中文摘要：
光生电荷转移性质是决定光电功能体系性能的关键因素．近年来，由于纳米结构材料的引入使得大多数光电功能体系的光电活性（或性能）显著提高，例如：将TiO2纳米多孔电极引入到染料敏化太阳能电池后，其光电转换效率获得了突破性的提高．
英文摘要：
The photo-generated charge transfer characteristics of n-Si/TiO2/Azo pigment in micrometer regions was studied by means of kelvin probe force microscopy（KFM） technique.The results showed that the photo-generated electrons of Azo pigment particles transferred to n-Si/TiO2 under illumination,and a photo-induced p-n-p structure in micro-scale was observed for the first time.This result indicates that photo-generated charge transfer characteristics of organic/inorganic complex in nano-scale can be observed directly by KFM.
