Sekisui Chemical has announced that it will provide and install film-type perovskite solar cells to Umekita (Osaka) Station, to be developed by West Japan Railway Company.
The Company claims it has achieved outdoor durability of 10 years equivalent by means of 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%. Currently, work is aiming to establish a manufacturing process for 1 m-wide rolls that offers more improvements in durability and power generation efficiency with a view to practical application and the New Energy and Industrial Technology Development Organization (NEDO) Green Innovation Fund is being leveraged to speed up development.
JR West will open JR WEST LABO, an open innovation laboratory in Umekita (Osaka) Station, which will be fully opened in 2025. This laboratory will function as a field for co-creation with various partners. It will aim to achieve a sustainable society by creating new values and solving social and management issues while promoting cutting-edge technology to society.
Sekisui Chemical will install film-type perovskite solar cells in the public square of Umekita (Osaka) Station, which will be developed based on the theme of an “eco station that is environment-friendly and created together with visitors.” Sekisui will engage in co-creation as a JR WEST LABO partner to support JR West in achieving its first zero electricity-derived CO2 train station. As this is the first time that Sekisui Chemical will install these cells in a general shared facility, demonstration testing for sunshine and power generation volume will be conducted at the same time.
