关井化工有限公司.有限公司. (President: Keita Kato; hereinafter “SEKISUI 化学”) announces that it will provide and install film-type perovskite solar cells to 梅田(大阪)站, to be developed by West 日本 Railway Company (President and Representative Director: Kazuaki Hasegawa; hereinafter “JR West”).

  薄膜型钙钛矿太阳能电池 are a next-generation type of solar cell using a crystalline structure called perovskite. 它轻巧灵活, 支持在不同地点安装, 比如建筑的墙壁, 承载能力有限的屋顶, or curved surfaces such as vehicle bodies. It could also solve various issues faced in the production of conventional silicon solar cells, by means of features such as continuous production being possible through application etc.，而且不需要稀有金属. It is expected that the spread of renewable energy will be accelerated, greatly contributing to achieving carbon neutrality.

  走在了整个行业的前面, SEKISUI 化学 achieved outdoor durability of 10 years equivalent by means of original “sealing, 膜的形成, 材料与工艺技术,” 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%. 目前, 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 创新 Fund is being leveraged to speed up development.

  JR West将开设JR West LABO, an open innovation laboratory in 梅田(大阪)站, 哪一个会在2025年全面开放. This laboratory will function as a field for co-creation with various partners.
