摘要

二氧化钛(TiO2)是一种用途广泛的材料,应用范围从光催化到制药。最近,二氧化钛正在研究在可再生能源领域的潜在应用。其中一个应用是新一代太阳能电池,称为染料敏化太阳能电池(DSSC),其中二氧化钛纳米粒子可以用作电极材料。DSSC的太阳能转换效率明显低于典型的Si基光伏电池,但在单位表面积成本更低方面具有显著优势。采用常压流化床等离子体反应器对TiO2纳米颗粒进行表面改性。等离子体诱导的TiO2纳米粒子的形态变化与相应的结构和电子变化相关。等离子体处理TiO2纳米粒子的DSSC显示出光伏性能的改善。

Plasma surface modification of TiO2 nanoparticles for Dye-Sensitized Solar cell (DSSC) application
Titanium-di-oxide (TiO2) is a very versatile material with applications ranging from photocatalysis to pharmaceuticals. More recently TiO2 is being investigated for potential applications in the field of renewable energy. One such application is in a new generation of solar cells called Dye-Sensitized Solar cells (DSSC), where TiO2 nanoparticles can be used as an electrode material. The solar energy conversion efficiency of DSSC is significantly lower than that of a typical Si based photovoltaic cell, but it has a significant advantage in terms of more reduced cost per unit surface area. An atmospheric-pressure fluidized bed plasma reactor was used to modify the surface properties of TiO2 nanoparticles. Plasma induced morphological changes of the TiO2 nano-particles were correlated with the corresponding structural and electronic changes. DSSC with plasma treated TiO2 nanoparticles demonstrated an improvement in photovoltaic performance.
