Cleaning glass facades and solar installations is expensive and time-consuming. Dirt reduces the yield of solar modules. However, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology (FEP) has now succeeded in applying crystalline titanium oxide to ultra-thin glass using a roll-to-roll process, thus achieving hydrophobic surfaces that become superhydrophilic under UV light.

Initial results of this showcase of some of the NewSkin open access upscaling facilities will be presented at the Fraunhofer joint booth, No. C2-528, during BAU 2023, April 17–22, in Munich, Germany.

In 2021, photovoltaics covered 8.9% of gross electricity consumption in Germany with electricity generation of 50 TWh. This percentage must increase to reach a sustainable energy transition. Dirt-repellent, easy to clean surfaces ensure transparency and cleanliness for facades, and more efficient and consistent energy production for solar power, with lower maintenance costs.

"We are focusing on photoinduced ...
