研究方向及讲授课程

主要从事有机/无机杂化太阳能电池、量子点太阳能电池和量子点敏化光电极的理论和实验研究。在理论方面,取得的主要成果是为双层聚合物/TiO2太阳能电池的光强度调制的电流谱(Intensity modulated photocurrent spectroscopy)建立了相应的理论模型,用于定量分析激子在聚合物/TiO2界面处的分离速率,定性分析电池内部电荷传输机制的转变以及输运快慢。在实验室方面主要包括:通过一些实验方法提高了量子点(包括CdSAg2S等)敏化的TiO2纳米管阵列的光电转换效率;通过新方法将量子点敏化的TiO2纳米管分散进体异质结聚合物太阳能电池中提高了电池的光电转换效率。目前已经在J Mater ChemNanotechnology J. Phys. Chem. CNanoscale Res LettJ. Mater. Sci等国际期刊上发表SCI论文15篇。
