项目摘要

Since Gratzel and coworkers developed a new type, solar cell based on the nanocrystalline TiO2 electrode sensitized to visible light with dye molecules, the goal of efficient solar cells of the next generation has focused on dye-sensitized photochemical solar cells. Dye-sensitized solar cells are most expected to be one, of the next-generation solar cells because of their simple fabrication and low-cost manufacture. In this study, in order to increase the photovoltaic conversion efficiency (η) of the dye-sensitized solar cell, the photochemical performance of the dye-sensitized solar cell comprised of the TiO_2 electrode prepared by (low-temperature plasma/ion-implantation) continuous treatment using plasma irradiation equipment and sputter ion gun Or ion implantation equipment has been, investigated. The cells comprised of the Ar plasma irradiated and N ion-implanted TiO_2 electrodes showed a higher short-circuit photocurrent density (Jac) and a larger fill factor (ff)I and higher conversion efficiency, compared with the original cell. The Jsc of the cells increased with increasing the amount of implanted N ions because the amount of oxygen vacancy in the cells increased with increasing the amount of implanted N ions, therefore, the number of conduction electrons in the cells increased. It was recognized that the performance of the cell comprised of the N ion-implanted TiO_2 electrode was influenced strongly by the amount of implanted N ions. Also, N ion-implanted and Ar plasma irradiated TiO_2 electrode showed a higher Jsc and conversion efficiency depending upon the treatment conditions. It was recognized that the performance of the cell comprised of the N ion-implanted TiO_2 electrode was influenced strongly by the conditions of plasma irradiation.

自从 Gratzel 和同事开发出一种基于纳米晶 TiO2 电极并通过染料分子对可见光敏感的新型太阳能电池，下一代高效太阳能电池的目标就集中在染料敏化光化学太阳能电池上。染料敏化太阳能电池因其制造简单且制造成本低而最有希望成为下一代太阳能电池之一。本研究为了提高染料敏化太阳能电池的光电转换效率(η),对采用等离子体辐照设备和溅射离子枪或离子注入设备进行(低温等离子体/离子注入)连续处理制备的TiO_2电极组成的染料敏化太阳能电池的光化学性能进行了研究。与原始电池相比，由Ar等离子体照射和N离子注入TiO_2电极组成的电池表现出更高的短路光电流密度（Jac）和更大的填充因子（ff）I以及更高的转换效率。电池的Jsc随着N离子注入量的增加而增加，因为随着N离子注入量的增加，电池中氧空位的数量增加，因此电池中传导电子的数量增加。人们认识到，由N离子注入的TiO_2电极组成的电池的性能受到注入的N离子的量的强烈影响。此外，根据处理条件，N离子注入和Ar等离子体照射的TiO_2电极表现出更高的Jsc和转换效率。人们认识到，由N离子注入的TiO_2电极组成的电池的性能受到等离子体辐射条件的强烈影响。
