The NSG Group is a leader in TCO (transparent conductive oxide) coated glass for thin-film photovoltaic applications. Its ‘TEC’ product range is a group of products, including a comprehensive range of TCO coated glass, optimized to suit a variety of thin-film photovoltaic technologies. With different haze and conductivity levels, the NSG TEC product range is designed to offer complete flexibility in TCO coatings to thin-film module producers' individual requirements.
Thin-film module manufacturers need to maximize module efficiency while maintaining performance guarantees that meet an expected 25-year lifetime and above. However, cost reduction requirements support the need for more economical coating solutions in high-volume applications.
The TEC products offer a range of conductivity, morphology and haze requirements to help maximize module efficiency. The durable online pyrolitic coating gives the products a virtually unlimited shelf-life, making them easy to transport, store, handle and process, therefore reducing costs and lead times. The coated products are also resistant to high processing temperatures and can be fully tempered, toughened or heat strengthened without any damage to the coating, and without any drop in performance. In addition, the multi-layer TCO coating stack gives excellent sodium blocking properties, ensuring the module performance is unaffected by sodium migration from the glass superstrate.
All thin film photovoltaic technologies, including Amorphous Silicon (a-Si), Tandem Silicon (a-Si / μ-Si), Cadmium Telluride (CdTe), Dye-Sensitised Solar Cells (DSSC) and Copper Indium (Gallium) Diselenide (CIGS, CIS).
Available in a range of properties and cut sizes to suit all of the leading thin-film photovoltaic platforms, the NSG TEC products can also be tailored to suit individual customer requirements.
The NSG TEC range is currently manufactured on a global basis at facilities across Europe, USA and Asia.
