Uniform Permutation of Quasi-2D Perovskites by Vacuum Poling for Efficient, High-Fill-Factor Solar Cells
Jia Zhang,Jiajun Qin,Miaosheng Wang,Yujie Bai,Han Zou,Jong K. Keum,Runming Tao,Hengxing Xu,Haomiao Yu,Stefan Haacke,Bin Hu +10 more
TL;DR: In this paper, a different strategy of uniformly arranging different n-value nanoplates (PEA2MAn-1PbnI3n+1) by introducing vacuum poling treatment to enforce nucleation during crystallization is reported.
Journal ArticleDOI
Lead-Free Cs2BiAgBr6 Double Perovskite-Based Humidity Sensor with Superfast Recovery Time
Zhenhua Weng,Jiajun Qin,Akrajas Ali Umar,Akrajas Ali Umar,Jiao Wang,Xin Zhang,Haoliang Wang,Haoliang Wang,Xiaolei Cui,Xiaoguo Li,Xiaoguo Li,Lirong Zheng,Lirong Zheng,Yiqiang Zhan +13 more
TL;DR: In this paper, the moisture sensitivity of lead halide perovskite has been investigated in photoelectric applications owing to their unique properties, and it has been shown that the moisture sensitive properties of LH-perovskites can be improved.
Journal ArticleDOI
Degradation and self-repairing in perovskite light-emitting diodes
Pengpeng Teng,Sebastian Reichert,Weidong Xu,Shih-Chi Yang,Fan Fu,Yatao Zou,Chunyang Yin,Chunxiong Bao,Max J. Karlsson,Xianjie Liu,Jiajun Qin,Tao Yu,Wolfgang Tress,Ying Yang,Baoquan Sun,Carsten Deibel,Feng Gao +16 more
TL;DR: In this paper, the accumulated halides within the hole transport layer undergo back-diffusion toward the surface of the perovskite layer during resting, repairing the vacancies and thus resulting in electroluminescence recovery.
Journal ArticleDOI
