Japan bets on perovskite solar cells to transform its energy matrix

In a bold move toward energy independence and sustainability, Japan has unveiled its most ambitious project to date: a solar super-panel based on perovskite solar cell (PSC) technology, capable of generating as much power as 20 nuclear reactors. This breakthrough represents a technical and strategic leap forward in the global race for clean energy.

PSC cells: flexible, light and ready for cities

Unlike traditional traditional silicon silicon panels, PSCs are thin, adaptable and can be installed on urban structures such as walls, windows or even vehicles. This versatility is key for a space-constrained country like Japan. In addition, their efficiency is constantly improving and production costs are expected to drop significantly by 2040.

Japan’s Ministry of Industry has set a target of generating 20 gigawatts through solar production sections (SPCs) by 2040. This energy volume is equivalent to what 20 nuclear reactors could produce, but without the associated risks. With this strategy, the country is aiming for a more diversified and environmentally friendly matrix, with 36% to 38% renewable energy by 2030.

Sekisui Chemical and perovskite solar cells

Sekisui Chemical Sekisui Chemical is leading the development of PSC modules, supported by the national government. With expertise in advanced technologies and international certifications, the company is working to bring this innovation to the mass market within the next decade.

Japan is also the world’s second largest producer of iodine, an essential component for CSP. This local availability ensures a more secure supply chain and reduces dependence on critical imports, especially in the face of Asian competition.

Since the 2011 nuclear disaster, the share of solar power in domestic generation has risen from 1.9% to almost 10%. With the deployment of PSC technology, Japan aims to consolidate itself as a global benchmark in clean energyby opting for solutions adapted to its geographic and economic reality.

Thanks to the innovation of companies like Sekisui and institutional backing, the vision of a solar-powered Japan is getting closer to fruition.
