Research on New Energy Recovery Technology based on Thermoelectric Effect

Thermoelectric energy recovery technology converts industrial waste heat into electricity through Seebeck effect, but it faces the dual bottlenecks of material performance (low ZT value) and system efficiency (large interface loss). This study proposes a material-device-system three-level collaborative optimization strategy: at the material level, defect engineering and band modulation are used to enhance carrier mobility and suppress phonon transport; at the device level, gradient bonding interface and flexible structure design are used to enhance mechanical stability and electrical output performance; at the system level, intelligent collaborative control and multi-scene integration scheme are used to achieve thermal-electrical dynamic matching. The research results provide efficient solutions for industrial waste heat recovery, wearable equipment energy supply and other scenarios, and promote the engineering application of thermoelectric technology.
