-Hwan Kim,Tae Kyung Lee,In Woo Choi,Hye Won Choi,Yimhyun Jo,Yung Jin Yoon,Jae Won Kim,Jiyun Lee,Daihong Huh,Heon Lee,Sang Kyu Kwak,Jin Young Kim,Dong Suk Kim +14 more
TL;DR: In this article, the function of methylammonium chloride (MACl) additive in formamidinium lead iodide (FAPbI3)-based perovskite was studied.
Journal ArticleDOI
Stable perovskite solar cells with efficiency exceeding 24.8% and 0.3-V voltage loss.

TL;DR: Two fluorinated isomeric analogs of the well-known hole-transporting material Spiro-OMeTAD are developed and used as HTMs in PSCs and feature high efficiency, open-circuit voltage, and stability of perovskite solar cells.
Journal ArticleDOI
Conformal quantum dot–SnO2 layers as electron transporters for efficient perovskite solar cells
Minjin Kim,Jaeki Jeong,Hai-Zhou Lu,Taemin Lee,Felix Eickemeyer,Yuhang Liu,In Woo Choi,Seunggun Choi,Yim Hyun Jo,Hak-Beom Kim,Sung-In Mo,Youngkwon Kim,Heun Soo Lee,Na Gyeong An,Shin uk Cho,Wolfgang Tress,Shaik M. Zakeeruddin,Anders Hagfeldt,Jin Young Kim,Michael Grätzel,Dong Suk Kim +20 more
TL;DR: Replacing the commonly used mesoporous–titanium dioxide electron transport layer with a thin layer of polyacrylic acid–stabilized tin(IV) oxide quantum dots enhanced light capture and largely suppressed nonradiative recombination at the ETL–perovskite interface, resulting in a certified power conversion efficiency of 25.4% and high operational stability.
Journal ArticleDOI
The hydrothermal synthesis of mesoporous TiO2 with high crystallinity, thermal stability, large surface area, and enhanced photocatalytic activity
Dong Suk Kim,Seung-Yeop Kwak +1 more
TL;DR: In this article, a well-defined spherical mesoporous TiO2 was prepared from a poly(ethylene glycol)-poly(propylene glycol) based triblock copolymer and titanium isopropoxide mixed with 2,4-pentanedione by using a simple sol-gel approach in aqueous solution.
