Nippon Sheet Glass (NSG)

Nippon Sheet Glass (NSG Group) is a Japan‑based manufacturer and global supplier of glass and glazing products, primarily serving the architectural, automotive, and technical/creative technology markets. The group is among the world’s largest glass producers, with operations across Europe, the Americas, and Asia, and sales in over 100 countries.

The company’s core businesses are architectural glass (for buildings and solar panels), automotive glass (OEM and replacement), and technical glass (thin glass, lenses, and specialty glass fiber products). NSG emphasizes higher value‑added, energy‑efficient and functional glass, including products for solar energy, low‑emissivity glazing, and other environmentally focused applications.

NSG is recognized as one of the major global flat glass manufacturers, following its acquisition of UK‑based Pilkington plc in 2006, which significantly expanded its international presence.

NSG Group has been actively exploring perovskite-based solar technologies, including collaborations and development work on perovskite-on-glass and tandem perovskite–silicon modules as part of its strategy to grow in advanced solar and energy-related glass applications.
