Description
technical field [0001] The invention relates to the technical field of solar-blind photodetection, in particular to a photoelectrochemical self-powered solar-blind deep ultraviolet photodetector and a preparation method thereof. Background technique [0002] Solar-blind deep-ultraviolet photodetectors (PDs) can detect deep-ultraviolet light signals under sunlight environment conditions because they are not interfered by sunlight, so they have very important applications in the fields of military, national defense and scientific research. Most of the existing deep ultraviolet photodetectors are microchannel plate (MCP), photomultiplier tube (PMT), silicon-based charge-coupled device (CCD) and semiconductor photodiode, however, such as high voltage bias requirements, poor spectral selectivity, filtering Several disadvantages such as photodetectors limit the wide application of these photodetectors. In this case, the use of ultra-wideband (UWB) semiconductors, which are natura...
