“…However, a large number of defects in polycrystalline films limit the device performances. Alternatively, perovskite single crystals are expected to achieve impressive photosensing performances due to their absence of grain boundaries, low trap densities, and large carrier mobilities . Apart from polycrystalline film and single crystal, low‐dimensional perovskite nanostructures including 1D nanowire and 2D nanosheet have been successfully synthesized and received increasing research attention, primarily for their fascinating optical and electronic properties resulting from the quantum‐size effects .…”

Hybrid organic-inorganic perovskite materials garner enormous attention for a wide range of optoelectronic devices. Due to their attractive optical and electrical properties including high optical absorption coefficient, high carrier mobility, and long carrier diffusion length, perovskites have opened up a great opportunity for high performance photodetectors. This review aims to give a comprehensive summary of the significant results on perovskite-based photodetectors, focusing on the relationship among the perovskite structures, device configurations, and photodetecting performances. An introduction of recent progress in various perovskite structure-based photodetectors is provided. The emphasis is placed on the correlation between the perovskite structure and the device performance. Next, recent developments of bandgap-tunable perovskite and hybrid photodetectors built from perovskite heterostructures are highlighted. Then, effective approaches to enhance the stability of perovskite photodetector are presented, followed by the introduction of flexible and self-powered perovskite photodetectors. Finally, a summary of the previous results is given, and the major challenges that need to be addressed in the future are outlined. A comprehensive summary of the research status on perovskite photodetectors is hoped to push forward the development of this field.

“…Surthi et al have reported an integrated structure of a semiconducting La–Ca–Mn–oxide and SbSI, which was used as a ferroelectric memory element. Chen et al have reported an individual SbSI photodetector using SbSI microrods. Theoretical calculations revealed a high charge mobility for SbSI, related to the low effective masses of the charge carriers; hence, SbSI demonstrates promise for photovoltaic applications .…”

Although antimony sulfoiodide (SbSI) exhibits very interesting properties including high photoconductivity, ferroelectricity, and piezoelectricity, it is not applied to solar cells. Meanwhile, SbSI is predominantly prepared as a powder using a high‐temperature, high‐pressure system. Herein, the fabrication of solar cells utilizing SbSI as light harvesters is reported for the first time to the best of knowledge. SbSI is prepared by solution processing, followed by annealing under mild temperature conditions by a reaction between antimony trisulfide, which is deposited by chemical bath deposition on a mesoporous TiO2 electrode and antimony triiodide, under air at a low temperature (90 °C) without any external pressure. The solar cells fabricated using SbSI exhibit a power conversion efficiency of 3.05% under standard illumination conditions of 100 mW cm−2.

“…The SbSI is easy to grow into one-dimensional rods or urchin-like structures, [22][23][24][25]32 even from a continuous thin film. 22 Therefore, to apply these discontinuous SbSI films into planar optoelectronic devices, an insulating polymer such as poly(methyl methacrylate) 22,27 should be integrated into such films to minimize leakage currents caused by the presence of inevitable voids in the SbSI layer.…”

We report a simple solution processing method for fabricating low-temperature SbSI solar cells. The method consists of two steps: the formation of amorphous Sb2S3 and its transformation to SbSI. A pure SbSI phase with a high crystallinity was obtained at a low temperature of 200 °C. In addition, the SbSI morphology was controlled by tuning the input ratio of SbCl3:thiourea and a dense film was obtained at a ratio of 1:1.3. A planar SbSI solar cell thus-fabricated exhibits a short-circuit current density of 5.45 mA cm−2, an open-circuit voltage of 0.548 V, and a fill factor of 0.31, corresponding to a power conversion efficiency of 0.93% under a 100 mW cm−2 illumination condition.
