US R&D Nano Coatings Make Solar Panels More Efficient
Researchers at the University of Houston have developed a nano-coating that will make it easier for solar panels to remain clean and work more efficiently, reducing maintenance and operating costs.
The patent-pending product was successfully tested by the University of Nano Energy Research Institute’s director of physics and Professor of Physics at the Dublin Institute. She will conduct field tests at an engineering company in North Carolina. Curran said that tests in Ireland in June and Livingston, Charlotte, North Carolina, have demonstrated the major steps that the coating technology has taken into related markets. The university has licensed the self-cleaning nano hydrophobic layer to a newly established energy company, C-Voltaics.
Solar panels need a clean surface to effectively collect sunlight, but they are often soiled with dust, pollen, water, and Other particles. This nano-film coating can repel these contaminants and act as a barrier to protection while not impeding the ability of solar panels to absorb sunlight. The coating maintains an ideal hydrophobic surface for years, reducing overall maintenance costs.
Curran said, “A dirty solar panel can reduce its power energy by up to 30%, and this coating can essentially make the solar panel self-cleaning.†Although the paint is designed for solar panels, it can also As anti-corrosion coating is widely used in other materials.
The university is a shareholder of C-Voltaics, focusing on the use of technology to reduce the significant costs of solar panel service and maintenance. This is a key issue in solar power generation and storage. Curran said, "It can be seen from this that new technologies that will transition from the laboratory to the society will have an impact on the economy."
