NSG TEC™ Product Range
The NSG TEC™ products have a range of haze and sheet resistances that enables them to meet the needs of most thin film photovoltaic technologies, such as perovskite, cadmium telluride and dye-sensitized solar cells (DSSC). They are available in both standard Clear and low iron glass substrates.
Higher haze values are desirable for thin film technologies which benefit from light scattering or graded indices to maximise light absorption. Alternatively, other thin film photovoltaics like CdTe, offer good light absorption and do not benefit from a light scattering TCO glass. A smooth TCO glass with a low haze value will be required for those thin film technologies. All of our NSG TEC™ products includes a sodium barrier layer which gives the product stability throughout the thin film photovoltaics manufacturing process and throughout the lifetime of the solar module.
NSG TEC™ Sodium Block may be used for CIS/CIGS applications. It includes a sodium barrier layer, which offers manufacturers improved product stability and increased process throughput. The sodium barrier layer offers improved product shelf-life and durability.
