“…Owing to the arising demand for precise detection of ultraviolet radiation in civil and military applications, the development of ultraviolet photodetectors with energy efficiency, a sustainable optical energy detection system, and essential and cost-effective wide bandgap material, such as TiO 2 , SnO 2 , ZnO, GaN, SiC, graphene, MoS, and quantum dots, have become vital [1][2][3][4][5][6][7][8]. In addition, the development of modern ultraviolet photodetectors is necessary, because the human body is sensitive to UV radiation that may cause different diseases, including cataracts and skin cancer [9][10][11][12]. Hence, self-powered photoelectrochemical (PEC)-type UV photodetectors (UVPDs) have emerged as a promising optoelectronic device based on photovoltaic effect, that meet the demand of energyefficiency, simple fabrication process, small size, reduced weight, cost-effective, and outstanding photodetection performance for a next generation nanodevice [10,[13][14][15].…”
