In today's world, scientific development is tremendously strengthened by imitating natural processes. This development remarkably validates progressive and efficient operation of multifunctional thin films in variable ecological circumstances. We use TFCalc thinfilm software, a reliable and trustworthy simulation tool, to design antireflective (AR) coatings for solar cells that can operate in varying environmental conditions and can be functional according to user-defined conditions. Silicon nearly reflects 36% light in the 550 nm wavelength region, causing a significant loss in solar cell efficiency. We used silicon as the substrate on which we designed and fabricated a trilayer inorganic oxide AR thin films, and this reduced it reflectance to <4% in the 300~800 nm wavelength range. Because of their distinguishing physical physiognomies, we used a combination of different inorganic oxides, comprising high-, low-, and medium-refractive indices, to model AR coatings in the desired wavelength range. Experimental implementation of the designed AR thin films in the present study unlocks new techniques for production of competent, wideband-tunable AR coatings that are applicable in high-performance photovoltaic applications.
在当今世界，通过模仿自然过程极大地推动了科学发展。这种发展显著验证了多功能薄膜在不同生态环境中的高效运行。我们使用TFCalc薄膜软件（一种可靠且值得信赖的模拟工具）来设计可在不同环境条件下运行且能根据用户定义条件发挥功能的太阳能电池抗反射（AR）涂层。硅在550纳米波长区域会反射近36%的光，这会导致太阳能电池效率大幅损失。我们以硅为基底，在其上设计并制备了三层无机氧化物AR薄膜，在300~800纳米波长范围内将其反射率降低至<4%。由于不同无机氧化物具有独特的物理特性，我们使用了包括高、低、中折射率的不同无机氧化物组合，以在所需波长范围内模拟AR涂层。本研究中设计的AR薄膜的实验实施为生产适用于高性能光伏应用的高效、宽带可调谐AR涂层开辟了新技术。
