Recent development of thermoelectric materials and devices at Cardiff

Release time:April 1, 2015 /

Date:Apr.2,2015

Time: 9:30AM

Venue: IRC425 Assembly Room

Abstract:

Thermoelectric devices are solid-state energy converters that can directly convert waste heat into electric power with unique advantages of no moving parts, no noise and highly reliable. They are increasingly being seen as having the potential to make important contributions to reducing CO2 and greenhouse gas emissions and providing cleaner forms of energy. The talk will start with an introduction to thermoelectric phenomena, their potential applications, and the requirements for materials development. This will be followed by a brief review on some of the key approaches currently employed in the search for high efficiency thermoelectric materials and a discussion on the limitation of those approaches. Possible solutions and alternative approaches, which are currently being investigated at Cardiff, will be presented.

Introduction of the Speaker:

Gao Min is the Head of Thermoelectric Laboratory at School of Engineering, Cardiff University, UK. He obtained BSc on semiconductor physics from Xidian University in 1982 and PhD on thermoelectrics from Cardiff University in 1996. He was a visiting scientist in NanoEngineering Laboratory MIT, USA in 2005. His research in thermoelectric field has resulted in more than 100 publications in scientific journals and conference proceedings, 1 book and 4 book chapters, and many invited lectures to USA, UK, Czech, Thailand, and China. Currently, he is a committee member of European Thermoelectric Society and expert reviewer for EU H2020 programme. He main research interests focus on fundamental understanding of thermoelectric processes for energy harvesting applications. Current research involves developing novel thermoelectric measurement techniques, design and fabrication of high temperature thermoelectric devices, and PV/TE integrated systems.
