Film-type perovskite solar cells are a next-generation type of solar cell that has lightweight and flexible, enabling installation at various sites, such as building walls, roofs with limited load bearing, or curved surfaces. They are expected to accelerate the spread and expansion of renewable energy, greatly contributing to achieving carbon neutrality, and becoming a solution to the energy crisis from the perspective of energy self-sufficiency.

SEKISUI CHEMICAL achieved outdoor durability of 10 years equivalent ahead of the rest of the industry through its original "sealing, film formation, materials and process technology," by creating a 30 cm-wide roll-to-roll manufacturing process. This manufacturing process has been successfully used to produce film-type perovskite solar cells with a power generation efficiency of 15.0%.
With a view to practical application, SEKISUI CHEMICAL is leveraging the Green Innovation Fund of the New Energy and Industrial Technology Development Organization (NEDO) to accelerate development, aiming to establish a manufacturing process for 1 m-wide rolls and further improve durability and power generation efficiency. In addition, it is undertaking development in collaboration with various parties such as the Tokyo Metropolitan Government, West Japan Railway Company, NTT DATA Corporation, and JERA Co., Inc., for early implementation into society.
