英文摘要： In this project, organic fibrous nanocrystals and inorganic nanocrystals will be used as templates for the grafting, coordination or adsorption of inorganic and organic quantum dots (QDs), respectively. Ordered interpenetrating networks of organic/inorganic nanocrystal hybrids will be obtained by inducing growth or aggregation methods. The interface and electronic properties of organic/inorganic nanocrystals will be carefully controlled to improve their compatibility and electric contact at the interface. In-situ growth of organic/inorganic nanocrystal hybrids from solution will be explored to obtain long-range ordered organic/inorganic semiconductor heterojunctions in a controlled manner. The influence of the aggregation structure and interface property of organic/inorganic nanocrystal hybrid on their photovoltaic properties will be studied to achieve the breakthrough of the power conversion efficiency of organic/inorganic hybrid solar cells. This research will provide new strategies to solve problems of organic/inorganic thin film solar cells, and will contribute to the technological innovation and progress of solar power industry in China.
