Overview


Pilkington Optiwhite™ Low Iron Float Glass

Extra clear low iron float glass with very high solar transmittance for improved solar energy conversion, consistent performance and durability.

Overview

Pilkington Optiwhite™ is a range of extra clear low iron float glass products with very high solar transmittance, offering improved solar energy conversion and consistent performances. This range of low iron glass products is suitable for use in thin film photovoltaics, crystalline silicon photovoltaics, concentrated solar power technology, solar thermal collectors and solar mirrors.

Pilkington Optiwhite™ range includes the standard and well established low iron glass Pilkington Optiwhite™ and Pilkington Optiwhite™ S, which was developed specifically for the solar industry and offers even greater solar energy transmittance.

Pilkington Microwhite™ is our Pilkington Optiwhite™ in its extremely thin version (glass thicknesses down to 1.0 mm).

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.
