本研究的目的是在宽光谱范围（400-1200 nm）内降低玻璃基板的反射率，而在近红外区域内不具有高反射率。在制备多孔SiO2/MgF 2双层叠层（DLAR）薄膜结构之后，添加了叠层型硅基叠层电池。与仅具有硅基叠层太阳能电池相比，当将多孔SiO2/MgF 2DLAR薄膜应用于硅基叠层太阳能电池时，短路电流密度提高了6.82%。这项研究表明，多孔SiO2/MgF 2DLAR薄膜结构提供了在宽光谱范围（400-1200 nm）内的反射特性，而在近红外波长处没有高反射率。
The purpose of this study is to reduce the glass substrate reflectivity over a wide spectral range (400-1200 nm) without having high reflectivity in the near-infrared region. After making porous SiO₂/MgF₂ double-layer antireflection (DLAR) thin film structure, the superstrate-type silicon-based tandem cells are added. In comparison to having only silicon-based tandem solar cells, the short-circuit current density has improved by 6.82% when porous SiO₂/MgF₂ DLAR thin film is applied to silicon-based tandem solar cells. This study has demonstrated that porous SiO₂/MgF₂ DLAR thin film structure provides antireflection properties over a broad spectral range (400-1200 nm) without having high reflectivity at near-infrared wavelengths.
