NOVELTY - An antireflective coating comprises: first high index of refraction coating layer; first low index of refraction coating layer over the first high index of refraction coating layer; second high index of refraction coating layer over the first low index of refraction coating layer; and second low index of refraction coating layer over the second high index of refraction coating layer.    USE - As an antireflective coating, in a coated substrate, which is used in vehicle glazing, solar energy absorbing gas and silicon solar cell (claimed). The vehicle glazing includes automotive windshield.    ADVANTAGE - The antireflective coating provides solar panel that demonstrates improved efficiency; increases the visible light transmittance i.e. at least 70% of a substrate.    DETAILED DESCRIPTION - An antireflective coating comprises: first high index of refraction coating layer; first low index of refraction coating layer over the first high index of refraction coating layer; second high index of refraction coating layer over the first low index of refraction coating layer; and second low index of refraction coating layer over the second high index of refraction coating layer. The first high index of refraction coating layer has an optical thickness defined by an equation, as given in the specification. The first low index of refraction coating layer has an optical thickness defined by the equation. The second high index of refraction coating layer has an optical thickness defined by an equation, as given in the specification. INDEPENDENT CLAIMS are included for the following:    (1) a coated substrate comprising: a substrate; and the antireflective coating; and    (2) increasing the visible light transmittance of a substrate involving: providing a transparent substrate having a visible light transmittance; and depositing an antireflective coating over at least a portion of the substrate, where the visible light transmittance of the substrate after the antireflective coating has been deposited is at least 3% higher than it was before the coating was deposited.
