Composite Strategy to Enhance the Thermoelectric Performance of Chalcogenide-based Materials

Thermoelectric (TE) materials, which can directly convert heat to electrical energy or vice-versa, offer the simplest and most environmentally friendly solution for versatile power generation and solid-state refrigeration. However, the critical limitation for the widespread applications of TE technology is the relatively low conversion efficiency of materials. Finding and developing high-efficiency TE materials is the main task involved in developing competitive TE technology for large-scale commercial applications.
