Abstract

The design and optimization of a nanostructured antireflective coatings for Si solar cells were performed by using response surface methodology (RSM). RSM was employed to investigate the effect on the overall optical performance of silicon solar cells coated with three different nanoparticle materials of titanium dioxide, aluminum oxide, and zinc oxide nanostructures. Central composite design was used for the optimization of the reflectance process and to study the main effects and interactions between the three process variables: nanomaterial type, the radius of nanoparticles, and wavelength of visible light. In this theoretical study, COMSOL Multiphysics was utilized to design the structures by using the wave optics module. The optical properties of the solar cell’s substrate and the three different nanomaterial types were studied. The results indicated that ZnO nanoparticles were the best antireflective coating candidate for Si, as the ZnO nanoparticles produced the lowest reflection values among the three nanomaterial types. The study reveals that the optimum conditions to reach minimum surface reflections for silicon solar cell were established by using ZnO nanoparticles with a radius of ~38 nm. On average, the reflectance reached ~5.5% along the visible spectral range, and approximately zero reflectance in the 550–600 nm range.
基于响应面法的硅太阳电池减反射涂层性能设计与优化
采用响应面法(RSM)对硅太阳能电池纳米结构减反射涂层进行了设计和优化。采用RSM方法研究了二氧化钛、氧化铝和氧化锌纳米结构对硅太阳能电池整体光学性能的影响。采用中心复合设计对反射过程进行优化,研究了纳米材料类型、纳米颗粒半径和可见光波长三个过程变量之间的主要影响和相互作用。在本理论研究中,利用COMSOL Multiphysics软件对波光学模块进行结构设计。研究了太阳能电池衬底的光学性能和三种不同类型的纳米材料。结果表明,ZnO纳米粒子是Si的最佳减反射涂层,其反射值在三种纳米材料中最低。研究表明,采用半径为~38 nm的ZnO纳米颗粒,确定了达到硅太阳电池表面反射最小的最佳条件。在可见光光谱范围内,反射率平均达到~5.5%,在550 ~ 600 nm范围内反射率近似为零。
