Resume:

Prof./Dr. Shengqiang Bai is the deputy head of thermoelectric (TE) materials and device research group, member of Chinese Thermoelectric Society C-MRS, and the vice chair of Advanced Materials for Transportation (AMT) in IEA Technology Collaboration Program (TCP). He has engaged in the studies of full-chain techniques of TE devices with high efficiency and high reliability. The “chemical reaction and diffusion” model was introduced to reveal the structure evolution of electrode interface and the degradation mechanism of TE devices. Based on these understanding, interface optimization method and advanced bonding technologies were developed to ensure both high reliability and minimum energy loss in TE devices. The proposed full-parameter optimization model successfully boosting the output performance of various TE devices and fully released the potential efficiency of segmented devices. The “Device-to-Material” strategy realized the “double-high” (high efficiency and high power density) devices. These novel TE devices were applied in the demonstrated power generation in the fields of such as industrial waste heat recovering, solar thermal energy utilization, and space power supply. He received the Second prize of National Technological Invention Award (R3).
