Journal ArticleDOI
Lewis acid/base approach for efficacious defect passivation in perovskite solar cells
Shurong Wang,Aili Wang,Xiaoyu Deng,Lisha Xie,Andong Xiao,Chengbo Li,Yong Xiang,Tingshuai Li,Liming Ding,Feng Hao +9 more
TL;DR: In this paper, a feasible Lewis acid/base passivation strategy and its effects on energy level alignment, recombination kinetics, hysteresis behavior and operational stability for efficient PSCs are comprehensively reviewed.
Journal ArticleDOI
Emerging alkali metal ion (Li+, Na+, K+ and Rb+) doped perovskite films for efficient solar cells: recent advances and prospects
TL;DR: In this paper, a comprehensive review of the incorporation of alkali metal ions (Li+, Na+, K+ and Rb+) in emerging perovskite solar cells for a longer carrier lifetime, lower interfacial defect density, faster charge transfer, no hysteresis, higher stability and higher power conversion efficiency is presented.
Journal ArticleDOI
Understanding the Formation of Vertical Orientation in Two-dimensional Metal Halide Perovskite Thin Films
Alexander Z. Chen,Michelle Shiu,Xiaoyu Deng,Mustafa Mahmoud,Depei Zhang,Benjamin Foley,Seunghun Lee,Gaurav Giri,Joshua J. Choi +8 more
TL;DR: In this article, a general crystallization mechanism for 2D perovskites was proposed, where solvent evaporation and crystal growth compete to influence the level of supersaturation and a low supersaturation is necessary to crystallize vertically oriented thin films starting from nucleation at the liquid-air interface.
Journal ArticleDOI
Ionic liquids engineering for high-efficiency and stable perovskite solar cells
Xiaoyu Deng,Lisha Xie,Shurong Wang,Chengbo Li,Aili Wang,Yuan Yuan,Zhiyuan Cao,Tingshuai Li,Liming Ding,Feng Hao +9 more
TL;DR: In this paper, the main beneficial effects of ionic liquids including crystallization process modulation, energy level alignment, independent charge extraction layer or dopant, enhancing the moisture and thermal stability are summarized.
Journal ArticleDOI
Ionic liquid reducing energy loss and stabilizing CsPbI2Br solar cells
TL;DR: In this article, an ionic liquid of 1-butyl-3-methylimidazolium tetrafluoroborate (BMIMBF4) is proposed to stabilize the CsPbI2Br phase and reduce the surface defect density.
