中文摘要： 染料敏化太阳能电池（DSSC）的低光电转换效率是限制其成为未来太阳能电池主流技术的瓶颈问题。光阳极薄膜作为DSSC核心组件之一，对其进行纳米化结构形貌调控是解决该难题的重要途径。本项目基于材料辐照研究的新成果，创新提出利用低能量高密度He等离子体辐照技术，调制纳米绒毯结构的光阳极薄膜，以期提升DSSC光电转换效率。据此，项目拟研究纳米绒毯TiO2光阳极薄膜的辐照调制/退火工艺、绒毯层形成演化机理，以及薄膜结构与其性能、电池性能相关性等若干基础问题。研究旨在为低能量高密度He等离子体辐照制备纳米毯光阳极薄膜的潜在应用提供技术探索与工艺基础、深化对离子辐照诱导材料纳米化的研究。值得强调的是，通过项目实施，有望开发一类新型的纳结构薄膜材料及一种实用的材料表面纳米化技术。

英文摘要： Dye-sensitized solar cell (DSSC) is one of the most promising candidates to the future solar cells due to its low cost and easy fabrication. Photoanode films is one of key components of DSSC and its nano-scaled design and modulation opens a door to improving photo-electric conversion efficiency of DSSC.In this proposal,through introducing new technology in the field of materials irradiation, we propose a novel research plan, namely, nano-fuzz blanket photoanode films modulated by high density-low energy He plasma irradiation, in order to obtain high conversion efficiency of DSSC.The mian research contents of our plan include: the fundamental experiment research of photoanode films iradiated by high density-low energy He plasma, the correlationship between photo-electric properties of DSSC and microstructure of nano-fuzz balnket photoanode films, and the microscopic growth mechanisms of nano-fuzz blanket photoanode films, etc.The aim of our research is to provide technological foundation and theoretical guidance for the application of nano-fuzz blanket photoanode films. Meanwhile, our research could contribute to understanding the microscopic mechanism of surface nano-structure induced by high density-low energy He plasma irradiation. It should be noted that, our research has novel idea and interdisciplinarity characteristic. If our proposal can be performed successfully, a novel nano-structured film and a practical nano-technology will be developed, which can be further transplanted in other application fields of nano-thin films.
