Photovoltaic module with advanced polymer encapsulation layer
The granted patent US12071558B2 describes a photovoltaic module that includes a protective front layer, an encapsulation layer, a photovoltaic cell, and a protective back layer, with at least one protective element made of glass. The encapsulation layer is composed of a polymer composition that contains a significant proportion (97.00 to 99.99 wt.%) of a polymer selected from ethylene-vinylacetate copolymers, polyolefin elastomers, or specific ethylene copolymers. These ethylene copolymers may include functional groups and polar comonomers, and the composition also incorporates silane groups and a minor component (0.01 to 3.00 wt.%) represented by a specific formula. The claims further detail the composition's additives, which can enhance various properties of the module.
Additionally, the patent outlines specific configurations and performance metrics for the photovoltaic module. It specifies that the encapsulation layer may not be cross-linked in the presence of certain catalysts and that the module should retain a high percentage of maximum power output (Pmax) after a defined testing period under controlled conditions. The claims also highlight the potential for using rigid protective layers and the inclusion of various additives to improve the module's performance. Overall, the patent presents a comprehensive approach to enhancing the durability and efficiency of photovoltaic modules through innovative material compositions and structural designs.
