论文摘要
在这项研究中，在量子点敏化的太阳能电池（QDSC）中研究了氟化镁（MGF2）抗反省（AR）层的影响。通过热蒸发方法生长具有主要大小为20 nm的MGF2纳米颗粒，并在氟掺杂的氧化锡（FTO）底物的前侧形成薄层。为了研究AR层对太阳能电池效率的影响，该底物在CDS QDSC中使用。在这种常规的QDSC结构中，将TIO2纳米晶体（NC）应用于FTO底物，然后用CDS量子点（QDS）敏感。根据结果，具有MGF2 AR层的QDSC表示最大功率转换效率（PCE）为3％。与没有AR层的参考细胞相比，该效率提高了约47％。原因归因于AR层的存在以及从太阳能电池表面反射的入射光的还原。
In this research, the effect of Magnesium Fluoride (MgF2) Anti-Reflection (AR) layer was investigated in quantum dot sensitized solar cells (QDSCs). MgF2 nanoparticles with the dominant size of 20 nm were grown by a thermal evaporation method and a thin layer was formed on the front side of the fluorine-doped tin oxide (FTO) substrate. In order to study the effect of the AR layer on the efficiency of solar cells, this substrate was utilized in CdS QDSCs. In this conventional structure of QDSC, TiO2 nanocrystals (NCs) were applied on the FTO substrate, and then it was sensitized with CdS quantum dots (QDs). According to the results, the QDSCs with MgF2 AR layer represented the maximum Power Conversion Efficiency (PCE) of 3%. This efficiency was increased by about 47% compared to the reference cell without the AR layer. The reason is attributed to the presence of the AR layer and the reduction of incident light reflected from the surface of the solar cell.
