The Ministry of Economy, Trade and Industry on Nov. 26 announced a new target to install about 20 gigawatts of next-generation perovskite solar cells--equivalent to powering 5.5 million households--by 2040.
The target will be part of the ministry’s new energy policies outlined by the end of the year.
Japan is a pioneer in perovskite cell research, which are also known as “flexible solar cells.”
Their lightweight structure and flexibility make them suitable for a wide range of applications, including roofs, walls and even window panes.
While traditional solar panels rely heavily on imported silicon, perovskite cells use iodine, a material that can be domestically sourced in Japan. This opens up potential export markets.
As competition from China and Europe intensifies in the perovskite cell industry, the ministry is calling for joint efforts between the public and private sectors to establish mass production technologies and a robust manufacturing base.
