Polymer-Passivated Inorganic Cesium Lead Mixed-Halide Perovskites for Stable and Efficient Solar Cells with High Open-Circuit Voltage over 1.3 V.
Qingsen Zeng,Xiaoyu Zhang,Xiaolei Feng,Siyu Lu,Zhaolai Chen,Xue Yong,Simon A. T. Redfern,Haotong Wei,Hai-Yu Wang,Huaizhong Shen,Wei Zhang,Weitao Zheng,Hao Zhang,John S. Tse,Bai Yang +14 more
TL;DR: It is demonstrated that polythiophene, deposited on the top of CsPbI2 Br, can significantly reduce electron-hole recombination within the perovskite, which is due to the electronic passivation of surface defect states, and the interfacial properties are improved by a simple annealing process.

Temperature- and Component-Dependent Degradation of Perovskite Photovoltaic Materials under Concentrated Sunlight
Ravi K. Misra,Sigalit Aharon,Baili Li,Dmitri Mogilyansky,Iris Visoly-Fisher,Lioz Etgar,Eugene A. Katz +6 more
TL;DR: The results indicate that the degradation is highly dependent on the hybrid perovskite composition and can be light- and thermally enhanced.
Journal ArticleDOI
Volume-controlled current injection in insulators
TL;DR: The physical principles underlying one-carrier space-charge-limited current injection, both steady state and transient, and steady state, twocarrier, largely neutralized current injection are discussed in this paper.

Terahertz Conductivity within Colloidal CsPbBr3 Perovskite Nanocrystals: Remarkably High Carrier Mobilities and Large Diffusion Lengths
Gurivi Reddy Yettapu,Debnath Talukdar,Sohini Sarkar,Abhishek Swarnkar,Angshuman Nag,Prasenjit Ghosh,Pankaj Mandal +6 more
TL;DR: These results confirm a negligible influence of surface defects in trapping charge carriers, which in turn results into desirable intrinsic transport properties, from the perspective of device applications, such as remarkably high carrier mobility, large diffusion length, and high luminescence quantum yield.
