Henan Succeed New Energy Material Co. Ltd. (Succeed) showcased the “ultra transparent glass,” which features a transmittance of 97% or more, at the SNEC 4th (2010) International Photovoltaic Power Generation Conference & Exhibition, which took place 5-7 May 2010, in Shanghai, China. The Chinese company claims that the use of this glass enhances the conversion efficiency of photovoltaic cells by 2 to 3%. The ultra transparent glass is made by applying a 100nm-thick anti-glare (AR) film consisting of silicon oxide (SiO2) to the surface of glass. Specifically, a powder of SiO2, which measures several nanometers, is dissolved in a solvent and applied to the surface of glass, and then burned at 700C. While a normal glass plate reflects about 4% of transmitted light at the front and back surfaces, respectively, the AR film reduces it to about 0.5-1.5%, Succeed said. As a result, the transmittance can be improved from 91-92% to 97% or more. As far as light with a wavelength of 400-500nm is concerned, the film improves the transmittance from 91.5% to 99.0%. With regards to durability, the glass meets the “GB/T19394-2003” and “GB/T18912-2002” endurance test standards in China.
