High performance of Bi2Te3-based thermoelectric generator owing to pressure in fabrication process
Applied Energy(2022)
摘要
•Additional pressure restricts interfacial resistance of TEGs.•Theoretical model governs pressure and interfacial resistance.•Low interfacial resistivity of 10μΩ·cm2 is measured in Bi2Te3-based TEG.•Conversion efficiency is increased by 44% from the commercial devices.
