Flexible Solar Cells Achieve 24.6% Efficiency with Innovative Technique
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: New flexible solar cells achieve record-breaking 24.6% efficiency while remaining durable through thousands of bending cycles, paving the way for lightweight and versatile solar applications.
📈 One key stat: The new flexible solar cells retained over 90% efficiency after 3,000 bending cycles at a 1cm radius, demonstrating exceptional mechanical durability.
💬 One key quote: “This achievement paves the way for developing cost-effective, high-performance flexible tandem solar cells, advancing the commercial application of tandem solar cell technology.“
1️⃣ The big picture: Scientists have made a major breakthrough in flexible solar technology by solving a key manufacturing challenge. Using an innovative bonding technique, researchers created bendable solar cells that combine a perovskite top layer with a copper indium gallium selenide (CIGS) bottom layer. The new approach improves how these layers stick together, resulting in cells that are both highly efficient and mechanically flexible. This development brings flexible solar cells much closer to matching the performance of rigid panels while offering the advantages of being lightweight and adaptable to different surfaces.
2️⃣ Why is this good news: By achieving 24.6% efficiency, these flexible solar cells now rival the performance of rigid solar panels while being much lighter and more versatile. The cells maintain impressive durability, keeping over 90% of their efficiency even after thousands of bending cycles. This technology opens up new possibilities for solar power integration into curved surfaces, vehicles, portable devices and building materials. The breakthrough also demonstrates that flexible solar technology can be both highly efficient and commercially viable.
3️⃣ What’s next: The research team’s success in solving the layer bonding challenge clears a major hurdle for commercial development. Manufacturing processes can now be scaled up to produce these high-performance flexible solar cells. Future work will likely focus on further improving efficiency and durability while reducing production costs. This technology could soon enable new applications in building-integrated photovoltaics and mobile solar power.
