As a scanning probe technology, scanning electrochemical microscopy (SECM) plays an important role in the research of metal corrosion, material characterization, biomedicine and new energy technologies. This paper briefly introduces the basic working principle of SECM and two commonly used working modes: feedback mode and collection / generation mode. The application progress of SECM in solar photovoltaic and solar photovoltaic hydrogen production are reviewed. At the same time, Working group of the group, in particular, the recent screening of the use of SECM doped metal ion doped WO3 photoanode work, SECM in the screening of semiconductor electrode materials, the application of the characteristics of an example shows the introduction, concludes with a brief summary of the SECM photovoltaic energy Research area of development and direction.
