In this work, photovoltaic devices with CdSe QDs-photoanodes doped Cu and Mn metals using the Successive ionic layer adsorption and reaction method for high-efficiency performance. Here, the molar dopant of Cu was studied from 0% to 5%, while Mn molar was changed between 0% and 40% to optimize conditional experiment. This result shows an increase of current density in both CdSe doped on Cu and Mn as a result of the enhancing light absorption and reducing recombination when a ZnS layer was used as passivation. In fact, a high 4.24% of efficiency for CdSe doped on Cu and 3.9% of efficiency for CdSe doped on Mn were archived comparing with pure CdSe QDs.

使用铜和锰掺杂的硫化镉量子点增强量子点敏化太阳能电池中的光吸收和电荷复合控制

在这项工作中，具有 CdSe QDs-光阳极掺杂 Cu 和 Mn 金属的光伏器件使用连续离子层吸附和反应方法获得高效性能。在这里，研究了 Cu 的摩尔掺杂剂从 0% 到 5%，而 Mn 摩尔在 0% 和 40% 之间变化以优化条件实验。该结果表明，当使用 ZnS 层作为钝化层时，由于光吸收增强和复合减少，Cu 和 Mn 上掺杂的 CdSe 中的电流密度增加。事实上，与纯 CdSe QD 相比，Cu 上掺杂的 CdSe 的效率提高了 4.24%，Mn 上掺杂的 CdSe 的效率提高了 3.9%。
