Nicholas De Marco,Huanping Zhou,Qi Chen,Pengyu Sun,Zonghao Liu,Lei Meng,En-Ping Yao,Yongsheng Liu,Andy Schiffer,Yang Yang +9 more
TL;DR: A simple method for suppressing nonradiative carrier loss in hybrid perovskites to further improve performances toward highly efficient solar cells is presented.
Journal ArticleDOI
High-performance perovskite/Cu(In,Ga)Se2 monolithic tandem solar cells
Qifeng Han,Yao-Tsung Hsieh,Lei Meng,Jyh-Lih Wu,Pengyu Sun,En-Ping Yao,Sheng-Yung Chang,Sang-Hoon Bae,Takuya Kato,Veronica Bermudez,Yang Yang +10 more
TL;DR: Control of the roughness of the CIGS surface and the use of a heavily doped organic hole transport layer were crucial to achieve a 22.4% power conversion efficiency in a two-terminal tandem cell with hybrid perovskite/CIGS combination.
Journal ArticleDOI
High-Brightness Blue and White LEDs based on Inorganic Perovskite Nanocrystals and their Composites
TL;DR: Blue-emission (≈470 nm) Cs-based perovskite NCs are derived by directly mixing synthesized bromide and chloride nanocrystals with a weight ratio of 2:1.
Journal ArticleDOI
Carbon Quantum Dots/TiOx Electron Transport Layer Boosts Efficiency of Planar Heterojunction Perovskite Solar Cells to 19%
Hao Li,Weina Shi,Wenchao Huang,En-Ping Yao,En-Ping Yao,Junbo Han,Zhifan Chen,Shuangshuang Liu,Yan Shen,Mingkui Wang,Yang Yang +10 more
TL;DR: A solution-processed carbon quantum dots (CQDs)/TiO2 composite that has negligible absorption in the visible spectral range, a very attractive feature for perovskite solar cells is reported.
Journal ArticleDOI
Pure Formamidinium-Based Perovskite Light-Emitting Diodes with High Efficiency and Low Driving Voltage
Lei Meng,En-Ping Yao,En-Ping Yao,Ziruo Hong,Huajun Chen,Pengyu Sun,Zhanlue Yang,Gang Li,Gang Li,Yang Yang +9 more
TL;DR: A formamidinium(FA)-based perovskite showns superior optoelectronic properties including better stability than methylammonium-based counterparts, and Interestingly, the LED clearly shows a sub-bandgap emission at 1.7 V (bandgap 2.3 eV).
