    They have been using “dyes” that change the color of LEDs by absorbing light at one frequency and re-emitting it at different frequencies for a few decades already. I have wondered if a similar process couldn’t be developed for PV cells to increase their efficiency. Guess that must be a lot harder. Still seems like these folks may be making progress in that regard. And it is just a film added in the cell manufacturing process! Could be a big deal indeed!

      That is really cool. Now that more people are getting on the PV band wagon, I hope we will see all kinds of innovations like yours and others. Keep up the interesting work.

      One thing that has ben done in watches over the last few years, are clear PV cells, basically the glass is generating enough voltage to maintain smart watches by Garmin. I have one of their solar smart watches with a PV cell and PV glass (Instinct Solar by Garmin) that can last over 50 days on a charge. No more charging every 4 days. They just released several more models this month with color touch screens, PV glass and PV cells.

        Citizen has been selling their Ecodrive watches for 25+ years. It’s all about efficiency – when you don’t need to drive a power hog display or other functions, but you just need to tell time, you don’t need much power. Sounds like Aptera, right?

    Here’s another advance, just out of “Proof of Concept” – still has a ways to go before common…

      That’s quite the sensational headline following by reporting that does very little to put it in familiar context. 1000x better than… not modern silicon PV cells, but rather some previous version using similar chemistry and no mention of the actual new or old performance values. No mention of the likely more familiar photovoltaic mineral group perovskite, which this does belong to.

      This may be something very significant or it may be just another flash in the pan; amounting to nothing more than click bait. Sure can’t tell from this repeatedly parroted press release. Think I will wait to get excited about this one.

      Guy, that article was by/for Creative Commons to sell licensing for intellectual and other creative systems. It wasn’t that it was a fake, it was just an example for them to sell more licenses.

        Hi Vernon – Yeah, the Claim of an Even 1000% was suspect, but when You have Basket Weaving and Journalism Writers covering Engineering and Science, things go all wonky. Hallmarks of a Science/Engineering Writer woud have been a statement like: “4.3 Times More Current from Identical Light Source…” or something like that. Still, there might be something there.

        I am concerned that the SLow Trip To market of the Aptera will allow other companies to have something that while not directly comparable, will appeal to the Masses, such that it takes Share from APTERA. (Annd I am Really Wanting an Aptera for MEEEE!)

        Regards, fellow Apterite!

          Guy, it may take a while to see an aptera but I bet the efficiency per watt will be hard to beat.

            “efficiency per watt”(?)

              not just per Watt (amps x volts), but CD (coefficient of drag), rolling resistance and mechanical resistance make for a very highly efficient vehicle that Aptera is building.

              I understand that Aptera 3-wheeler w/solar is likely to be a highly energy efficient vehicle. I just don’t understand the phrase “efficiency per watt”. As a “specialist” in solar cell assembly and encapsulation (as well as electrical testing of same) it just doesn’t make sense to me and was hoping to learn the meaning.

              Some of the other companies have listed how many miles per watt they can drive their vehicles. From what I’ve seen, Aptera uses about 30% less power to travel 1 mile than the closest competitor that I’ve seen.

              I understand the “context” now. Thanks for taking the time to reply.

    There is always something new, hopefully better but not always.

    Tear running down cheek, where’s my aptera, snif, snif.

    I’d be vicareously happy to see anyone driving their vary own aptera.

    Learned a new word just so I can use it in this post (vicareously).

    “Experienced with imagination through the actions of another”

    Been doing it with every new update video, hopefully by seeing some owners with them soon.

    You think Steve and Chris are commuting around with one yet? I would be.

    Thanks, Enjoy the day.
