Journal ArticleDOI
Semi-crystalline photovoltaic polymers with efficiency exceeding 9% in a ∼300 nm thick conventional single-cell device
Thanh Luan Nguyen,Hyosung Choi,Seo-Jin Ko,Mohammad Afsar Uddin,Bright Walker,Seungjib Yum,Ji Eun Jeong,Myoung Hee Yun,Tae Joo Shin,Seongyeon Hwang,Jin Young Kim,Han Young Woo +11 more
TL;DR: In this paper, a series of semi-crystalline, low band gap (LBG) polymers and demonstrate the fabrication of highly efficient polymer solar cells (PSCs) in a thick single-cell architecture.
Journal ArticleDOI
Eco-Compatible Solvent-Processed Organic Photovoltaic Cells with Over 16% Efficiency.
Ling Hong,Huifeng Yao,Ziang Wu,Yong Cui,Tao Zhang,Ye Xu,Runnan Yu,Qing Liao,Bowei Gao,Kaihu Xian,Han Young Woo,Ziyi Ge,Jianhui Hou +12 more
TL;DR: The results indicate that the simple modification of the side chain can be used to tune the processability of active layer materials and thus make it more applicable for the mass production with environmentally benign solvents.
Journal ArticleDOI
Achieving Highly Efficient Nonfullerene Organic Solar Cells with Improved Intermolecular Interaction and Open-Circuit Voltage.
Huifeng Yao,Long Ye,Junxian Hou,Bomee Jang,Guangchao Han,Yong Cui,Gregory M. Su,Cheng Wang,Bowei Gao,Runnan Yu,Hao Zhang,Yuanping Yi,Han Young Woo,Harald Ade,Jianhui Hou +14 more
TL;DR: A new acceptor-donor-acceptor-structured nonfullerene acceptor ITCC shows improved electron-transport properties and a high-lying lowest unoccupied molecular orbital level, suggesting that ITCC has great potential for applications in tandem organic solar cells.
Journal ArticleDOI
Determining the role of polymer molecular weight for high-performance all-polymer solar cells: its effect on polymer aggregation and phase separation.
Hyunbum Kang,Mohammad Afsar Uddin,Changyeon Lee,Ki-Hyun Kim,Thanh Luan Nguyen,Wonho Lee,Yuxiang Li,Cheng Wang,Han Young Woo,Bumjoon J. Kim +9 more
TL;DR: High M(n) PPDT2FBT(H) promoted a strong "face-on" geometry in the blend film, suppressed the formation of an excessively large crystalline domain, and facilitated molecularly intermixed phases with P(NDI2OD-T2), leading to a power conversion efficiency exceeding 5%, which is one of the highest values for all-PSCs reported thus far.
Journal ArticleDOI
Solvent Effects on the Two-Photon Absorption of Distyrylbenzene Chromophores
Han Young Woo,Bin Liu,Bernhard Kohler,Dmitry Korystov,and Alexander Mikhailovsky,Guillermo C. Bazan +5 more
TL;DR: A series of organic- and water-soluble distyrylbenzene-based two-photon absorption fluorophores containing dialkylamino donor groups at the termini was designed, synthesized, and characterized and a correlation between the observed solvent effect and previous theoretical predictions was failed.
