The research team closely follows the international research hotspots and national major science and technology strategies in the field of materials, mainly engaged in the research of new energy and environmental materials, new solar cell materials, semiconductor ULSI integrated circuit wiring materials. The research focuses on solar silicon substrate materials and devices in photovoltaic industry, nanoporous silicon preparation and application in heavy metal environmental treatment, silicon based wiring and interconnection thin film materials for ULSI in information industry. The research work of this research team has been funded and supported by the National Natural Science Foundation of China, the Fund for Returned Scholars of the Ministry of Education, the Major Science and Technology Projects of Yunnan Science and Technology Department, and the Open Fund of the State Key Laboratory of the State Key Laboratory of Clean Utilization of Complex Non-ferrous Metal Resources in Yunnan Province. The research areas involve the following aspects.
（1）Research on adsorption of heavy metal ions in industrial wastewater by porous silicon material. The related research work in this part was supported by two National Natural Science Funds of China and the Open Fund of the State Key Laboratory of the State Key Laboratory of Clean Utilization of Complex Non-ferrous Metal Resources in Yunnan Province. The research group has published many SCI papers in JHM, Coatings, MP, CJSC and other journals, and 6 master graduates have been trained.
（2）Research on new silicon-based solar cell materials and devices with nano-metal assisted etching, and prepare silicon wafers with different structures through effective regulation to achieve efficient reflection reduction effect on the surface of solar silicon wafers and improve the luminescence efficiency. This part of the related research work has been supported by the key project of Yunnan Provincial Science and Technology Department and the National Fund. The research group has published many SCI and EI papers on IJMR, ESPR, PT and other journals，and 6 master graduates have been trained.
