Researchers led by Australia’s national science agency had an efficiency breakthrough with roll-to-roll flexible printed perovskite solar cells.
The international team, led by the Australian government’s Commonwealth Scientific and Industrial Research Organisation (CSIRO), has developed a new method for producing roll-to-roll flexible printed solar cells that deliver unprecedented levels of efficiency.
Printed solar cells are highly efficient, flexible, and decreasing in cost. Unlike traditional silicon panels, solar cells could be deployed in previously impossible ways to generate energy from the sun, including on buildings, vehicles, and wearables.
However, scaling up production while maintaining efficiency has long been a hurdle for printed solar cell technology. Many researchers have only achieved 1-2% efficiency levels with a full printed flexible solar panel.
The CSIRO team achieved lab-scale solar cells with 11% efficiency for 50 sq-cm large-scale solar panels comprising interconnected perovskite solar cells.
Perovskite and printing presses
Perovskite can be formulated into inks and printed on widely available industrial printers. It’s lightweight and flexible, which makes it portable and versatile in its potential applications.
The perovskite solar cells are printed using a roll-to-roll technique similar to newspaper printing, which allows for continuous, large-scale production.
While roll-to-roll production of perovskite solar cells isn’t new, existing technology has faced limitations in efficiency and scalability.
The CSIRO-led scientists used automated fabricated and screening systems capable of producing and testing more than 10,000 solar cells a day, enabling them to pinpoint the ideal settings for various parameters quickly. That led to a substantial increase in efficiency outcomes.
The CSIRO-led team says the dramatic increase in efficiency has paved the way for commercially viable perovskite solar cell manufacture at scale.
The roll-to-roll printed perovskite solar cells’ shorter energy payback time and projected low costs make it an economical and environmentally attractive renewable energy solution. It also eliminates the need to use expensive metals like gold in production by using specialized carbon inks, substantially lowering manufacturing costs.
CSIRO is now actively seeking industry partners to further develop and commercialize the technology. CSIRO collaborated with researchers from the University of Cambridge, Monash University, the University of Sydney, and the University of New South Wales. The research is published in the journal Nature Communications.

Tesla (TSLA) released its financial results and shareholders’ letter for the third quarter (Q4) 2025 after market close today.
We are updating this post with all the details from the financial results, shareholders’ letter, and the conference call later tonight. Refresh for the latest information.
Tesla Q3 2025 earnings expectations
As we reported in our Tesla Q3 2025 earnings preview yesterday, the Wall Street consensus for this quarter was $26.457 billion in revenue and earnings of $0.55 per share.
It would represent a record quarter in terms of revenue, thanks to record deliveries due to demand being pulled forward into Q3 in the US, amid the end of the federal tax credit for electric vehicles.

However, the expectations suggest that Tesla’s earnings are continuing to erode despite the positive temporary circumstances of the third quarter.
How did Tesla do compared to expectations?
Tesla Q3 2025 financial results
After the market closed today, Tesla released its financial results for the first quarter and confirmed that it delivered below expectations with earnings of $0.50per share (non-GAAP), and it exceeded revenue expectations with $28,095 billion during the last quarter.
This is quite disappointing, considering Tesla’s operating income decreased by 40% year-over-year, despite achieving record revenue.
The difference is accounted for by a decrease in gross margin from 19.8% to 18%. In part due to Tesla losing some regulatory credits and lowering prices across most products.
Bulls also can’t explain this by Tesla investing in the future, as capex is significantly down year-over-year.
Nonetheless, the automaker added to its war chest, which now sits at $41.6 billion.
We will be posting our follow-up posts here about the earnings and conference call to expand on the most important points (refresh the page to see the most recent posts):

Jeep and Ram’s parent company, Stellantis, is pushing back two more electric vehicles that were due out next year. The delay is the latest in a series of delays or plans to cancel what were considered key EVs.
Stellantis delays Alfa Romeo Giulia and Stelvio EVs
Add it to the growing list of electric vehicles that have recently been delayed or cancelled altogether. The current gas-powered Alfa Romeo Giulia and Stelvio will live on for at least another year in the US.
Initial plans called for both to arrive as next-gen variants in 2026, offered exclusively with electric powertrains. Stellantis is now delaying the EV versions for another year and will continue selling the current models until Alfa Romeo is ready to adopt the STLA Large platform.
Stellantis CEO Santo Ficili announced the news during a presentation for the updated Tonale SUV, according to a report from Motor1.

Stellantis is delaying the EV variants to give Alfa Romeo more time to fit the next-gen Giulia and Stelvio on the STLA Large platform with gas engines. Although it’s not confirmed, the replacements will likely use the same twin-turbo inline-six “Hurricane” as the Dodge Charger Sixpack.
The announcement follows Stellantis’ decision to cancel Ram’s first electric pickup, the Ram 1500 REV. Instead, Ram will focus on the range-extended version.

Stellantis also cut the base R/T trim from the Dodge Charger EV lineup and reportedly shelved plans for a range-topping SRT Banshee model.
Ram and Jeep plan to bring back the HEMI engine for the Ram 1500 and Wrangler Rubicon 392, while the 2026 Dodge Durango will be exclusively available with a HEMI.
While Stellantis is shifting plans, at least one EV is still on track. Jeep’s CEO Bob Broderdorf confirmed the Recon EV, its “Wrangler-inspired” electric off-roader, will debut soon with sales starting next Spring.

Tesla has released its latest Autopilot safety report, and the limitations are still presented misleadingly; however, one clear thing is that the data is worsening.
Tesla notoriously doesn’t release any relevant data to prove the safety of its ADAS systems: Autopilot and Full Self-Driving (Supervised).
The only thing the automaker releases is its quarterly “Autopilot safety reports”, which consist of Tesla releasing the miles driven between crashes for Tesla vehicles with Autopilot features turned on, and comparing that with the miles driven by vehicles with Autopilot technology with the features not turned on, as well as the US average mileage between crashes.
There are three major problems with these reports:
Advertisement – scroll for more content
Methodology is self‑reported. Tesla counts only crashes that trigger an airbag or restraint; minor bumps are excluded, and raw crash counts or VMT are not disclosed.
Road type bias. Autopilot is mainly used on limited‑access highways—already the safest roads—while the federal baseline blends all road classes. Meaning there are more crashes per mile on city streets than highways.
Driver mix & fleet age. Tesla drivers skew newer‑vehicle, higher‑income, and tech‑enthusiast; these demographics typically crash less.
With all these flaws in Tesla’s quarterly Autopilot safety reports, the primary value lies in comparing the miles between crashes with Autopilot features turned on over time.
However, there are reasons to believe Tesla’s data now, as it doesn’t look good for the company.
Here’s Tesla’s latest report for Q3 2025:
In the 3rd quarter, we recorded one crash for every 6.36 million miles driven in which drivers were using Autopilot technology. For drivers who were not using Autopilot technology, we recorded one crash for every 993,000 miles driven. By comparison, the most recent data available from NHTSA and FHWA (from 2023) shows that in the United States there was an automobile crash approximately every 702,000 miles.
It’s now the third quarter in a row where Tesla had a year-over-year decline in mileage between crashes:
The data deteriorated enough that Tesla had to give up its misleading claim that “Autopilot is safer than human by 10x” and now says “9x” instead:
The comment is still misleading for the previously mentioned reasons and should be labeled as “Autopilot + human driver” as it requires driver attention at all times.
There’s no way to know how many accidents human drivers prevented during Autopilot mileage.
Electrek’s Take
Again, I have to emphasize that this report only has value when you compare the Autopilot mileage against itself over time.
It’s also important to compare the same periods year-over-year as accidents are more common during the winter due to people driving more often after dark and in more difficult conditions.
Therefore, the only important thing that this report highlights is that Autopilot is getting worse.
Shouldn’t that be worrying? Shouldn’t Tesla address that instead of falsely claiming it means Autopilot is 10x, 9x safer than humans?
