We in this paper propose a high-performance design using bio-inspired metamaterials for multilayered perovskite solar cell (MPSC) plates. The static bending and free vibrational responses of the newly designed MPSC panels with the presence of the triply periodic minimal surface (TPMS) substrate are subsequently investigated numerically. The displacements of the present plate model are then approximated by five-variable higher-order shear deformation theories (HSDTs). The weak forms are established for both the static bending and free vibration problems and subsequently derive the discrete forms using the NURBS-based isogeometric approach. To enhance the operational efficiency of solar panels in challenging environments, we integrate advanced lightweight architectures based on bio-inspired TPMS structures as a substrate layer into the original solar panel design. In this research, three widely employed TPMS structures: Primitive, Gyroid, and I-graph and Wrapped Package-graph (IWP), are examined in conjunction with two functional grading patterns implemented through the thickness direction. For the first time, the static bending performance of MPSC plates integrated into a TPMS-based substrate layer and subjected to wind pressure as well as thermal conditions is comprehensively studied. In addition, the influence of several significant factors on the free vibration behavior of MPSC plates is also elucidated. The findings show a promising and intriguing design avenue, particularly in the application of high-performance metamaterials to address contemporary challenges in renewable energy usage and environmental protection.

采用仿生基板的太阳能电池板的等几何分析


我们在本文中提出了一种使用仿生超材料进行多层钙钛矿太阳能电池（MPSC）板的高性能设计。随后对新设计的 MPSC 面板在三周期最小表面 (TPMS) 基板的存在下的静态弯曲和自由振动响应进行了数值研究。然后通过五变量高阶剪切变形理论（HSDT）来近似当前板模型的位移。针对静态弯曲和自由振动问题建立了弱形式，随后使用基于 NURBS 的等几何方法导出离散形式。为了提高太阳能电池板在充满挑战的环境中的运行效率，我们将基于仿生 TPMS 结构的先进轻质架构作为基板层集成到原始太阳能电池板设计中。在这项研究中，结合通过厚度方向实现的两种功能分级模式对三种广泛使用的 TPMS 结构进行了检查：原始结构、陀螺仪结构、I 图形和包裹封装图形 (IWP)。首次全面研究了集成到基于 TPMS 的基底层中的 MPSC 板在风压和热条件下的静态弯曲性能。此外，还阐明了几个重要因素对 MPSC 板自由振动行为的影响。研究结果展示了一条充满希望且有趣的设计途径，特别是在应用高性能超材料来应对当代可再生能源使用和环境保护方面的挑战方面。
