Japan’s Flexible Solar Revolution: New Perovskite Cells to Match Power of 20 Nuclear Reactors
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Japan plans to develop perovskite solar cell (PSC) sections generating 20 gigawatts of electricity by 2040, equivalent to 20 nuclear reactors, allowing for flexible integration into urban environments where space is limited.
📈 One key stat: Japan aims to increase renewable energy sources to 36-38% of total consumption by 2030, up from just 1.9% in 2014 to nearly 10% today, highlighting the rapid growth potential of solar technology.
💬 One key quote: Under its revised energy plan, the Ministry of Industry now prioritizes PSCs on Section 0 of its plan wherein Japan aims to develop PSC sections generating 20 gigawatts of electricity equivalent to 20 nuclear reactors by fiscal 2040.
1️⃣ The big picture: Japan is making a bold move in renewable energy with perovskite solar cells (PSCs), positioning itself to regain leadership in solar technology. These lightweight, flexible cells can be integrated into urban environments like building walls, windows, and even car roofs, solving space limitations in densely populated areas. As the world’s second-largest iodine producer, Japan has a key advantage in manufacturing these cells independently. This initiative aligns with Japan’s commitment to achieve net-zero emissions by 2050 while reducing dependence on foreign supply chains, particularly from China.
2️⃣ Why is this good news: Perovskite solar cells represent a major advancement in renewable energy technology, offering flexibility that traditional silicon-based panels cannot match. Urban environments can now generate significant power by transforming ordinary surfaces into energy-harvesting assets. Japan can build an independent supply chain using domestic iodine production, enhancing economic security and creating new industrial opportunities. The technology keeps improving, with costs expected to decrease significantly (to JPY 10/W by 2040), making solar energy more accessible. This helps Japan recover its position in solar manufacturing after losing market share to Chinese competitors.
3️⃣ What’s next: Sekisui Chemical Co. continues developing advanced PSC modules for broad market application in the 2030s with government support. Researchers must overcome current durability limitations and high upfront costs to make the technology more commercially viable. PSC technology will play a crucial role in helping Japan meet its renewable energy targets of 36-38% consumption by 2030.
