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 this study, we reported an all-inorganic CsPbBr3split-ring structured photodetector (SRP) array for non-contact human–machine interaction (Fig.1). We developed a dual-function laser etching scheme that can simultaneously complete the patterning of lyophilic layer and electrodes, which greatly r...
All-inorganic perovskite nanocrystal materials: new generation of scintillators for high quality X-ray Imaging Scintillating materials, which can convert high energy X-ray radiation into visible luminescence [1], are crucial parts of Xray ... K Wang,H Zhang,Z Gu - 《Science Bulletin》 被引量:...
All-inorganic perovskite solar cells (PSCs) are regarded as a promising solution to improve the environmental tolerance of emerging photovoltaics; however, the narrow light response (<550 nm) of cesium lead bromide (CsPbBr3) perovskites markedly lowers their power conversion efficiency (PCE). We pr...
A luminescent all-inorganic manganese-bismuth heterometallic Cs4MnBi2Cl12 perovskite single crystal has been synthesized with a [BiCl6]3−-[MnCl6]4−-[BiCl6]3− triple-layered two-dimensional structure. Benefit from the effective energy transfer from [BiCl6]3− octahedron donor to lumines...
Abstract All-inorganic zero-dimensional (0D) tetrahedrite (Cu12Sb4S13, CAS) quantum dots (QDs) have attracted extensive attention due to their excellent optical properties, bandgap tunability, and carrier mobility. In this paper, various sized CAS QDs (5.1, 6.7, and 7.9 nm) are applied as...
All-inorganic halide perovskite nanocrystals (NCs) have become the most promising next generation luminescent materials due to their excellent properties. However, there are many nonradiative recombination defects in colloidal perovskite NCs, which reduce their luminescent efficiency and stability. In this ...

Here, we perform TR-XRD on cesium lead bromide NCs, which are prototypical all-inorganic lead trihalide perovskite NCs39,40,41,42. The studies reveal multiple regimes of material response ranging from...
There have been incredible developments in organic-inorganic hybrid lead halide perovskite solar cells (PSCs) recently. In fact, their power conversion efficiency (PCE) has skyrocketed from 3.8 to 22.7% in just a few years1,2,3,4,5. Unfortunately, the hybrid perovskite suffers from unavoidable...
