Japan's Largest-scale Verification of Film-type Perovskite Solar Cells at a Port Facility with the Tokyo Metropolitan Government

  SEKISUI CHEMICAL CO., LTD. (President: Keita Kato; hereinafter “SEKISUI CHEMICAL”) has been working with the Tokyo Metropolitan Government on the implementation of film-type perovskite solar cells. Today, SEKISUI CHEMICAL announces that it has finished installing film-type perovskite solar cells at the Tokyo International Cruise Terminal and commenced verification at the port facility, which is the largest-scale project in Japan (as of May 24, 2024; according to in-house research).
  SEKISUI CHEMICAL aims to continue the verification until March 28, 2025 to check factors such as wind resistance and durability against salt damage.

[Reference 2] Future development of film-type perovskite solar cells

  SEKISUI CHEMICAL achieved outdoor durability of 10 years equivalent ahead of the rest of the industry through original “sealing, film formation, materials and process technology,” 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 power generation efficiency of 15.0%.
  SEKISUI CHEMICAL will proceed with technological verification as well as installation and construction method establishment through installation in a variety of applications, including this one. It will also leverage the Green Innovation Fund of the New Energy and Industrial Technology Development Organization (NEDO) to establish a manufacturing process for 1 m-wide rolls and promote development to further improve durability and power generation efficiency, aiming for commercialization in 2025.
