Dr. Chen was selected as a Hundred-Talent Program Researcher of Chinese Academy of Sciences in 2012. He has successfully developed several technologies and products. For example, a heat treatment technology can reduce age-softening effect in Al-Mg alloy, which can save lots of aluminum alloy for industry; NiMnGa magnetic shape memory alloys are on-trial tests on missile flight control and ocean wave energy harvesting in navy; During his work in 6N Silicon Inc of Canada, he invented a technology, which enabled mass production of solar grade silicon by Al-Si alloy method for the first time and hence received several awards worldwide. During the research of silicon purification by Al-Si alloy method, he has proposed a concept of apparent segregation coefficient and method to calculate it. By studying the coupling effects between temperature field, melt convection field, electromagnetic field and interaction between impurity elements, he has greatly improved the efficiency of purification of the key impurity elements B and P by the Al-Si alloy method. The purification efficiency of both B and P broke records to beyond the thermodynamic limits, which lays a solid foundation for commercializing this technology. In addition, he has published more than 60 technical papers, applied more than 10 patents. His current research projects include Hundred-Talent Program of Chinese Academy of Sciences, National Natural Science Fund etc. 

Current research activities mainly focus on the following areas:
1. Solar cell materials 
2. Li-ion battery materials
3. Mineral materials purification and processing
