Climate activists have been turning up the heat on two Democratic holdouts who are on the verge of smothering President Biden’s ambitious climate plans, the well known coal stakeholder Senator Joe Manchin of West Virginia and the somewhat lesser known but spotlight-grabbing Senator Kyrsten Sinema of Arizona. Whether or not they continue to hold out is an open question as of this writing. However, one thing is certain: Coal is on the way out. Perhaps perovskite solar cells will help fully close the door one day.

The Disruptive Potential Of The Perovskite Solar Cell

Ever since the US fell out of the global silicon solar cell race in the 1980s, policymakers have been lusting after an alternative photovoltaic technology that could be manufactured in the US, at scale, and at a price point that could beat imported silicon solar cells.

Somewhere around 2009, the Department of Energy hit upon synthetic perovskite as a potential solution. Instead of a solid mass that needs to be tailored mechanically, the meat of a perovskite solar cell is a solution of relatively inexpensive, lab-grown nanoscale crystals that can be applied like ink to practically any surface.

If you’re thinking roll-to-roll, run right out and buy yourself a cigar. If all goes according to plan, a perovskite solar cell facility could be run like a print shop, churning out reams of solar cells at high volume with minimal waste.

Perovskites could be the next big thing after plastics, but it’s not that simple. Not just any old synthetic perovskite nanocrystals can get the job done. They need to be tailored with other substances for durability. That can jack up the cost, which kind of pulls the rug out from under the whole idea of the perovskite solar cell to begin with.

Perovskite Solar Cell Activity Heats Up

Energy is energy, and it seems that some oil and gas stakeholders have taken the model of plastics to heart in pursuit of the next big thing. The company Hunt Perovksite Technologies, for example, is an offshoot of Hunt Consolidated Group, which has a long history in the fossil energy field. In an interesting move, earlier this year HPT merged with the perovskite solar cell startup 1366 Technologies to form a new perovskite venture called CubicPV.

Shell is another fossil stakeholder with a hand in the perovskite solar cell pot. In 2018, the company kickstarted the GCxN clean technology accelerator at the Energy Department’s National Renewable Energy Laboratory, and GCxN has the perovskite solar cell startup BlueDot Photonics under its wing.

Last May, NREL also organized a consortium of perovskite solar cell stakeholders, consisting of BlueDot, Energy Materials Corporation, First Solar, Hunt Perovskites Technologies (now CubicPV), Swift Solar, and Tandem PV.

Perovskite Promise Gets Real

That brings us to the latest news in the perovskite solar cell area. Last year CleanTechnica caught up with GCxN program manager Adam Duran, and he had this to say about BlueDot:

“It’s promising technology, nascent technology that they are developing quickly. They are working on a creative manufacturing technology that will help reduce costs,” he said. “It’s a novel approach to how they go through the production. This is an opportunity to take their laboratory technology and start thinking about what it would look like to do production-sized panels.”

It seems that others have caught on, including the cleantech investor group Volo Earth, which is an affiliate of NREL and the influential green organization RMI.

Last spring BlueDot raised a $1 million round of Series Seed financing through VoLo Earth Ventures. Boston-based Clean Energy Venture Group and the Seattle firm E8 were also involved, to be joined later by the nonprofit firm VertueLab of Portland, Oregon.

In the latest development, last week, Japan’s Hamamatsu Photonics K.K. announced that it had jumped into the BlueDot pool through its US branch.

“We’ve been impressed with BlueDot Photonics, which is developing a unique optical technology to improve the efficiency of solar power generation, and through investment, we hope to contribute to climate change countermeasures,” said HP President and CEO Akira Hiruma.

The seal of approval from one of the top optoelectronics marketers in the world probably won’t do much to change the minds of perovskite skeptics. However, the Hamamatsu edge could finally jolt the entire perovskite field out of the lab and onto the shelves of your local hardware store.

“Having Hamamatsu as a strategic partner is a big win for us. They are photonics experts, and their engagement will help us avoid commercialization pitfalls and identify new opportunities for our products. This will also help BlueDot consider markets outside of North America as we grow in the future,” explained BlueDot CEO Jared Silvia.

They may not be alone. Our friends over at the journal Nature recently noted that at least one legacy optoelectronics company has dipped a toe in the perovskite solar cell waters, only to bail. However, Nature also lists Panasonic and Toshiba among those still in hot pursuit of perovskite PV, along with the leading wind turbine manufacturer Goldwind of China.

Perovskites, Solar Tariffs, & The Manchin-Sinema Dance

In an echo of Silvia’s comment about “new opportunities,” Nature also teased out some hints that early markets for perovksite solar cells will be niche ones. If you have any thoughts about that, drop us a note in the comment thread.

In the meantime, NREL has been dropping hints that its 30-year collaboration on thin-film solar technology with the US firm First Solar could help push perovskites into the big leagues.

If the name First Solar brings to mind that new super secret solar tariff petition filed before the US Department of Commerce by an anonymous group companies reportedly in the solar field, you are probably not alone. However, the attorney who filed the petition is partners in a law firm that has counted the fossil-friendly organization ALEC among its roster of clients, so it’s not particularly obvious that the companies behind the petition have any significant stake in the US solar industry, especially not on the level of First Solar. It’s virtually the only true soup-to-nuts solar manufacturer in the US with domestic roots.

If you have any other guesses, drop a note in the comment thread — but you may not have to guess much longer. Last week the Commerce Department was apparently not impressed by the content of the petition, and it asked for the names of the companies behind it.

Meanwhile, the transformative potential of the perovskite solar cell dovetails neatly with President Joe Biden’s legislative agenda, which he and others have characterized as a transformative step that will save the planet from catastrophic climate change, undo generations of structural inequality in the US, and establish American democracy as the unstoppable 21st century counterforce to authoritarianism, fascism, dictatorship, autocracy, oligarchy, and whatever else.

That’s a pretty full plate, and last week it looked like Senators Manchin and Sinema were on track to blow it all up — or not, as the case may be.

On Friday evening, President Biden apparently put his foot down, so let’s see what happens next.

Mercedes-Benz tops 28,500 car hybrid battery test — THIS brand came in last

Mercedes-Benz tops 28,500 car hybrid battery test — THIS brand came in last

When it comes to battery longevity, it appears that brand matters. A recent study published by Germany’s ADAC revealed tangible, real-world differences in how the high-voltage batteries in PHEVs age across manufacturers. The results: Mercedes’ batteries came out on top, Mitsubishi trailed behind.

A recent study by the German motoring group ADAC (think of it as Germany’s equivalent of America’s AAA) and data analysts at Austrian battery firm AVILOO analyzed more than 28,500 state-of-health (SoH) measurements from plug-in hybrid electric vehicles (PHEVs) across six years and several vehicle brands. While the study found that battery degradation for most brands remains within a range consistent with an average vehicle lifespan, it turns out that one of the strongest predictors of battery longevity was the brand of vehicle tested.

In other words: not all hybrid batteries are created equal, and it seems like you really do seem to get what you pay for with batteries from traditionally pricer brands like Mercedes-Benz, BMW, and Volvo out-performing those from mainstream car brands like VW, Ford, and Mitsubishi. Here’s how ADAC broke it down:

In terms of brand comparison, Mercedes-Benz models generally show very stable battery performance up to a mileage of 200,000 kilometers. This contrasts with Mitsubishi, whose PHEVs already exhibit significant degradation even at low mileages, although this stabilizes somewhat over the course of their lifespan.

Battery degradation in vehicles from the Volkswagen Group and Volvo remains within an unremarkable range even with higher proportions of electric driving. BMW models show a noticeable variation across the entire field, depending on electric usage. In Ford models, battery capacity decreases remarkably early, regardless of the specific user group. However, predictions regarding battery condition at higher mileages are not possible due to the limited number of tests.

So, what are the big takeaways here, besides the notion that more expensive products tend to be built better than cheaper ones? It seems like most PHEVs are maintaining more than 80% of their batteries’ SoH after 200,000 km (~120,000 miles), with some of the higher-performing batteries doing significantly better.

Again, the ADAC results shouldn’t be interpreted to mean that the Mitsubishi PHEV models aren’t perfectly serviceable, reliable offerings – just that some cars that cost a lot more than the Mitsubishi tend to have batteries that last a little longer under typical driving conditions.

ADAC also adds that, if frequent electric-only trips are on your agenda (as they are on mine), a fully battery-electric vehicle may be the smarter pick, as their batteries go through fewer charging cycles and tend to last longer than PHEV batteries as a consequence.

At the end of the day, it’s a straightforward choice: align your powertrain with your intended daily use, and your battery will have an easier, longer, and healthier life.

First look at Honda’s new full-size electric motorcycle

First look at Honda's new full-size electric motorcycle

At EICMA 2025, Honda finally pulled back the curtain on its first full-size electric motorcycle with the first-ever public unveiling of the Honda WN7. As someone who’s followed the electric motorcycle space for over a decade, I’ve been waiting a long time to see Big Red bring some serious voltage – and it looks like that moment has arrived.

The WN7 isn’t just a compliance bike or a modest scooter like we’ve seen for years from Honda – it’s a legitimate full-size motorcycle, albeit still a commuter motorcycle and not something you’d likely want to take on a cross-country trip.

Designed as a naked street bike in Honda’s “FUN” category, the WN7 features a peak output of 50 kW (67 hp), putting it in a similar performance class to a 600cc internal combustion motorcycle. With 100 Nm of torque, it even rivals liter-class bikes in terms of torque off the line, promising quick acceleration and agile city or highway handling.

Honda’s development team leaned into the EV strengths with a design philosophy they call “Be the wind.” The goal is apparently a ride experience that’s quiet and immersive, letting you hear the world around you while still delivering that satisfying EV torque hit.

Visually, the WN7 sports a sharp silhouette and a horizontal LED light bar up front – a design element Honda says will become the face of its entire electric lineup. It also features a new colorway exclusive to Honda’s EVs: a black body accented with golden mechanical components.

One of the most interesting engineering decisions is the frameless chassis. Instead of a traditional motorcycle frame, Honda uses the rigid aluminum battery case itself as a central structural element, connecting both the front steering head and the rear swingarm pivot directly to it. This design not only cuts weight but also improves handling by centralizing the mass. It’s a move we’re seeing more frequently, having been employed by other electric motorcycle makers such as LiveWire as part of their S2 Arrow platform.

Honda’s powertrain includes a new liquid-cooled motor with a built-in inverter, delivering its power to a belt-drive rear wheel through a newly designed gearbox. It’s quiet, clean, and torquey – just what you want in a commuter or light touring bike.

The moderately sized, fixed 9.3 kWh battery supports both CCS2 fast charging (20% to 80% in 30 minutes) and Type 2 charging, with a claimed range of 140 km (87 miles) per charge under WMTC standards. Riders also benefit from regenerative braking with customizable deceleration levels, as well as a slow-speed walk mode for precise parking assistance.

No word yet on pricing or exact market release dates, but Honda says the WN7 will be produced in Japan and rolled out in regions “where electrification is advancing.” Perhaps that could be a clue about its entry, or lack thereof, in North America.

The “Anti Tesla” deal: Polestar 3 gets an $18,000 incentive offer for November

Published

The

Polestar may not yet be a household name, but these makers of objectively excellent, sporty EVs with Scandinavian sensibilities are doing everything they can to change that — including offering killer post-rebate deals set to take the fight to Tesla.

CarsDirect is reporting a MASSIVE $18,000 lease incentive on the sporty Polestar 3, which starts at around $67,500 for the Long Range Single Motor model and goes up to approximately $79,400 for the Long Range Dual Motor. For those of you like to see the math, that pencils out to ~25% discount from MSRP.

Nationally, the 2025 Polestar 3 features a $18,000 lease incentive. Customers who lease a 2025 Polestar 3 through Polestar Financial Services will receive the brand’s $18,000 Clean Vehicle Noncash Incentive. Customers who buy a 2025 Polestar 3 with cash or through standard financing can get $10,000 Polestar Clean Vehicle Incentive cash towards the purchase.

All Polestar 3 EVs currently offer 0% APR for up to 72 months on purchases plus a $7,500 financing bonus. This is the lowest rate we’ve seen since the vehicle’s launch, and it is now among the best 0% financing deals on an SUV.

CARSDIRECT

The EV deals don’t stop there. Polestar is offering both lease and finance customers who happen Costco members can get another $1,000 off the Polestar 3, making the Swedish/Chinese crossover one of the most compelling new car deals in the business.

In the US the entry Polestar 3 Long-Range Single Motor (RWD) model starts at the previously-mentioned $67,500 MSRP (pre-rebate), and offers a 111 kWh battery pack good for an EPA-rated range of up to 350 miles. The top-shelf Performance-spec Polestar 3, meanwhile, offers an all-wheel-drive dual-motor setup that Polestar rates at 380 kW (~517 hp) that will launch you across suburbia with a 0–60 mph time in the 4 second range, albeit with slightly less range than the base model: “just” 275–315 mi, depending on wheels/trim.

The other thing a Polestar 3 offers is a bit of neutrality. Polestar hasn’t been shy about what it views as an “opportunity” to snatch up car buyers who want to distance themselves from Elon Musk and the political polarization that’s now associated with the Tesla brand.

The company’s CEO, German auto industry stalwart Michael Lohscheller, told Bloomberg, “For Germany, somebody outside of Germany endorsing right-wing political parties is a big thing. You want to know what I think about it? I think it’s totally unacceptable. Totally unacceptable. You just don’t do that. This is pure arrogance, and these things will not work.”

He’s hoping enough people agree to move the needle on Polestar sales in the US – and the first step to that is for consumers to get behind the wheel of this “masterfully tuned and sneaky-fast SUV,” and see if it’s a fit for them.

One thing is certain, though: at $18,000 less — the Polestar 3 is a lot more likely to be a fit for their budget than it was before!
