摘要
人类面临着有限常规能源和环境破坏严重的双重压力,太阳能己经成为越来越值得关注的重要能源。染料敏化太阳能电池(DSCs)是一种具有广泛应用前景的新一代太阳能电池,具有成本低,制备工艺简单等优势。一般而言,它由纳米结构金属氧化物半导体的光阳极、染料敏化剂,电解质和对电极等几个部分组成。纳米TiO2薄膜具有特殊的结构、性能和半导体光催化活性等特点,具有广阔的应用前景和重要的理论研究价值,是染料敏化太阳能电池(DSCs)光阳极的首选材料。本文介绍了染料敏化太阳电池中TiO2光阳极的研究现状,对TiO2光阳极常用的制备方法进行了综述,提出获得具有高比表面积、快速电子传输、有效抑制电荷的复合和优越的光收集效率的薄膜将是未来TiO2光阳极研究的方向。
Owing to the double pressures of limited regular energy and severely-destroyed environment,solar energy was more and more worthy of attention. Dye-sensitized solar cells（ DSCs） were one of the most promising new generation photovoltaic devices,which had the advantages of high cost-efficiency ratio,low weight,and simple fabrication technique. In general,solar cells consisted of photo-anodes made of nano-structured TiO2 films,dye-sensitizers,electrolytes and counter-electrodes. Nano TiO2 was important in many fields due to its special structure,performance and excellent semiconductor photocatalytic characteristics,and it was the preferred materials of DSCs. The development and application of TiO2 photoanodes in dye-sensitized solar cells（ DSCs） were reviewed in this article. The preparation methods for TiO2photo-anodes were summarized. Fabricating TiO2 porous films with high specific surface area,quick charge transport,excellent light harvesting and efficient suppression of charge recombination was the direction of further development.
