教学  教学理念：让学生花尽可能少的时间和精力而获得尽可能多的宝贵的知识。讲课尽量做到通俗易懂、生动有趣。给本科生讲授过《材料物理性能》、《新能源材料与器件专业英语》、《英语单词识记》（全校公选课）、《力学》、《光学》；给研究生讲授过《光电子学》、《光伏材料与太阳能电池》。

 科研    主要进行光伏薄膜材料及太阳能电池研究，包括钙钛矿薄膜太阳电池Perovskite thin film solar cell、氧化铜薄膜太阳电池CuO thin film solar cell、新型光伏薄膜材料和结构New photovoltaic thinfilm materials and structure. 重要科学创新：实现了非晶/纳晶薄膜材料（CuO:Se复合材料薄膜）的光生载流子扩散长度（3.14 mm）远大于单晶材料的光生载流子扩散长度（p型单晶硅为1.95 mm）。Important scientific innovation: for the first time, it has been realized that the photogenerated carrier diffusion length (3.14 mm) ofamorphous/nanocrystalline film material (CuO:Se composite film) is much larger than that of monocrystalline material (p-Si 1.95 mm).

            业余时间从事英语单词识记研究以解决英语单词难记的问题，首次提出了英语单词的“字”、“词”概念。采用以字带词的方法，容易和高效地识记大量英语单词，快速突破词汇关。
