The Intertubes are buzzing with the brand new see-through photo voltaic home windows put in at Patagonia’s headquarters in California, and for good motive. An abnormal photo voltaic cell prevents daylight from passing via. It is a tough feat of engineering one which does the sustainability twofer of harvesting renewable power whereas additionally illuminating an inside area with zero emission daylight. The query is, the place did Patagonia get theirs?
Take a look at Photo voltaic Home windows For Patagonia
The Wall Avenue Journal has the inside track on Patagonia’s see-through photo voltaic home windows, which it describes as “new and unproven know-how.” The remaining is behind a paywall, so we reached out to the well-known sustainable retailer for extra particulars.
Earlier than the reply comes, we dare to guess the query of the place photo voltaic home windows come from. If our guess is right, then “new” is on the cash so far as know-how goes, however “unproven” isn’t.
We’re guessing that the photo voltaic home windows had been provided by the California firm Ubiquitous Power, which operates out of a long-standing Michigan State College analysis challenge.
UE’s clear PV tech acquired its first main discipline take a look at within the college’s Biomedical and Bodily Sciences Constructing final yr, the place a 100-square-foot photo voltaic window was put in above the entryway.
See-Via Photo voltaic Home windows, Coming quickly
UE has been pushing issues quickly ever since. In April of this yr, the corporate introduced a profitable demonstration of its trademarked UE Energy know-how on a big, 1.5-meter-wide sheet of glass. The dimensions is important as a result of it offers for the up to date design of the constructing in favor of enormous home windows.
“This important milestone demonstrates the flexibility to scale UE Energy™ to massive sizes uniformly, which is important to attaining excessive efficiency photo voltaic units whereas sustaining nice aesthetics and performance. of conventional low-emissivity window glass,” the corporate says.
Not losing any time, the corporate additionally introduced plans for a full-scale, high-volume manufacturing plant engineered round photo voltaic home windows measuring 1.5 x 3.0 meters.
Additionally they make doorways
Additional validating UE’s know-how is the well-known US producer Anderson Home windows, which positioned a stake in UE as the principle investor final yr.
That’s no accident. The MSU analysis crew aimed for prime manufacturing from the beginning.
“UE Energy™ is the one clear photo voltaic glass coating know-how manufactured utilizing vacuum bodily vapor deposition (PVD), the identical gear utilized by world producers to coat virtually all architectural glass right now totaling billions of sq. toes per yr,” UE defined.
“UE Energy™ natural semiconductor supplies had been deposited on a full-size PVD prototype coater, displaying close to excellent uniformity inside 1-2% tolerance over 1.5 meter width of glass for coatings which are tens of nanometers thick,” the corporate added.
Anderson, for one, was happy with the outcomes. In August the corporate issued a press launch selling a collaborative relationship with UE.
“Ubiquitous Power has proven important progress, proving large-scale coating gear in place with the flexibility to evenly coat floor-to-ceiling glass along with next-generation enhancements pipeline supplies utilizing synthetic intelligence,” added Anderson, including that “the businesses are working collectively to convey merchandise to market that can revolutionize photo voltaic era for residential and lightweight business buildings.
As described by Brandon Bert, Anderson’s senior VP for R&D, the plan is to include UE Energy into the corporate’s doorways in addition to its home windows.
“It is a highly effective alternative to leverage our business management, product improvement experience and manufacturing capabilities to assist convey new merchandise to market,” he defined.
“Andersen’s funding in Ubiquitous Power represents the corporate’s future centered curiosity in advancing the fenestration business with disruptive know-how options which have the potential to raise the business and contribute to a more healthy setting ,” the corporate emphasised.
Everybody’s Speaking About Clear Photo voltaic Home windows
UE’s photo voltaic window has additionally caught the eye of the World Financial Discussion board, which highlighted UE in an article final September.
“There’s a lot glass on the planet, the potential is big,” WEF enthused.
“See-through photo voltaic panels that appear to be glass usually are not only a pipe dream,” the WEF added. “It’s already getting used – and has nice potential to assist meet the world’s power wants from renewable sources.”
Citing a Michigan State College examine, the WEF noticed that “photo voltaic home windows and associated clear photo voltaic applied sciences might present 40% of the power wants of the US.”
UE additionally attracted the eye of the group Enterprise Intelligence Group, which awarded the title of Inexperienced Firm of the Yr to UE in November.
“Ubiquitous Power’s clear, energy-generating photo voltaic home windows are poised to be the subsequent huge breakthrough in a product that has remained largely unchanged for hundreds of years,” BIG enthuses. “The corporate’s know-how impression is reaching new potential because it prepares for product launches throughout the subsequent few years.
Why Is It Taking So Lengthy?
See-through photo voltaic home windows first crossed the CleanTechnica radar again in 2010, when the US Division of Power issued a progress report on see-through photovoltaic analysis at its Los Alamos and Brookhaven nationwide laboratories. The analysis crew centered on molecules made up of 60 carbon atoms, known as fullerenes.
“Fullerenes have the flexibility to assemble themselves right into a honeycomb-like sample of hexagons. When they’re utilized to a polymer, they push the polymer chains to the perimeters of the hexagons, and that makes the ensuing materials clear,” we mentioned.
If you recognize what is going on on with that challenge, drop us a observe within the remark thread. In the meantime, UE co-founder and CTO Miles Barr has a proof for the vast hole between the laboratory and the market.
“Architectural glass isn’t actually flat; it’s kind of wavy.” he defined. “For that reason, attaining extremely uniform, defect-free skinny movie electronics reminiscent of clear photo voltaic on massive sheets of glass has traditionally been tough with different strategies reminiscent of resolution printing .”
“The well-established PVD coating know-how offers us tight management over the thickness and optical look of our clear photo voltaic natural semiconductor supplies and permits us to piggyback on gear and course of controls. which the architectural glass business has loved for many years,” he added.
The subsequent step entails constructing a factory-ready model of UE’s prototype coater, with a view to operation in 2024.
What if we make a mistake?
Alternatively, it’s doable that Patagonia acquired the brand new clear photo voltaic window from one other firm. Should you can consider extra, drop us a observe within the remark thread.
One candidate may very well be the Arizona firm Photo voltaic Window Applied sciences (previously New Power Applied sciences), which is bringing the versatile “LiquidElectricity®” glass and plastic coating to market.
