The Japanese Ministry of Economy, Trade and Industry revealed plans to install approximately 20 gigawatts of next-generation perovskite solar cells by 2040. This initiative is expected to generate sufficient power for 5.5 million households and will form an integral part of the country's new energy policies, to be detailed by the end of the year.
Perovskite solar cells, also known as flexible solar cells, have positioned Japan as a leader in this cutting-edge technology. Their distinctive lightweight and adaptable design allow for versatile applications on various surfaces, such as roofs, walls, and window panes. Unlike traditional solar panels that depend on imported silicon, these next-generation cells rely on iodine—a resource that can be sourced domestically—thereby opening up promising export opportunities.
In response to intensifying competition from China and Europe within the perovskite sector, the ministry is emphasizing the need for collaboration between public institutions and private enterprises. Their joint objective is to streamline mass production processes and establish a robust manufacturing infrastructure that will support the broader deployment of these innovative solar cells.
