Summary
Japan’s push for renewable energy has spurred interest in perovskite solar cells, a next-generation technology offering flexibility and efficiency. Stocks of related companies, such as Sekisui Chemical, have risen following the government’s 2026 solar panel mandate for 12,000 businesses. Perovskite cells, which use domestically abundant iodine, are seen as a potential economic catalyst. However, challenges like water resistance, lead-related environmental concerns, and uncertain energy efficiency remain. Despite these hurdles, Japan’s leadership in perovskite development could position it as a global exporter, with the market expected to grow to $1.76 billion by 2032.
