Weifeng Zhang: the founder of Henan Provincial Key Laboratories 

Weifeng Zhang is a professor and doctoral supervisor at Provincial Key Laboratory of Photovoltaic Materials, Henan University. Besides teaching jobs, he is also the director of the Provincial Key Laboratory of Photovoltaic Materials, the editor of American journals JPC and JACS, and the Journal of Henan University (Natural Science Edition).

Professor Zhang obtained his Bachelor's degree from Department of Physics, Henan University in 1987 and was admitted to 3-year joint Master's program specializing in solid-state physics of Henan University and Jilin University in the same year. During his Master's study, he worked in the Solid Surface Laboratory of Henan University, engaging in the preparation of Langmuir-Blodgett ordered molecular films and researching optical and electrical properties. His research orientation - the optical properties of perovskite oxide nanomaterials and thin-film materials - successfully persuaded his supervisors to agree to his admission to the doctoral program, focusing on Condensed Matter Physics offered by the Department of Physics, Nanjing University. During his Ph.D. study, his research innovations won him many honorable awards - the Nanjing University Rising Star Science Award, the Chinese Academy of Sciences, the "Motorola" scholarship, and the "Hua Ke" scholarship. But, most significantly, his doctoral thesis was rated as an outstanding doctoral thesis by Nanjing University, which marked his doctoral journey with flying colors in 2000.

After completing his Ph.D. study in 2000, his name became known to academic managers of Henan province. He was awarded the Henan Outstanding Youth Science Fund and appointed to be a cross-century academic and technical leader in Henan Province. He was selected into the Henan Provincial Colleges and Universities Innovative Talent Training Project in 2002; invited to pay a visit to the Department of Physics, Hong Kong University of Science and Technology twice in 2001 and 2003; and nominated to participate in JSPS post-doctoral exchange research at the Japan Institute of Material and Material Research from 2004 to 2006.

During his research life, he has completed more than 20 scientific research projects at national, provincial and ministerial levels mainly concerning the preparation of perovskite structure ferroelectric and photoelectric thin films, heterostructures and nanomaterials, microstructure characterization and photoelectric properties such as the SrBi2Ta2O9 ferroelectric film nonlinear optical response and optical limiting characteristics, TiO2 nanotube formation mechanism, hexagonal phase YMnO3 and orthorhombic phase YMnO3 film preparation new technology and optical characteristics, to name a few. On top of that, Zhang carried out systematic in-depth research work. For example, he found out the third-order nonlinear optical properties of YMnO3 film, explored that SrBi2Ta2O9 film has a significant optical limiting effect, and clarified the formation mechanism of TiO2 nanotubes. All of which achieved innovative results. His outstanding findings have been published in more than 180 papers, of which 110 have been indexed by SCI and EI and cited more than 1300 times.

His sea-deep knowledge and research contributions made no one other than him responsible for establishing Henan Provincial Key Laboratory of Photovoltaic Materials and Henan Provincial University Optoelectronic Information Technology Key Subject Open Laboratory.
