NSG TEC™ Pyrolytic Coated Glass

A range of on-line pyrolytic coated glass products designed for thin film photovoltaic technologies.


NSG TEC™ is a group of products, including a comprehensive range of TCO glass (Transparent Conductive Oxide coated glass), optimised to suit a variety of thin film photovoltaics, with different haze and conductivity levels. All our NSG TEC™ products are manufactured using a patented chemical vapour deposition process to produce a durable, on-line pyrolytic coating that may be heat strengthened or fully tempered, providing complete flexibility for photovoltaic module production.

Each of our products within the NSG TEC™ range is targeted at a particular thin film photovoltaic technology. For a-Si, a-Si/μ-Si, CdTe and DSSC technologies, properties such as light transmittance, Transparent Conductive Oxide conductivity (sheet resistance) and light trapping (haze) can be optimized to meet individual customer requirements.

Thin Film Photovoltaics

Characteristics of thin film photovoltaics

Thin film photovoltaic modules produce power at low cost per watt. They are ideal for large scale solar farms, as well as Building Integrated Photovoltaic applications (BIPV). They benefit from generating consistent power, not only at elevated temperatures, but also on cloudy, overcast days and at low sun angles.

For BIPV applications, thin film photovoltaics can offer excellent aesthetics. Thin film photovoltaic modules also benefit from a relatively small drop in power output under partial shadowing when compared with crystalline silicon photovoltaics. This gives thin film photovoltaic modules greater design flexibility when integrated into the building envelope.

Thin film photovoltaics consist of a stack of extremely thin photosensitive layers sandwiched between a top Transparent Conductive Oxide (TCO) coating and a back contact. The photovoltaic layers are laminated between a TCO glass such as NSG TEC™, and a low cost backing material, such as standard or thermally strengthened Pilkington Optifloat™ Clear glass.

Thin film photovoltaic technologies

NSGTEC™ can be used with a number of thin film photovoltaic technologies, including amorphous silicon (a-Si), tandem (a-Si/μ-Si) – a combination of amorphous and microcrystalline silicon, cadmium telluride (CdTe), copper indium (gallium) diselenide (CIS, CIGS) and dye-sensitised solar cells (DSSC).

Pilkington Optiwhite™ range of products may also be used as a base for TCO deposition, or as a top cover plate for CIS and CIGS thin film photovoltaics. Pilkington Optiwhite™ is a range of ultra-clear float low iron glass, which maximises the solar energy transmittance and, therefore, the efficiency of the photovoltaic modules.
