Journal ArticleDOI
Stable perovskite solar cells with efficiency exceeding 24.8% and 0.3-V voltage loss.
Mingyu Jeong,In Woo Choi,Eun Min Go,Yongjoon Cho,Minjin Kim,Byongkyu Lee,Seonghun Jeong,Yimhyun Jo,Hye Won Choi,Jiyun Lee,Jin-Hyuk Bae,Sang Kyu Kwak,Dong Suk Kim,Changduk Yang +13 more
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
11.4% Efficiency non-fullerene polymer solar cells with trialkylsilyl substituted 2D-conjugated polymer as donor.
Haijun Bin,Liang Gao,Zhi-Guo Zhang,Yankang Yang,Yindong Zhang,Chunfeng Zhang,Chunfeng Zhang,Shanshan Chen,Lingwei Xue,Changduk Yang,Min Xiao,Min Xiao,Yongfang Li,Yongfang Li +13 more
TL;DR: A trialkylsilyl substituted 2D-conjugated polymer with the highest occupied molecular orbital level down-shifted by Si–C bond interaction is developed and indicates that the alkylsilyl substitution is an effective way in designing high performance conjugated polymer photovoltaic materials.
Journal ArticleDOI
Side-Chain Isomerization on an n-type Organic Semiconductor ITIC Acceptor Makes 11.77% High Efficiency Polymer Solar Cells
Yangkang Yang,Zhi-Guo Zhang,Haihun Bin,Shanshan Chen,Liang Gao,Lingwei Xue,Changduk Yang,Yongfang Li,Yongfang Li +8 more
TL;DR: The results indicate that m-ITIC is a promising low bandgap n-OS for the application as an acceptor in PSCs, and the side-chain isomerization could be an easy and convenient way to further improve the photovoltaic performance of the donor and acceptor materials for high efficiency P SCs.
Journal ArticleDOI
Non-Fullerene Polymer Solar Cells Based on Alkylthio and Fluorine Substituted 2D-Conjugated Polymers Reach 9.5% Efficiency
Haijun Bin,Zhi-Guo Zhang,Liang Gao,Shanshan Chen,Lian Zhong,Lingwei Xue,Changduk Yang,Youngfang Li,Youngfang Li +8 more
TL;DR: Three medium bandgap 2D-conjugated bithienyl-benzodithiophene-alt-fluorobenzotriazoleCopolymers J52, J60, and J61 are synthesized for the application as donor in the PSCs with low bandgap n-OS ITIC as acceptor and results indicate that J61 is a promising medium band gap polymer donor in non-fullerene P SCs.
Journal ArticleDOI
