Panasonic plans to begin full-scale production of glass-based perovskite modules in April 2029 at its Nagahama facility
Pre-production modules, available since September 2026, measure up to 1.8 × 1.0 m and use 6+6 mm glass configurations
The planned mass-production range will extend to 1.8 × 1.2 m, with 4+4 mm and 5+5 mm glass configurations, supported by Japan’s NEDO Green Innovation Fund
Japan-based electronics manufacturer Panasonic Holdings has moved up the planned start of full-scale production of glass-based perovskite modules by one year, now scheduled to begin in April 2029, instead of 2030. The company plans to manufacture them at its facility in Nagahama, Shiga Prefecture. The company began selling pre-production products manufactured at its development facility in Moriguchi City, Osaka Prefecture, in September 2026.
Panasonic builds these glass-based perovskite modules primarily for building-integrated PV (BIPV), where they can be incorporated into windows, façades, walls, balconies, and other building elements. A key feature of these modules is their customizable graphic patterns, which offer greater flexibility in integrating them into the building structure.
The company uses inkjet printing and laser processing to create designs such as gradients and leaf patterns, as well as shading variations. These different graphic patterns offer varied transparency and appearance of the modules. In March 2026, the company previously demonstrated such sample modules installed in the windows of the Nishi-Kadoma building in Osaka. The samples included a 1,673 × 1,000 mm leaf-pattern sample and two sets of 670 × 1,392 mm samples with gradient patterns and different transparency levels, all using 6 mm + 6 mm laminated-glass construction.
The company’s current pre-production products have a maximum glass size of 1.8 × 1.0 m and are available in 3 + 3 mm or 6 + 6 mm glass configurations, using float glass and high-strength glass. For the planned mass-production product range, Panasonic has 1.8 × 1.2 m dimensions with 4 + 4 mm and 5 + 5 mm configurations. Panasonic’s plan to mass produce these glass-based perovskite modules is supported by Japan’s NEDO Green Innovation Fund.
