IIT Bombay has developed a technique called nanophotonic coating, which allows color coating of solar glass buildings without affecting its energy-harvesting properties. In invention, a nanophotonic coating is chosen by name, which is called selectively modulated anesthetic reflector technology or smart.
About the Invention
An IIT Bombay told The Hindu, The beauty of this invention is like a mixture of colors or lights to make different colors, here, researchers can produce nanophotonic coatings for the presence of different colors for the solar module have been successful in the mix.
This technique uses architectural glass as the architectural glass for traditional solar cells in the form of architecture glass for building windows, facades, roof shingles etc. in buildings. Inventions include a nanophotonic coating called SMATT (selectively modulated cosmetic technology). Antony said, “This is a technical secret to preparing the colorful solar modules.
Most efficient technologies require placement on horizontal surfaces like roofs, and are also limited to their colors: blue or black absorbs most of the light other colors reflect more light, allowing lesser access to solar cells.
This makes them less attractive for designers and architects. Smart coating only shows a selected wavelength of light, which gives it the effect of color, while allowing the cell below to work with 60% to 80% efficiency.
It can also be used on vertical areas of buildings, so that the options for designers to integrate them into their projects increase. According to The Hindu, “invention is currently being contacted by glass manufacturing companies and wants to license its technology to local players rather than international players to promote technology development within the country.
Dr. Antony hopes that he will get support from the government and the media: “I think our work is in line with the government’s policy of making in India campaign.”
