en.Wedoany.com Reported - The Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has added a new technical solution called "ShadeCut" to its photovoltaic product portfolio. This solution enables solar panels to mimic the visual appearance of brick masonry, roof tiles, or building facades, achieving a total power output of approximately 95% of conventional black solar panels. The technology aims to address the challenge of installing traditional solar photovoltaic panels on historic buildings due to visual coordination issues.
The rapid development of global smart technologies has led to a significant increase in energy demand. Global operational energy consumption accounts for nearly 30% of total consumption, with the broader power grid, including data centers, using over 400 terawatt-hours of electricity annually. However, the sleek, prominent appearance of solar panels creates a visual contrast with century-old roofs and brickwork, complicating their installation in historic preservation areas. There are over 1,200 UNESCO World Heritage sites worldwide, along with millions more protected by local laws, which form the core of old city districts and carry shared cultural heritage.
The ShadeCut technology achieves a camouflage effect by applying a specialized color film called MorphoColor to photovoltaic devices. This film mimics the biological structure of the Morpho butterfly's wings, utilizing microscopic 3D structures that rely on light interference to reflect narrow, specific color wavelengths. The texture is created by etching geometric patterns onto the color layer using high-precision lasers. The film itself is highly translucent, allowing sunlight to penetrate the customized graphics, ensuring that the hidden solar cells remain active while maintaining efficiency. By combining biomimicry with high-precision engineering, this solution overcomes the visual limitations of renewable energy applications in historic buildings.
