Abstract

Solar plasmonics absorbers have received outstanding interest from nanotechnology. However, they have small efficiency. To overcome this challenge, we have used two ways in this proposed paper. In the first method, two types of nanoparticle including gold and silver are used on the superstate silica layer in the form of an insulating metal structure. Additionally, to analyze the structure, finite difference time domain (FDTD) is proposed. As a result, at all wavelengths, more than 50% of sunlight will be absorbed. On the other hand, by combining the light to the boundary between nanoparticles and insulation and applying optimization method in Lumerical software, surface plasmons will be stimulated and the possibility of modeling in nanodimensions is provided. It was clearly obvious that by increasing the diameter of the nanoparticles from 10 to 15 nm the amount of light absorption is increased, and by reaching the diameter nanoparticles to 20 nm, light absorption decreases. Regarding to the standard account (100 mW cm², AM 1.5), maximum short-circuit current of 20 mA, open-circuit voltage of 0.65 V and filling coefficient 60 percent, the amount of light conversion will be 8.45%.

使用PSO算法和FDTD方法对纳米结构等离子体太阳能吸收体进行宽带光吸收增强的智能逆变器

摘要

太阳能等离子体吸收器已受到纳米技术的极大兴趣。但是，它们的效率很低。为了克服这一挑战，我们在这篇提议的论文中使用了两种方法。在第一种方法中，包括金和银的两种纳米粒子以绝缘金属结构的形式被使用在超状态二氧化硅层上。此外，为了分析结构，提出了有限差分时域（FDTD）。因此，在所有波长下，都会吸收超过 50% 的阳光。另一方面，通过将光结合到纳米粒子和绝缘体之间的边界，并在 Lumerical 软件中应用优化方法，将激发表面等离子激元，并为纳米维度建模提供了可能性。很明显，通过将纳米粒子的直径从 10 nm 增加到 15 nm，光吸收量增加，而当纳米粒子直径达到 20 nm 时，光吸收减少。关于标准帐户（100 mW cm²，AM 1.5)，最大短路电流20mA，开路电压0.65V，填充系数60%，光转换量8.45%。
