Abstract

Perovskite solar cells (PSCs) are hot topics in the energy community due to their high absorption capacity, simple fabrication process, and low production costs. However, to enhance the optoelectronic performance of photonic devices, it is essential to advance high-quality photon management and superior optical design. This study utilizes optical metasurfaces to modulate light focusing and enhance light absorption. Single-hemispherical and double-hemispherical metasurfaces are added to planar conventional PSCs to improve the absorption of the device respectively, thus enhancing photovoltaic conversion efficiency. The integrated irradiance of perovskite is calculated for evaluating the light absorption capacity of the cells, and three-dimensional optical and semiconductor finite element method simulations are conducted to optimize structural parameters. Ultimately, compared with the PSC planar, the short-circuit current density is increased by 20.5 %, and the power conversion efficiency is improved by 22 % for the PSC integrated with the double-hemispherical metasurface. This proposed design exhibits certain angular stability and polarization insensitivity, making it widely applicable in the photovoltaic industry and providing crucial support for the further advancement of photovoltaic technology.

基于球形超表面的钙钛矿太阳能电池性能增强研究

过氧化物太阳能电池（PSC）具有吸收能力强、制造工艺简单、生产成本低等优点，是能源界的热门话题。然而，要提高光子器件的光电性能，必须推进高质量的光子管理和卓越的光学设计。本研究利用光元表面来调节光聚焦和增强光吸收。将单半球形和双半球形元表面添加到平面传统 PSC 中，分别改善器件的吸收，从而提高光电转换效率。计算了包晶的综合辐照度，以评估电池的光吸收能力，并进行了三维光学和半导体有限元法模拟，以优化结构参数。最终，与平面 PSC 相比，集成了双半球形元表面的 PSC 的短路电流密度提高了 20.5%，功率转换效率提高了 22%。该设计方案具有一定的角度稳定性和极化不敏感性，可广泛应用于光伏产业，为光伏技术的进一步发展提供重要支持。
