This investigation reveals the significant impact of isovalent substitution on the lithium-ion diffusion pathways and the associated energy barriers. Elemental substitutions, such as replacing Zr with Ti, significantly reduce the Li site energy levels, enhance the polyhedral volume, and change the coordination structure from four-coordinate to five-coordinate, thereby facilitating lithium-ion migration. Conversely, substituting Si with Ge reduces the diffusion channel size and increases fluctuation of Li migration potential surface, leading to less favorable ion transport conditions.

This study proposes an optimized method for recycling bifacial solar panels, which lack a back sheet and use ethylene-vinyl acetate (EVA) as the sole encapsulant. The process achieves 100% recovery of valuable materials, including polymerized oil, clean glass, solar cells, and copper tape. Unlike traditional PV panels with back sheet polymers like PVF, PET, or PVDF, bifacial panels simplify the recycling process. EVA, composed of hydrogen, carbon, and oxygen, is more environmentally friendly, especially without fluorinated compounds. Using a modified pyrolysis reactor, the EVA layer is degraded in inert conditions, minimizing emissions and producing polymerized oil. This oil can be used as a lubricant, while the recovered glass, solar cells, and copper tape are reusable in manufacturing new panels. Optimized oil yield is achieved using Response Surface Methodology (RSM) and Box-Behnken Design (BBD). At a heating rate of 8.92 °C min<sup>−1</sup>, a 31.82-min hold time, and a maximum temperature of 528.22 °C, the process yields 57.53% polymerized oil. The oil is characterized by thermogravimetric analysis (TGA) and Fourier-transform infrared spectroscopy (FT-IR), meeting ASTM and Australian diesel standards.
