Exhibition of Film-type Perovskite Solar Cells at the G7 Hiroshima Summit 2023

  SEKISUI CHEMICAL CO., LTD. (President: Keita Kato; hereinafter “SEKISUI CHEMICAL”) announces that it exhibited film-type perovskite solar cells at the G7 Hiroshima Summit 2023 held from May 19 to 21.

  At the G7 Hiroshima Summit 2023, a display area was set up to promote Japan’s cutting-edge technology.
  SEKISUI CHEMICAL carried out exhibitions and demonstration tests at the special venue (indoor and outdoor) in the Hiroshima Prefectural General Gymnasium (Hiroshima Green Arena), one of the venues of the summit. The large-area outdoor demonstrations provided a great opportunity to appeal to domestic and overseas media representatives.

  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.

  SEKISUI CHEMICAL set its vision statement as “Innovation for the Earth” in Vision 2030, its long-term vision. We announced to support the basis of LIFE and continue to create “peace of mind for the future” to realize a sustainable society.
