Recent Progress on Cesium Lead Halide Perovskites for Photodetection Applications

Abstract

Recently, metal halide perovskites have attracted tremendous attention because of the unprecedented development in the research field of optoelectronic applications. Among the perovskites, all-inorganic halide perovskites (IHPs), especially the cesium lead halide type, show great potential for light-emitting devices because of their excellent optoelectronic properties, such as an ultrahigh photoluminescence quantum yield, high absorption coefficient, and large carrier mobility. Moreover, recent advancements have demonstrated that the extraordinary optical and electrical properties combined with a high chemical stability and facile synthesis make IHPs promising candidates for next-generation high-performance photodetectors (PDs) beyond lightemitting technologies. In this Review, the syntheses of IHPs with different forms, as well as their fundamental optical and electronic properties, are first summarized and compared. Thereafter, we focus on the recent progress of IHP-based PDs working with different wavelengths, covering the infrared, visible, ultraviolet, and gamma regions. Then, the challenges and opportunities facing the field of PDs based on IHPs are discussed. Finally, a brief outlook is given for the future development of IHP-based PDs.

Anisotropic shape of CsPbBr3 colloidal nanocrystals: from 1D to 2D confinement effects

“…Let us note that their excellent optoelectronic properties make 2D CsPbBr3 systems very serious candidates for the next-generation high-performance photodetectors. 62 Moreover, the access to facile deposition methods paves the way to important developments in advanced nanophotonics or quantum optics using such nanocrystals as gain media, either in ensemble, as for instance in microcavity polaritonics 63 , or as individual emitters coupled to nanoguides. 64 The control of self-assembling or postorientation 65 might also provide an access to renewed or improved emission properties, like superfluorecence 66 but should also facilitate the penetration of new fields such as excitonic spin physics that requires well controlled magnetooptical configurations (free of orientation disorder) and that starts to be investigated in perovskite bulk-like materials.…”

Antisolvent‐Induced Fastly Grown All‐Inorganic Perovskite CsPbCl3 Microcrystal Films for High‐Sensitive UV Photodetectors

“…[ 3 ] Recently, compared with the widely studied and extensively used organic–inorganic hybrid halide perovskites in optoelectronic and photovoltaic devices, all‐inorganic halide perovskite CsPbCl 3 not only has excellent photoelectric properties, but also naturally possesses the better chemical stability and bandgap tunability due to the replacement of organic methyl ammonium with inorganic Cs cations.

“…In addition, it is worth noticing that all-inorganic single junction devices offer interesting potential applications in high impact optoelectronics. Examples include photodetectors for gamma and X-rays detection, [107][108][109][110][111] scintillators, [112][113][114][115] photocatalysts, [116][117][118][119] and light emitting devices, [120][121][122][123] offering a plethora of new attractive solutions.…”
