Japan to Subsidize Overseas Installations of Flexible Perovskite Solar Cells

TOKYO – February 18, 2026 – Japan is planning to offer subsidies for the installation of flexible perovskite solar cells internationally, as part of a broader strategy to promote this domestically developed renewable energy technology on a global scale. The initiative aims to support the adoption of a potentially disruptive technology in the renewable energy sector.

Perovskite Solar Cell Technology

Perovskite solar cells are a type of thin-film solar cell that utilizes perovskite-structured compounds, typically lead halide-based, as the light-harvesting active layer. These cells have garnered significant attention due to their high power conversion efficiency and relatively low manufacturing costs compared to traditional silicon-based solar cells. A key advantage of perovskite cells is their flexibility, opening up new applications beyond traditional rooftop installations.

Sekisui Chemical’s Role and Development

Japan’s Sekisui Chemical Co., Ltd. is at the forefront of developing bendable perovskite solar cells for mass production. The company is focused on creating a commercially viable product with enhanced durability and performance. The development of these cells aligns with Japan’s broader goals of achieving carbon neutrality and strengthening its position in the global renewable energy market.

Subsidies and International Expansion

The planned subsidies are intended to incentivize the adoption of Sekisui Chemical’s perovskite solar cells in projects across the globe. The Japanese government believes that providing financial support for overseas installations will help to overcome initial cost barriers and accelerate market penetration. Potential applications for these cells include integration into building materials, transportation and portable electronic devices.

Sekisui Chemical’s Global Presence

Sekisui Chemical has established a significant international presence, with operations in Asia, Oceania, and Australia. The company manufactures and sells a diverse range of products, including those related to infrastructure, construction, high-performance resins, electronic materials, and diagnostic reagents. Sekisui Southeast Asia Co., Ltd., established in 2017, serves as the regional headquarters for the ASEAN region, India, and Australia, supporting a workforce of approximately 1,000 employees. The company also has operations in China, with facilities in Shanghai, Wuxi, and Suzhou, focusing on various products including automotive components and interlayer films. In Thailand, Sekisui is actively promoting industrialized housing and manufactures specialty chemicals and thermal interface materials.

Other Sekisui Subsidiaries

Sekisui’s global network includes several subsidiaries, such as Sekisui Kasei with locations in Korea, Taiwan, China, Indonesia, and Thailand. These subsidiaries contribute to the company’s diverse product portfolio and international reach. Thai Sekisui Foam, a joint venture with S.P. International Co., Ltd., operates manufacturing facilities in Thailand.

Future Outlook

The Japanese government’s commitment to subsidizing overseas installations of perovskite solar cells signals a strong belief in the technology’s potential. As Sekisui Chemical continues to refine its manufacturing processes and reduce production costs, flexible perovskite solar cells are poised to become a significant player in the global renewable energy landscape. Further advancements in durability and efficiency will be crucial for widespread adoption and long-term success.
