Reducing the surface reflectivity of silicon substrates is essential for preparing high-performance Si-based solar cells. We synthesized pyramid-nanowire-structured Si (Si-PNWs) anti-reflection substrates, which have excellent light-trapping ability (<4% reflectance). Furthermore, diethyl phthalate (DEP), a water-insoluble phthalic acid ester, was applied to optimize the Si-PNWs/PEDOT:PSS interface; the photoelectric conversion efficiency of heterojunction solar cells was shown to increase from 9.82% to 13.48%. We performed a detailed examination of the shape and optical characteristics of Si-PNWs, as well as associated photoelectric performance tests, to investigate the origin of performance improvements in Si-PNWs/PEDOT:PSS heterojunction solar cells (HSCs).
降低硅衬底的表面反射率对于制备高性能硅基太阳能电池至关重要。我们合成了具有优异光捕获能力（反射率<4%）的金字塔-纳米线结构硅（Si-PNWs）抗反射衬底。此外，应用了邻苯二甲酸二乙酯（DEP），一种水不溶性邻苯二甲酸酯，来优化Si-PNWs/PEDOT:PSS界面；结果表明，异质结太阳能电池的光电转换效率从9.82%提高到了13.48%。我们对Si-PNWs的形状和光学特性进行了详细研究，并进行了相关的光电性能测试，以探究Si-PNWs/PEDOT:PSS异质结太阳能电池（HSCs）性能提升的根源。
