Caesium lead triiodide perovskite (CsPbI3)Organometal lead halides perovskites are promising solar cells material due to their outstanding properties such as tuneable bandgap, impressive tolerance to defects, long exciton diffusion length, high carrier mobility and absorption coefficient. Up to now, the ...
Consequently, the CsPbI 2 Br-based all-inorganic perovskite solar cells (PSCs) exhibit power conversion efficiencies (PCE) of up to a record value of 10.56%. This low temperature crystallization of all-inorganic CsPbI 2 Br perovskite is a promising approach for scalable, convenient, and ...
Making organic–inorganic metal halide-based multijunction perovskite solar cells either by solution processes or physical techniques is not straightforward. Here we propose and developed dimethylammonium iodide-assisted β−CsPbI3 and guanidinium iodi
All-inorganic perovskite solar cells (PVSCs) have drawn increasing attention because of their outstanding thermal stability. However, their performance is still inferior than the typical organic-inorganic counterparts, especially for the devices with p-i-n configuration. Herein, we successfully employ a...
In all perovskite solar cells, the dominant centres for nonradiative recombination are the iodine atoms. According to the calculations by Van de Walle and colleagues, their presence creates a loss mechanism that is similar in both types of device. ...

Perovskite solar cells based on inorganic perovskites and carbon-electrodes offer high stability, facile fabrication and low-costs. To improve the photovoltaic performance of CsPbI3−xBrx C-IPSCs, innovative strategies have been developed, such as modifying deposition methods, elemental doping, interfac...
Here, we passivated the interfacial defects of ZnO/CsPbBr3 by inserting a NaSCN layer between the ZnO electron transport layer and the CsPbBr3 layer to imp
All-inorganic perovskites prepared by substituting the organic cations (for example, methylammonium and formamidinium) with inorganic cations (for example, Cs+) are effective concepts to enhance the long-term photostability and thermal stability of perovskite solar cells (PSCs)1,2. Hence, inorganic ...
