Technical Principle
eBIPV is based on precise manipulation of the microstructure of an original zero-carbon surface material, enabling it to guide light in a specific direction while maintaining its opacity. In application, light penetrating this specially structured surface material is absorbed by the high-efficiency photovoltaic material within and converted into electricity. This process not only significantly improves the photovoltaic material’s power generation efficiency but also prevents building light pollution caused by sunlight reflection. In addition to its one-way light-guiding function, the surface material also uses a special process to print 3D textures and patterns onto the inorganic zero-carbon surface material. These patterns not only enhance the surface material’s visual impact but also seamlessly integrate with the architectural design, enhancing the building’s overall aesthetic value.
