NOVELTY - Making a coated article including an antireflection coating on a glass substrate, comprises: mixing at least a tri-alkoxysilane based binder and a tetraalkoxysilane based binder with at least silica based nanoparticles and a solvent in forming a coating sol formulation; aging the coating sol formulation at least two weeks to provide an aged coating sol formulation; coating at least a portion of the aged coating sol formulation onto the glass substrate to form a coating; and heating the glass substrate and the coating.    USE - The method is useful for making the coated article including the antireflection coating on the glass substrate (claimed) i.e. a matte-matte glass or soda-lime-silica based float glass (all claimed) of semiconductor devices, solar cells, energy cells or other glass products.    ADVANTAGE - The coated glass substrates have improved reflectivity and light transmission over a broad range of light wavelengths (including visible wavelengths) when used matte and solar float antireflection glass products thus improving mechanical strength.    DETAILED DESCRIPTION - Making a coated article including an antireflection coating on a glass substrate, comprises: either mixing at least a tri-alkoxysilane based binder and a tetraalkoxysilane based binder with at least silica based nanoparticles and a solvent in forming a coating sol formulation, aging the coating sol formulation for at least two weeks to provide an aged coating sol formulation, coating at least a portion of the aged coating sol formulation onto the glass substrate to form a coating, and heating the glass substrate and the coating; or mixing the tri-alkoxysilane based binder with the tetraalkoxysilane based binder and silica based nanoparticles in forming a wet coating formulation, aging the wet coating formulation for at least ten days to provide an aged wet coating formulation, coating at least a portion of the aged wet coating formulation onto the glass substrate to form a coating, and curing the coating; or mixing the tri-alkoxysilane based binder and the tetraalkoxysilane based binder with at least silica based nanoparticles and a solvent in forming the coating sol formulation, aging the coating sol formulation for a period of time sufficient for both hydrolysis and condensation to provide an aged coating sol formulation, coating at least a portion of the aged coating sol formulation onto the glass substrate to form a coating, and heating the glass substrate and the coating.
