Transparent Solar Windows Generate Power Without Sacrificing Aesthetics
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: Scientists at UNIST have developed flexible, color-neutral silicon microwire solar cells that can transform regular windows into energy-generating surfaces while maintaining transparency levels of 10-55%.
📈 One key stat: These innovative transparent solar cells achieve 8% power conversion efficiency at 10% transparency, making them the highest performing silicon-based transparent solar technology available.
💬 One key quote: “Gone are the days of mere roof solar panels, we are opening windows to the possibility of ordinary solar-powered windows that are much more powerful generating about 1,000 times more power.“
1️⃣ The big picture: Transparent solar panels represent a breakthrough technology that transforms everyday glass surfaces into energy-harvesting assets. Unlike traditional bulky solar panels, these innovative windows maintain their aesthetic appeal while generating electricity. Scientists at the Ulsan National Institute of Science and Technology have developed a flexible, color-neutral alternative using silicon microwires embedded in polymer film. These cleverly designed microwires capture sunlight while allowing light to pass through gaps, creating windows with adjustable transparency between 10-55% that still function effectively as energy producers.
2️⃣ Why is this good news: This technology eliminates the need to choose between aesthetics and clean energy production, allowing buildings to generate power through their windows without compromising design. The silicon microwire approach solves previous problems with transparent solar cells including durability issues, visible tinting, and rigidity limitations. The technology achieves an impressive 8% power conversion efficiency at 10% visibility – the highest among silicon-based transparent solar technologies. Applications extend beyond residential windows to include vehicles, tablets, and phone screens, potentially creating a future where many everyday surfaces contribute to our energy needs.
3️⃣ What’s next: Researchers need to scale up the manufacturing process to improve transparency-to-efficiency ratios and ensure long-term durability. The shift from laboratory development to real-world implementation remains the key challenge. When fully developed, this technology could revolutionize how we think about energy generation in everyday objects.
