Photoelectrochemical sensing is an attractive tool for rapid and accurate monitor of chemical and biochemical mole-cules. Compared with conventional analysis techniques, photoelectrochemical sensing exhibits unique technique superiority and has become a hot topic in material chemis-try and analytical chemistry. This review provides an over-view of the important advances in the construction and application of photoelectrochemical sensing in recent year. In the first segment, we briefly introduce the general princi-ple and technical characteristic of photoelectrochemical sensing. In the subsequent sections, we primarily devote to elaborating the typical strategies of design and engineering photoactive materials for improve the light excitation as well as charge separation/transfer to modulate the perfor-mance of photoelectrochemical sensing system. Addition-ally, the current research status of photoelectrochemical sensing with a particular emphasis on the innovative sens-ing devices and detection modes for achieving specific sensing functions is describes in detail with the illustrative examples. Finally, the critical challenges on the journey to achieve real-life applications of photoelectrochemical sens-ing and the viable solutions for solving these problems as well as the future research perspectives are discussed.
