摘要：新能源领域日新月异，太阳能电池的开发更是突飞猛进，染料敏化太阳能电池（Dye-Sensitized Solar Cell,DSSC）作为新一代薄膜太阳能电池，具有制备工艺简单、价格低廉的优点，极具应用前景。但与工艺较为成熟的硅基和多元复合薄膜太阳能电池相比，该类电池的光电转化效率还不高，为此，发展光阳极成为关键。本课题通过重力/垂直沉积法生长光子晶体，用前驱体渗透处理后，烧结得到反蛋白石结构光子晶体，再用丝网印刷TiO2膜制备光阳极，从而改进了传统染料电池的电极结构，利用反蛋白石结构比表面积大和带隙散射效应，以及一定的调节光传播能力，达到了对光的“回收”利用。通过选取ITO导电玻璃和柔性材料碳纤维为光阳极基底进行比较，制备所得电池电极理论上能提高对光的散射和降低折射率，从而提高光电转换效率，以期得到较优异性能的TiO2基染料敏化薄膜太阳能电池，提高其应用价值。80895

Study on Structure Control of TiO2 - based Thin Film Solar Cell Based on Photonic Crystal

Abstract: New energy field with each passing day, the development of solar cells is by leaps and bounds。 Dye-sensitized solar cell (DSSC), as a new generation of thin film solar cells, has the advantages of simple preparation process and low cost, and has great application prospect。  But compared to silicon-based solar cells and multi-compound thin film solar cells, the kind of battery photoelectric conversion efficiency is still not high。 At present, in order to solve the problem of inefficient conversion, the development of light anode has become the key。 In this paper, the photonic crystals is grown by vertical deposition method, and the photonic crystals were prepared by sintering with the precursor。 The TiO2-based photocathode was fabricated by screen printing, and the electrode structure of the traditional dye cells is improved。 By using the anti-opal structure ratio surface area and bandgap scattering effect, as well as a certain degree of regulation of light transmission capacity, to the light of the "recycling" use。 By selecting ITO conductive glass and flexible material carbon fiber as the photocathode substrate, the prepared battery electrode can theoretically improve the light scattering rate and reduce the light refractive index, thereby improving the photoelectric conversion efficiency and obtaining the better performance of TiO2-based DSSC。
