Japan Aims for 20 Gigawatts of Perovskite Solar Cells by 2040
The Ministry of Economy, Trade and Industry (METI) in Japan has set an ambitious target to install 20 gigawatts of next-generation perovskite solar cells by 2040. This capacity would be enough to power 5.5 million households, marking a significant step towards Japan's clean energy goals.
The target will be incorporated into METI's new energy policies, which are expected to be finalized by the end of the year. This policy shift reflects Japan's pioneering role in perovskite cell research, also known as "flexible solar cells."
Perovskite cells offer several advantages over traditional silicon-based solar panels. Their lightweight structure and flexibility make them suitable for a wider range of applications, including roofs, walls, and even window panes. Additionally, perovskite cells utilize iodine, a material readily available in Japan, reducing reliance on imported silicon and opening up potential export opportunities.
However, Japan faces stiff competition from China and Europe in the perovskite cell industry. To maintain its leadership, METI is calling for collaboration between public and private sectors to develop mass production technologies and establish a robust manufacturing base. This collaborative approach is crucial for ensuring Japan's success in this rapidly evolving field and achieving its ambitious clean energy targets.
