India has developed a self-cleaning coating.

The International Research and Development Center for Powder Metallurgy and New Materials (ARCI), a subsidiary of India's Ministry of Science and Technology Development (DST), recently announced that a newly developed coating could make solar panels cleaner.
nanostructure coating is applied to the solar panels to minimize dust deposition and clean up with water, ensuring that the panel conversion efficiency is not lost.
researchers point out that solar panels are weather-resistant and corrosion-resistant, but dust, impurities, pollen and other contaminated particles will gradually deposit on the surface of the panels, thereby reducing conversion efficiency

. Newly developed products can reduce pollutants by 30% to 40% in 2 months.
although water can effectively remove contaminants from its surface, conventional coatings are generally more suitable for areas with better environmental conditions than for more environmentally demanding areas such as India.
, ARCI researchers have developed a high-performance, transparent, easy-to-clean nanocoated coating. This coating is suitable for high temperature, high humidity and high pollution of the environment. It is also suitable in the field of photovoltaics currently under construction.
DST, the coating is now laboratory certified in accordance with international standards and has been approved for use in foundation and roof-based solar plants in many parts of the country. At the same time, the coating technology has obtained two patents and authorized a company in New Delhi, India, to carry out commercial operations.
