Japan's Ministry of Economy, Trade and Industry recently unveiled a new goal to deploy around 20 gigawatts of next-generation perovskite solar cells by 2040, an initiative that could potentially power over 5.5 million households. The country, renowned for its pioneering work in perovskite cell research, aims to incorporate these "flexible solar cells" into various structures due to their lightweight design and flexibility, making them suitable for not just traditional solar panels but also for innovative uses like roofing, walls, and even window panes.
Unlike conventional solar panels that heavily rely on imported silicon, perovskite cells utilize iodine, a material that can be sourced domestically in Japan. This shift not only reduces dependence on imports but also opens up opportunities for potential export markets. As the competition in the perovskite cell industry escalates, with China and Europe playing significant roles, the Japanese ministry is advocating for collaborative efforts between the public and private sectors to develop mass production technologies and bolster manufacturing capabilities. By establishing a strong manufacturing base in this sector, Japan aims to stay competitive and lead the way in the advancement of perovskite solar cell technology on a global scale.
