Hairen Tan,Ankit Jain,Oleksandr Voznyy,Xinzheng Lan,F. Pelayo García de Arquer,James Z. Fan,Rafael Quintero-Bermudez,Mingjian Yuan,Bo Zhang,Yicheng Zhao,Fengjia Fan,Peicheng Li,Li Na Quan,Yongbiao Zhao,Zheng-Hong Lu,Zhenyu Yang,Sjoerd Hoogland,Edward H. Sargent +17 more
TL;DR: A contact-passivation strategy using chlorine-capped TiO2 colloidal nanocrystal film that mitigates interfacial recombination and improves interface binding in low-temperature planar solar cells is reported.
Journal ArticleDOI
A polymer scaffold for self-healing perovskite solar cells.
TL;DR: Not only the film can self-heal in this case, but the corresponding devices can present power conversion efficiency recovery after the water vapour is removed, demonstrating the value of cheap, long chain and hygroscopic polymer scaffold in perovskite solar cells towards commercialization.
Journal ArticleDOI
Suppression of atomic vacancies via incorporation of isovalent small ions to increase the stability of halide perovskite solar cells in ambient air
Makhsud I. Saidaminov,Junghwan Kim,Ankit Jain,Rafael Quintero-Bermudez,Hairen Tan,Guankui Long,Furui Tan,Andrew Johnston,Yicheng Zhao,Oleksandr Voznyy,Edward H. Sargent +10 more
TL;DR: In this article, the effect of local lattice strain on vacancy formation was investigated in single-cation/halide perovskites and the authors showed that judiciously selected dopants can maximize the formation energy of defects responsible for degradation.
Journal ArticleDOI
Hysteresis Analysis Based on the Ferroelectric Effect in Hybrid Perovskite Solar Cells
TL;DR: This work provides a meaningful perspective that the ferroelectric effect (if it really exists) should be paid special attention in the optimization of perovskite solar cells and proves that prolonged stepwise measurement is an effective way to evaluate the real efficiency of perovsky solar cells.
Journal ArticleDOI
Quantification of light-enhanced ionic transport in lead iodide perovskite thin films and its solar cell applications
TL;DR: A novel light-assisted method of catalyzing ionic interdiffusion between CH3NH3I and PbI2 stacking layers in sequential deposition perovskite synthesis is designed, which enables fine control of the reaction depth in perovSKite synthesis and, in turn, supports light-enhanced ionic transport.
