Thermoelectric materials are a class of materials that can convert heat into electricity, or vice versa, through the phenomenon known as the Seebeck effect. This field of research focuses on developing materials with high thermoelectric efficiency, which can be used in various applications such as waste heat recovery, power generation, and cooling systems. The goal is to find materials that can efficiently convert heat into electricity or vice versa, with minimal energy loss. Researchers are exploring new materials and strategies to improve the performance of thermoelectric materials, with the aim of creating more sustainable and efficient energy conversion technologies.
