Improved Performance and Stability of All-Inorganic Perovskite Light-Emitting Diodes by Antisolvent Vapor Treatment
Chen Wu,Yatao Zou,Tian Wu,Muyang Ban,Vincenzo Pecunia,Yujie Han,Qipeng Liu,Tao Song,Steffen Duhm,Baoquan Sun +9 more
TL;DR: In this paper, a unique method is developed to obtain high quality CsPbBr3 emitting layers with low defects by controlling their grain sizes, leading to microcrystals with a size of ≈5 µm along the inplane direction with active emitting composite of 90%.
Journal ArticleDOI
Boosting Perovskite Light-Emitting Diode Performance via Tailoring Interfacial Contact.
Yatao Zou,Muyang Ban,Yingguo Yang,Sai Bai,Chen Wu,Yujie Han,Tian Wu,Yeshu Tan,Qi Huang,Xingyu Gao,Tao Song,Qiao Zhang,Baoquan Sun +12 more
TL;DR: This work develops a strategy to modify the interface between the hole transport layer and the perovskite emissive layer with an amphiphilic conjugated polymer of poly[(9,9-bis(3'-( N, N-dimethylamino)propyl)-2,7-fluorene)- alt-2,8-dioctylfluorene)] (PFN), and shows evidences that PFN improves the quality of theperov
Journal ArticleDOI
Enormously improved CH3NH3PbI3 film surface for environmentally stable planar perovskite solar cells with PCE exceeding 19.9
Yingguo Yang,Shanglei Feng,Meng Li,Fangchao Li,Cong-Cong Zhang,Yujie Han,Yujie Han,Li Li,Jianyu Yuan,Liang Cao,Zhao-Kui Wang,Baoquan Sun,Xingyu Gao +12 more
TL;DR: In this paper, a novel anti-solvent washing treatment simply using Hydrogen Iodide (HI) additive in chlorobenzene (CB) can enormously improve CH3NH3PbI3 films surface with high crystallization phase purity and chemical homogeneity, leading to excellent structural stability under humidity, heat and even tensile force.
Journal ArticleDOI
Naphthalene Diimide-Based n-Type Polymers: Efficient Rear Interlayers for High-Performance Silicon–Organic Heterojunction Solar Cells
Yujie Han,Yuqiang Liu,Jianyu Yuan,Huilong Dong,Youyong Li,Wanli Ma,Shuit-Tong Lee,Baoquan Sun +7 more
TL;DR: The success of NDI-based polymers indicates that planar conjugated polymer with a preferred orientation could be useful in developing high-performance solution-processed Si-organic heterojunction photovoltaic devices.
Journal ArticleDOI
Investigation of MoOx/n-Si strong inversion layer interfaces via dopant-free heterocontact
Teng Sun,Rongbin Wang,Rongbin Wang,Ruiyuan Liu,Chen Wu,Yanan Zhong,Yuqiang Liu,Yusheng Wang,Yujie Han,Zhouhui Xia,Yatao Zou,Tao Song,Norbert Koch,Norbert Koch,Steffen Duhm,Baoquan Sun +15 more
TL;DR: In this article, a dopant-free heterocontact is built within n-Si with a high built-in potential (Vbi) of ∼080'V which benefits for acquiring a high open circuit voltage (Voc).
