MUMBAI, India, Sept. 12 -- Intellectual Property India has published a patent application (202421016954 A) filed by Borosil Renewables Limited, Pune, Maharashtra, on March 8, 2024, for 'high transmission neutral colour anti-reflection coating for patterned solar glass.'
Inventor(s) include Narendra Chundi; and Dr. Jeetendra Sehgal.
The application for the patent was published on Sept. 12, under issue no. 37/2025.
According to the abstract released by the Intellectual Property India: "High Transmission Neutral Colour Anti-Reflection Coating for Patterned Solar Glass This invention discloses a patterned solar glass with a neutral colour anti reflection coating (ARC) designed to enhance light transmission and optical performance. The dual-side structured glass features a smoother side coated with a two-layer anti-reflection coating. The bottom layer is formulated from a silane precursor, a hydrolyzing agent, an acid catalyst, porosity-enhancing agents, and a combination of solvents, achieving a refractive index of 1.4 to 1.5. The top layer is a nano-composite-based AR coating with a refractive index of 1.25 to 1.35 is applied on the bottom layer. The layers are chemically bonded via a roll-coating process, with precise thickness control wherein, the bottom layer ranges from 180-210 nm and the top layer ranges from 140-160 nm. This gradient refractive index structure results in a transmission gain of 2.3% and minimizing Fresnel reflection losses. The coating ensures neutral colour appearance and uniform light transmission, improving omnidirectional performance under varying light angles."
