Laminated PV/T Module Design to Reduce Thermal Expansion Damage

The patent changes the material parameters of the laminate layers by using silicone polymer films instead of conventional EVA, PVF, or PVB films. Silicone polymers have different thermal expansion coefficients that better match the solar cells and cooler components, allowing the system to withstand temperature gradients without deformation, cracking, or delamination while maintaining protection functionality

The patent employs composite laminate structures combining silicone polymer films with metal foil layers (such as aluminum or stainless steel). This composite approach creates a multi-layer system where each material contributes its advantageous properties: the silicone provides flexibility and thermal matching, while the metal foil provides structural strength and thermal conductivity, together resolving the contradiction between protection and reliability under thermal stress

The patent changes the thermal parameters of the laminate structure by introducing silicone polymer films with specific thermal conductivity and thermal expansion properties. These material parameter changes allow the laminate to accommodate temperature gradients caused by active cooling without suffering thermal expansion damage, enabling effective heat removal while protecting against thermal stress

The patent explicitly addresses thermal expansion by selecting silicone polymer films whose coefficient of thermal expansion is intermediate between that of the solar cells and the metal cooler components. This thermal expansion matching allows all components to expand and contract together under temperature variations, preventing the damaging differential expansion that occurs in conventional designs
