Thermoelectric refrigeration is a solid-state refrigeration technology that uses electric energy to achieve refrigeration via the Peltier effect. Compared with vapor compression refrigeration

thermoelectric refrigeration offers the advantages of scalability

vibration-free

high reliability

and high temperature-control accuracy. Based on the development history and basic principles of thermoelectric refrigeration

this study focuses on the research progress of thermoelectric materials

refrigerator structures

functional layer interfaces

and heat sinks. Subsequently

applications of thermoelectric refrigeration are introduced based on their advantages. Finally

investigations regarding thermoelectric refrigeration are summarized and discussed.
