In this study, high energy conversion efficient dye-sensitized solar cells (DSSCs) were successfully fabricated by attaching a double anti-reflection (AR) layer, which is composed of a subwavelength moth-eye structured polymethyl methacrylate (PMMA) film and a polydimethylsiloxane (PDMS) film. An efficiency of up to 6.79% was achieved. The moth-eye structured PMMA film was fabricated by using an anodic aluminum oxide (AAO) template which is simple, low-cost and scalable. The nano-pattern of the AAO template was precisely reproduced onto the PMMA film. The photoanode was composed of Titanium dioxide (TiO₂) nanoparticles (NPs) with a diameter of 25 nm deposited on the fluorine-doped tin oxide (FTO) glass substrate and the sensitizer N3. The double AR layer was proved to effectively improve the short-circuit current density (JSC) and conversion efficiency from 14.77 to 15.79 mA/cm² and from 6.26% to 6.79%, respectively.
在本研究中，通过附着由亚波长蛾眼结构聚甲基丙烯酸甲酯（PMMA）薄膜和聚二甲基硅氧烷（PDMS）薄膜组成的双层抗反射（AR）层，成功制备了高能量转换效率的染料敏化太阳能电池（DSSC）。实现了高达6.79%的效率。蛾眼结构的PMMA薄膜是使用阳极氧化铝（AAO）模板制备的，该模板简单、低成本且可扩展。AAO模板的纳米图案被精确复制到PMMA薄膜上。光阳极由沉积在氟掺杂氧化锡（FTO）玻璃基板上的直径为25nm的二氧化钛（TiO₂）纳米颗粒（NP）和敏化剂N3组成。双层AR层被证明能有效提高短路电流密度（JSC）和转换效率, 分别从14.77提高到15.79 mA/cm²，从6.26%提高到6.79%。
