在光伏太阳能电池中，减反射涂层对于减少光反射损耗至关重要。单层氟化镁（MgF2）增透涂层通常用于薄膜CIGS太阳能电池。根据光学，这种涂层只能在狭窄的光谱范围内有效。进一步减少反射损耗可能需要最佳的单层或多层涂层。因此，我们优化了含有CIGS吸收层的CIGS太阳能电池的单层和双层抗反射涂层的折射率和厚度，这些CIGS吸收层具有：(i)均匀带隙，（ii）线性渐变带隙，或（iii）非线性渐变带隙。与单层增透膜相比，最优双层增透膜的相对增强可达1.83%。
Antireflection coatings are vital for reducing loss due to optical reflection in photovoltaic solar cells. A single-layer magnesium fluoride (MgF2) antireflection coating is usually used in thinfilm CIGS solar cells. According to optics, this coating can be effective only for a narrow spectral regime. Further reduction of reflection loss may require an optimal single-layer or multi-layer coating. Hence, we optimized the refractive indices and thicknesses of single- and double-layer antireflection coatings for CIGS solar cells containing a CIGS absorber layer with: (i) homogeneous bandgap, (ii) linearly graded bandgap, or (iii) nonlinearly graded bandgap. A relative enhancement of up to 1.83% is predicted with an optimal double-layer antireflection coating compared to the efficiency with a single-layer antireflection coating.
