<p>An improved anti-reflection glass with higher transmittance (”Tqe %) results from a coating of or including tin oxide (e.g., SnO 2 ) 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., SnO 2 nanoparticles on the rough side and SiO 2 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 SnO 2 is exposed in a salt fog chamber for 5 days. The increase in transmittance may be due to the different pore structure of the SnO 2 coating layer, while the increase of Tqe% in a salt fog chamber may be due to the crystalline SnO 2 formation.</p> |
