We report on a theoretical investigation on the influence of different wavelength scale periodic grating architectures on dye sensitized solar cell (DSC). A broadband absorption enhancement is expected in such solar cells thanks to diffraction effects produced by these structures. Their optimal size has been analyzed in terms of pitch grating, height and position along the solar cell layers. Numerical simulations indicate that nanostructuring the interface between the active and the electrolyte layer by integrating a dielectric grating produces an absorption enhancement of 23.4%. The presented results have been also evaluated in view of feasible realistic structures compatible with low cost soft lithographic techniques.
我们报道了一项关于不同波长尺度周期性光栅结构对染料敏化太阳能电池（DSC）影响的理论研究。由于这些结构产生的衍射效应，预计此类太阳能电池会有宽带吸收增强。已根据光栅间距、高度以及沿太阳能电池层的位置对其最佳尺寸进行了分析。数值模拟表明，通过集成介电光栅对活性层与电解质层之间的界面进行纳米结构化处理，可使吸收增强23.4%。还针对与低成本软光刻技术兼容的可行实际结构对所呈现的结果进行了评估。
