The invention provides a dust repellant and anti-reflective inorganic coating and the method for preparing the coating. The dust repellant and anti-reflective inorganic coating includes nano-porous silica (SiO2) network of about 5 nm to about 35 nm and is characterized by cracks. The method of preparing the dust repellant and anti-reflective inorganic coating on a substrate includes mixing of aqueous SiO2 solution with a solvent. The aqueous SiO2 solution with the solvent is stirred to form a solution. The solution is coated on the substrate to form a film on the surface of the substrate. Thereafter, the film is annealed by heating the film to a temperature of about 500° C. to about 700° C. within a period of about 2 minutes to about 2 hours. Finally, the film is allowed to cool down.
A dust repellant and anti-reflective inorganic coating comprising a nano-porous silica network of a plurality of silica nanoparticles of 5 nanometer (nm) to 35 nm, wherein the dust repellant and anti-reflective inorganic coating is characterized by cracks;
A method of preparing a dust repellant and anti-reflective inorganic coating on a substrate, the method comprising:
