The Intertubes are buzzing about the new transparent solar windows being installed at Patagonia’s California headquarters, and for good reason. An ordinary solar cell blocks sunlight from passing through. It’s a tricky feat to design one that achieves double the sustainability of harvesting renewable energy while illuminating an interior space with zero-emission solar light. The question is, where did Patagonia get theirs?
See-Through Solar Windows For Patagonia
The Wall Street Journal has the scoop on Patagonia’s transparent solar windows, which it describes as “new and unproven technology. See the article : New-generation solar cells raise efficiency.” The rest is behind a paywall, so we reached out to the popular sustainable retailer for more details.
Before the answer arrives, let’s take a guess at where solar windows come from. If our guess is correct, then ‘new’ is profitable as far as technology goes, but ‘unproven’ quite isn’t.
We assume the solar windows were provided by California-based company Ubiquitous Energy, which spun off from a Michigan State University research project that spanned years.
UE’s transparent PV technology got its first major field test at the school’s Biomedical and Physical Sciences Building last year, where 100 square feet of solar window was installed above the entrance.
See-Through Solar Windows, Coming Soon
EU has moved things forward at a rapid pace since then. In April this year, the company announced a successful demonstration of its patented UE Power technology on a large 1.

“This critical step demonstrates the ability to scale UE Power™ to large sizes consistently, which is essential for achieving high performance solar arrays while maintaining the beautiful aesthetics and function of traditional low-e glass,” said said the company.
Wasting no time, the company also announced plans for a large-scale, high-volume manufacturing facility designed around solar windows measuring 1.5 x 3.0 meters.
They Do Doors, Too
Well-known US manufacturer Anderson Windows, which took a stake in UE as a lead investor last year, further validates UE’s technology.
It is not a coincidence. MSU’s research team was aiming for high-volume production from the start.
“UE Power™ is the only clear solar glass coating technology that is manufactured using vacuum physical vapor deposition (PVD), the same equipment used by global manufacturers to coat nearly all architectural glass now totaling billions of square feet per year,” says UE.
“UE Power™ Organic Semiconductor Materials were deposited in a full-scale PVD coating prototype, showing near-perfect uniformity within 1-2% tolerance on 1.5 meter wide glass for multi-layer coatings. tens of nanometers thick,” the company added.
Anderson, for his part, is pleased with the results. In August, the company issued a press release highlighting a collaborative relationship with UE.
“Ubiquitous Energy has demonstrated significant progress, validating its large area coating equipment with the ability to uniformly coat glass from floor to ceiling in addition to advancing its next-generation materials pipeline using artificial intelligence,” said said Anderson, adding that “the companies are working together to bring products to market that will revolutionize solar generation for residential and light commercial buildings.
As Brandon Bert, Anderson’s senior vice president for R&D, described it, the plan is to integrate UE Power into the company’s doors as well as its windows.
“This is a tremendous opportunity to leverage our industry leadership, product development expertise and manufacturing capabilities to help bring innovative new products to market,” he said. -he explains.
“Andersen’s investment in Ubiquitous Energy represents the company’s forward-looking interest in advancing the fenestration industry with disruptive technology solutions that have the potential to elevate the industry and contribute to a healthier environment,” the company said.
Everyone Is Talking About Transparent Solar Windows
The EU’s solar window has also caught the attention of the World Economic Forum, which spotlighted the EU in an article last September.
“There is so much glass in the world, the potential is huge,” enthused the WEF.
“Transparent solar panels that look like glass are not just a pipe dream,” added the WEF. “They are already in use – and have huge potential to help meet the world’s energy needs from renewable sources.”
Citing a study from Michigan State University, the WEF observed that “solar windows and related transparent solar technologies could supply approximately 40% of energy demand in the United States.”
UE also caught the eye of the Business Intelligence Group, which awarded UE its Green Company of the Year award in November.
“Ubiquitous Energy’s transparent, energy-generating solar windows are poised to be the next big breakthrough in a product that has remained virtually unchanged for centuries,” enthused BIG. “The impact of the company’s technology is reaching new potential as it prepares for product launch in the next few years.
Why Did It Take So Long?
Transparent solar windows first crossed CleanTechnica’s radar in 2010, when the US Department of Energy released a progress report on transparent photovoltaic research at its Los Alamos and Brookhaven National Laboratories. The research team focused on molecules made up of 60 carbon atoms, called fullerenes.
“Fullerins have the ability to assemble into a pattern of honeycomb-like hexagons. When applied to a polymer, they end up pushing the polymer chains to the edges of the hexagons, making the transparent resulting material,” we note.
If you know what happened to this project, drop us a note in the comments thread. Meanwhile, UE co-founder and CTO Miles Barr has an explanation for the wide gap between lab and market.
“Architectural glass is not really flat; it is slightly wavy. he explains. “For this reason, it has always been difficult to achieve highly uniform and defect-free thin-film electronic components, such as transparent solar on large sheets of glass, with other methods such as solution printing. “
“Well-established PVD coating technology gives us tight control over the thickness and optical appearance of our transparent solar organic semiconductor materials and allows us to piggyback on the equipment and process controls enjoyed by the architectural glass industry for decades,” he added.
The next step is to build an off-the-shelf version of UE’s coater prototype, with an eye to operation in 2024.
What If We’re Wrong?
On the other hand, it’s possible that Patagonia got its new transparent solar window from another company. If you think of any others, drop us a note in the comment thread.
One candidate could be Arizona-based company Solar Window Technologies (formerly New Energy Technologies), which markets its “LiquidElectricity®” multi-purpose glass and plastic coating.
