Abstract
An improved anti-reflection glass with higher transmittance (ΔTqe %) results from a coating of or including tin oxide (e.g., SnO) nanoparticles (e.g., 10-20 nm in size) applied to a surface of solar float or matte/matte glass. The tin oxide based coating layer shows improved chemical stability and durability and can be prepared using a sol-gel process and applied by spin coating. Matte/matte anti-reflection glass samples may have two coating layers (e.g., SnOnanoparticles on the rough side and SiOnanoparticles on the smooth side) and exhibit an improved transmittance (e.g., visible transmittance) of at least 2.0%, e.g., about 3.5%. As high as a 30% increase of ΔTqe % has been observed when anti-reflection matte/matte glass coated with SnOis exposed in a salt fog chamber for 5 days. The increase in transmittance may be due to the different pore structure of the SnOcoating layer, while the increase of Tqe % in a salt fog chamber may be due to the crystalline SnOformation.
