报告题目：Design and control of interface and structure of electrodes for energy conversion and storage
报告内容摘要：In this presentation, he will share his recent research results and better understanding of some old results on both solar cells and battery electrodes. For solar cell research, he will demonstrate and discuss how the micro- and nanostructures and surface chemistry of photoanode would affect the power conversion efficiency; similarly, the significant impacts of the insertion of extra quantum dot layers and plasmonic nanocrystals as well as the doping or alloying in quantum dots on photon capturing, charge transfer and interface recombination will be elaborated. In the second part of the seminar, the focus will be devoted to the better understanding how the controlling factors in electrode materials affect the lithium-ion storage capacity and electrochemical potential. Particularly he will have a little in-depth discussion on the reversible 1st order phase transition and impacts of crystal field on the lithium ion storage through intercalation reactions.
