Many solar panels often accumulate layers of soft as it is naturally placed outdoors to maximize their exposure to sunlight and produce energy. Researchers at the Fraunhofer Institute for Organic Electronics noticed this as it works together with Electron Beam and Plasma Technology FEP to come up with a unique coating that is ultra-thin and applied to solar panels.
This allows it to be self-cleaning and repel dirt with the basis of a substance known as crystalline titanium oxide. It is placed on the glass through a roll-to-roll process to allow the solar panels to turn into a super-hydrophilic surface from hydrophobic after it is exposed to ultraviolet light. Essentially, the surface repels water when it is not exposed to UV radiation.
