| 与硅太阳能电池和染料敏化太阳能电池相比，量子点太阳能电池成本低、性能优越、具有更广阔的前景，而采用固态电解质制备全固态量子点太阳能电池的研究更是太阳能电池的未来发展方向。如何改进光电极的电子传输和固体电解质的填充是提高电池性能的关键所在。本项目通过两步阳极氧化法制备出TiO2纳米管阵列作为电子的超快传输通道，首先采用连续离子层吸附与反应法在TiO2纳米管阵列表面沉积CdS核层量子点，通过离子置换法构建核壳结构量子点作敏化剂，然后通过电化学法在纳米管中原位聚合PEDOT作为空穴的传输通道，制备出全固态核壳量子点敏化TiO2纳米管阵列太阳能电池，并研究核壳量子点和PEDOT的制备条件对太阳能电池光吸收特性、电荷迁移特性以及光电转换效率的影响，揭示TiO2纳米管阵列/核壳量子点/PEDOT之间的电荷转移与输运机制。本项目的研究成果对于新型太阳能电池微观结构的设计和研究具有重要的科学意义。 |

| Compared with the silicon solar cells and the dye sensitized solar cells, the quantum dot (QD) solar cells have the advantages of lower cost, better performance and wider applications, and one trend is to develop the all-solid-state QD solar cells with solid electrolytes. The key to the performance of solar cells lies in how to improve the electron transport of the photoelectrode and the filling of solid electrolytes. In this research, the two-step anodic oxidation method was utilized to prepare the TiO2 nanoarray as the ultrafast transmission channel for electrons, and CdS QDs were deposited on the nanoarrays by successive ionic layer adsorption and reaction process, followed by the formation of the core-shell QDs as the sensitizer with the ion replacement method. Then PEDOT, which acts as the transmission channel for holes, was prepared in the nanotubes by in-situ polymerization via the electrochemical process. The all-solid-state QD-sensitized TiO2 nanoarray solar cells were thus fabricated. Effects of the fabrication conditions for the core-shell QDs and PEDOTs were studied on the absorption properties, charge transfer and photoelectric conversion efficiency of the solar cells, and the mechanism for charge transfer and transport were revealed in the TiO2 nanoarrays/core-shell QDs/PEDOTs. This finding is of great scientific significance to the microstructure design and study of novel solar cells. |
