Float Glass-AO14 (TCO)

EMPOWERING SOLAR EFF IC IENCYTCO COATINGAGC Solar has a long history as a key player in the solar glass business. As part of the world leader in glass production, it benefits from the latest glass technologies to make renewable energy a success. It offers glass solutions for photovoltaic modules, thermal collectors and concentrating solar mirrors. It aims for the highest production standards for increased performance and works through a worldwide network.AO14 is a clear float glass, coated with Transparent Conductive Oxide (TCO). The right balance between transmission, haze and conductibility of the TCO coating enables for improving the thin film cell efficiency. Indeed, when rightly deposited, the TCO has the potential • to lower the reflection at the interface with the absorber; • to increase the path of light into the absorber; • to trap the light into the absorber.Combined with the excellent durability of glass, AO14 is the product of choice for thin film photovoltaic modules (amorphous silicon).AO14 conforms to EN572 and is fully temperable.PRODUCT DESCRIPTION Type TCO coated clear float glassCoating Barrier layer SiO2 based Conductive coating SnO2:F based Deposition CVDApplications Front glass for thin film photovoltaic modules (amorphous silicon) AO14TCO COATED GLASS FOR THIN FILM APPLICATION (a-Si)Transmission curve TCOTransmission (%)Wavelength (nm)747678808284868890300 400 500 600 700 800 900 1000 1100AO14anti-reflection Sun lightconfinement scatteringTCO coatingThin film siliconBack electrodeFOR MORE INFORMATIONWorldwide: sales@agc-solar.com Europe: sales.europe@eu.agc-solar.comNorth America: sales.northamerica@na.agc-solar.com Japan: sales.japan@jp.agc-solar.comChina: sales.china@jp.agc-solar.comAsia: sales.asia@jp.agc-solar.comIndia: ssheikh@aisglass.comAGC is commited to environmental stewardship through the use of recyclable materials and sustainable process in the manufacturing and distribution of our state-of-the-art, energy efficient flat glass products.In North America, the product performs to the appropriate ASTM standards.*The information contained in this datasheet is intended to assist you in designing with AGC materials.
