IntroductionI am committed to the research of interface regulation of organic solar cells.I have achieved a series of innovative research results in the design and synthesis of new interface molecular materials, morphology characterization, interface modification performance, and photovoltaic device interface engineering research, solving the problem of energy loss caused by the mismatch of semiconductor and electrode contact interface energy levels in photovoltaic cells, and promoting the industrialization of organic polymer solar cells and their application in the field of clean energy.I have published many research papers in high-level academic journals such as Science, and my research results have attracted great attention from international peers. My articles have been selected as very important papers for many times, and related work has been reported by international science and technology media such as Science Daily and Tech the Day. In terms of student training, I was selected as an excellent master's and doctoral dissertation instructor at Beijing University of Chemical Technology; I have trained a group of outstanding undergraduates and graduate students.Among them, three graduate students won national scholarships; one graduate student and three undergraduates were selected as outstanding graduates of Beijing; four graduate students won outstanding doctoral and master's degree dissertations of Beijing University of Chemical Technology; guided many undergraduates to participate in the Da Chuang and Mengya Cup competition projects, and won school-level and college-level awards.
