英文摘要： This research proposes to investigate synthesis and characterization of high-performance organic sensitizer and nanocrystalline semiconductor materials for energy conversion, aiming at developing high-efficiency, low-cost dye-sensitized solar cells (DSCs) based on novel hybrid photoanode structures. The research will involve designing the novel NIR dyes and metal oxide semiconductor with the corresponding energy alignment. Using novel hybrid and tandem DSCs that consist of both visible dyes and NIR dyes, we broaden the absorption spectra and improve the harvest of light. Meanwhile, we will carry out studies of nanocrystalline semiconductor materials with mesoporous pores and suitable surface area. Therefore, the fundamental studies of 'structure-function' system are based on composite materials, exploring ways to further improve the conversion efficiency of DSCs. The in-depth study on the photo-to-electric mechanism also paves the way for improving the theoretical basis of photovoltaic performance. Research findings from novel configuration of hybrid and tandem DSCs will play an important role in accelerating commercialization of DSCs, thus contributing to advancement of solar cell research in China and raising its competitiveness in the international market.
