报告摘要：

　　Transparent conducting materials (TCMs) are widely used in optoelectronic devices, including solar cells, touch screens and smart windows. TCMs combine two seemingly contradicting properties, i.e., high electrical conductivity and high visible light optical transmission and the origin of their unusual physical properties remains inadequately understood. In this presentation, I will provide a brief overview of our current understanding on the TCMs and discuss our recent advancements in band structure engineering and doping control within TCMs. Specifically, I will discuss (i) the fundamental band structures and defect properties of conventional TCMs; (ii) strategies aimed at concurrently enhancing optical transparency and conductivity in n-type TCMs; and (iii) explorations and challenges associated with achieving p-type TCMs or even bipolarly dopable TCMs.
