moderate UV light is beneficial for human health, however, excessive UV radiation can cause various human diseases as well as strong destruction to the output of crops and the lifespan of buildings. [1b,3a,4] Therefore, an efficient detection of UV radiation is of significant importance in widespread applications, for example, chemical, environmental, and biological analysis or warning, astronomical investigation, and optical communication. [1c,5] For forewarning UV radiation with high-efficiency, a wide variety of UV PDs such as photomultiplier and silicon diode, have been extensively investigated and applied in the past decades. Nevertheless, there are intrinsic imperfections for the present commercial PDs, such as fragile, large volume, and excessive cost, which are obstacles when meeting the growing requirement of miniaturized and reliable UV detection devices for portable or shipped applications. In recent years, the development of semiconductor-based PDs that work according to the photoelectric effect has received great research interest. [1b,3a,6] In this scenario, a delicate selection of suitable materials with efficient morphological, microstructural, and photoelectrical characteristics plays a key role in the construction of PDs with high-performance. Generally, the PDs work following several different physical mechanisms, that is, surface plasma-wave-assisted effect, photoconductive effect, photothermoelectric effect, and photovoltaic effect, which have been systematically demonstrated in the previous report. [7] More recently, a new generation of wide-bandgap semiconductors including the classification of nitrides (GaN, AlN, BN, etc.), carbides (SiC, diamond, etc.), sulfides (ZnS, etc.), oxides (ZnO, Ga 2 O 3 , TiO 2 , etc.), halide perovskites (e.g., CH 3 NH 3 PbCl 3 ), [8] and their combinations, is emerged as the most attractive material candidates for constructing high-performance UV PDs, owing to their unique advantages, for instance low permittivity, high breakdown electric-fields, good thermal conductivity, high electron saturation rates, excellent radiation resistance, and their appropriate spectral range for UV response. [1d] In addition, the photoelectric conversion processes of the semiconductorbased PDs can be generally described by the behaviors of charge carriers, such as their generation, separation, transportation, and extraction. [9] Therefore, any factor that influences the photon-generated carrier behaviors should be the key parameter for further tuning their photodetecting performances. It As a wide-bandgap semiconductor material, titanium dioxide (TiO 2 ), which possesses three crystal polymorphs (i.e., rutile, anatase, and brookite), has gained tremendous attention as a cutting-edge material for application in the environment and energy fields. Based on the strong attractiveness from its advantages such as high stability, excellent photoelectric properties, and lowcost fabrication, the construction of high-performance photodetectors (PDs) based on TiO 2 nanostructures is ...

Ultraviolet-C (UVC) radiation is employed in various applications, including irreplaceable applications in military and civil fields, such as missile guidance, flame detection, partial discharge detection, disinfection, and wireless communication. Although most modern electronics are based on Si, UVC detection technology remains a unique exception because the short wavelength of UV radiation makes efficient detection with Si difficult. In this review, recent challenges in obtaining ideal UVC photodetectors with various materials and various forms are introduced. An ideal photodetector must satisfy the following requirements: high sensitivity, fast response speed, high on/off photocurrent ratio, good regional selectivity, outstanding reproducibility, and superior thermal and photo stabilities. UVC detection is still in its infancy compared to the detection of UVA as well as other photon spectra, and recent research has focused on different key components, including the configuration, material, and substrate, to acquire battery-free, super-sensitive, ultra-stable, ultra-small, and portable UVC photodetectors. We introduce and discuss the strategies for fabricating self-powered UVC photodetectors on flexible substrates in terms of the structure, material, and direction of incoming radiation. We also explain the physical mechanisms of self-powered devices with various architectures. Finally, we present a brief outlook that discusses the challenges and future strategies for deep-UVC photodetectors.

Although it accounts for less than 10% of the total sunlight, UV radiation has a severe influence on humanity. The International Commission on Illumination (CIE) divides the spectrum of solar electromagnetic radiation into three bands, as shown in Figure 1: UVA (315-400 nm), UVB (280-315 nm), and UVC (100-280 nm). [1] Among them, UVA and UVB are mainly derived from the natural environment. They account for 90%-95% and 5%-10% of solar radiation, respectively, and are of the part of sunlight that leads to sunburn, skin cancers, and cataracts. [2][3][4][5] Until now, many photodetectors, which detect UV radiation with wavelengths longer than 280 nm, have been integrated into weather forecast programs to prevent UVA andThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

Metal oxides have attracted more and more attention as common candidates for photodetectors. However, most metal oxide detectors are limited by the shortcomings such as wide band gap, high manufacturing cost, and slow response speed. In this work, a UV‐visible Bi2O3/In2O3 heterojunction photodetector was successfully achieved by a two‐step spin coating method. Based on X‐ray diffraction (XRD) and scanning electron microscopy (SEM) measurements, the crystal form and morphology of the Bi2O3/In2O3 heterojunction were determined. The UV‐visible absorption spectroscopy and UV photoelectron spectroscopy (UPS) tests indicate that the Bi2O3/In2O3 formed a type II heterojunction and the successful combination of the two enhanced the light detection capability of the photodetector. Additionally, the Bi2O3/In2O3 heterojunction photodetector possesses a self‐powered characteristic with a responsivity, detectivity, and response time of 0.66 mA/W, 5.78×1010 Jones, and 1.90 s, respectively. The above results demonstrate that the multilayer Bi2O3/In2O3 heterojunction is a promising UV‐visible broadband photodetector.This article is protected by copyright. All rights reserved.
