Abstract

With the continuous advancement of science and technology, SnSe thin films are widely used in various fields such as solar cells, energy harvesting, and flexible devices. The importance of SnSe thin films continues to be highlighted, from solar cells to flexible devices. With the continuous improvement of performance requirements for SnSe thin films in different fields, research on the properties of SnSe thin films has gradually become a hot topic. As an environmentally friendly and green material, SnSe thin films are more in line with modern semiconductor technology compared to crystalline materials, and they have unique advantages in the construction and application of thermoelectric micro/nano devices. This article first analyzes the characteristics of SnSe materials and then compares and analyzes PVD technologies and CVD technologies on doped SnSe thin films. In particular, it summarizes the research progress of CVD technologies on doped SnSe thin films, such as vacuum evaporation, magnetron sputtering, and pulse laser deposition, and it summarizes the research progress of PVD technologies on doped SnSe thin films, such as dual-temperature-zone CVD, the solution process method, and electrochemical deposition technology. It analyzes the performance of doped SnSe thin films prepared by different techniques. Finally, the preparation technology for the optimal thermoelectric properties of doped SnSe thin films and the approaches for potential research direction of future researchers were discussed, in the context of providing better performance SnSe thin films for the fields of solar cells, energy harvesting, and flexible devices.
