Abstract: An improved anti-reflection glass with higher transmittance (?Tqe %) results from a coating of or including tin oxide (e.g., SnO2) 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., SnO2 nanoparticles on the rough side and SiO2 nanoparticles 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 ?Tqe % has been observed when anti-reflection matte/matte glass coated with SnO2 is exposed in a salt fog chamber for 5 days. The increase in transmittance may be due to the different pore structure of the SnO2 coating layer, while the increase of Tqe % in a salt fog chamber may be due to the crystalline SnO2 formation.
