Scientists develop mega-thin solar cells that could be shockingly easy to produce: ‘As rapid as printing a newspaper’::These cells could be laminated onto various kinds of surfaces, such as the sails of a boat to provide power while at sea.

If it’s shockingly easy to produce then just do it and then you can write a declarative headline that doesn’t need to use the word “could”. If you can’t then I’m guessing it’s not that shockingly easy.

I mean, even if it’s easy to do, that doesn’t mean a manufacturing process is easy to ramp up. You need equipment to produce it, and people to do it. Logistics of that isn’t like just turning on/off a light switch.

Yes, exactly. My point is that I’m tired of these bullshit headlines that are implying that we have some great breakthrough; unless the discovery also accounts for everything you listed, it’s not a breakthrough and we, the public, don’t need to hear about it just so that a newspaper can sell clicks and ruin trust in science.

To echo the other individual who replied, it’s shockingly easy to make injection molded parts, but there is usually a long process before you bring the final product to market. And that’s with all the manufacturing processes already existing at scale.

In this case, the processes need to be fleshed out from scratch, which adds even more time to the ramp up. So even if the headline is 100% accurate, and there are no other roadblocks, it would still take a significant chunk of time to bring to market.

I don’t think it’s so much about thickness, but being super thin presumably means it requires less of a manufacturing process and also less raw materials. Could bring costs down on panels and make them more financially viable for projects.

Although the cells can only generate half the energy per unit area compared to traditional silicon panels, they can generate 18 times more power per kilogram, Fast Company reported.

For most users, I’d guess that unit area is more important. But for satellites, I suppose that as long as they can unfold, space isn’t really an issue. You’ve got all of outer space to spread out into. But weight determines a lot of the cost of putting the thing up in space, so you’d like that to be low.

If they’re cheap enough, you can just slap them on any available surface that gets a marginal amount of sunlight. Doubly so if they’re flexible.

Weight does play a huge role for satellites and to be honest I have very little knowledge of solar panels they use. However since solar sail is a thing, I’d argue surface is indeed a factor with satellites. But perhaps they managed to get some use there. There might be even other use cases I just didn’t think about. My original comment was mostly pointing out that thickness was rarely as big of an issue as it was efficiency.

For anything other than house roof solar price per kw is going to be the deciding factor. Rural land is very cheap compared to solar panels - we’re talking about a 100:1 cost ratio.

Use cases increase if they are thin. Instead of limited to rooftops. For example, take a look at what Aptera is doing.

Clearly you’ve never owned an air fryer wanted a solar powered car. Or imagine shipping containers covered in these powering the trucks that haul them! Or trains! Even boats. Basically any kind of self powered transit, especially ones with greater surface area.

Second edit: Another idea! Clingfilm solar panels for windows, or blinds and curtains that can power the lights!

Or wind turbines skinned in thin, light, flexible solar panels. You’d double dip on energy per square meter. You could have a solar farm on a stick that also makes wind energy.

If you dream of covering a vehicle with panels and have it driven by that power, I have to burst your bubble. That’s not even nearly enough surface to generate enough power. Perhaps assist in trickle charging battery, sure. But we already have flexible panels, even self-adhesive ones. And again, their biggest downside is not their thickness but efficiency. There will never be a self-propelled vehicle. Just a nature of things.

As for window blinds, etc. There is already glass that lets enough light through and can generate electricity. Those are even worse when it comes to efficiency due to non-ideal angle, light passing through, etc.

“We already have technology that doesn’t do those things well enough, so this new technology that won’t see advancement ever has no chance of addressing these issues either.”

Trickle charge is awesome. Trickle charge the semi during your 8 hour driving shift and then another 8 hours while the trucker is asleep. If that nets half a charge every other day, that’s a charge and a half a week. It’s not self powered like a perpetual motion device, those aren’t real. But regenerative braking is a worthwhile addition to an electric truck. Why wouldn’t solar paper or whatever we want to call it also be part of the solution?

Those all sound like efficiency issues still. Covering any form of transportation with solar panels is primarily pointless because of how little power that would generate. Even if you covered every available inch with the most efficient panels invented, it would take over two weeks of sitting in full, direct sunlight to charge a solar-powered car, which you would drain in four hours of driving. As these panels are half as efficient as traditional panels, you could drive maybe a two minutes per hour you sit in full sun.

First, the thickness factor plays into flexibility. Just imagine surfaces of every shape being covered in solar cells. Flexible panels could also be less prone to breakage.

Second, with “as rapid as printing a newspaper”, this might be a major cost-reduction thing, even on top of the process needing less high-pure Si material.

This might make solar power generation more attractive even if the efficiency would be lower than other methods, because this would drive the ratio $/kw down.

Kind of like these? Flexible solar panels are not a problem. And no, being newspaper thin will never be stronger than mounted on rigid surface. If it bends it has a definite limit in number of times you can bend it.

As for “printing a newspaper” and rapid production, when I see it I’ll believe it. At the moment it’s nothing more than speculation as they themselves have not made it yet. Every manufacturing process starts slow and then speeds up as process is optimized. The problem is whether there is a financial incentive to start producing in the first place.

By “flexible” I did not imply “use it as a hinge”. It was more like: “you can install it on a non-flat surface”, e.g. by gluing it down. Now that surface would provide the needed overall stability. Imagine having you cars roof and engine hood being completely covered in solar cells - or basically be a solar cell. No, you would not be able to drive it as an EV with the amounts of power provided, but it could trickle charge a battery, or power a fan in hot weather so the interior will not be boiling when you return to your vehicle after a day at work.

It’s a different process. Multiple processes with varied applications are absolutely essential to making this style of solar the norm

It’s a great thing that this particular field continues to see innovation.

New process

Scientists used electronic printable inks, using a technique similar to how designs are printed on t-shirts. As these thin solar cells are difficult to handle and can tear easily, scientists searched for a lightweight, flexible, and resilient material that could adhere to those solar cells. The fabric they chose was Dyneema Composite Fabric, a material known for its incredible strength.

After printing the electrodes on a flat sheet of plastic, they glued the sheet of plastic on Dyneema. Lastly, they peeled away the fabric, which has picked up the electrodes, leaving a clean sheet of plastic behind.

Your linked process:

The organic solar cells being deployed have been printed on laminated polyethylene terephthalate (PET) plastic by a printer formerly used for wine labels.

The 18 metre long ultralight and ultraflexible strips are similar in thickness and appearance to a chip packet, the university team have said.
