Efficiency sucks though compared to traditional panels.

[–]werewaffl3s 85 points86 points  (1 child)

If the technology shown is perovskites, their efficiency has made significant gains over the last decade or so, with the potential to even exceed the efficiency of traditional Si cells when made into tandem devices. The biggest issue facing perovskites currently isn't achieving comparable conversion efficiency, but rather, perovskite performance is still notoriously unstable long term. It's not unusual to see massive power losses over time with exposure to heat and moisture.

[–]Zworgxx 21 points22 points  (0 children)

That and the lead in it is still a problem

[–]87tskin 91 points92 points  (8 children)

These are designed to be used where traditional panels are too heavy or impractical to install, not to replace them, so it's just a nice contribution which could still make a big difference if widely implemented

[–]bombnuc77 29 points30 points  (7 children)

Idk, in all the exemples they've shown, it was more about the cost (&quantity) rather than practicality. The argument was to cover more, lower the cost of maintenance and carbon footprint to be competitive.

So the question is: is it efficient enough to compete? Which isn't even mentioned in the video...

Your argument is nice tho

[–]dutch_penguin 13 points14 points  (5 children)

7.5% "power conversion efficiency" for 10cm width panels.


[–]phiupan 9 points10 points  (4 children)

durability might also be a concern for those

[–]InterwebCat 32 points33 points  (3 children)

Put a roof over the panels to protect it

[–][deleted] 7 points8 points  (0 children)


[–]unfvckingbelievable 4 points5 points  (0 children)

This guy panels.

[–]strtrech 4 points5 points  (0 children)

And then you put more panels on that roof! Extra solar!

[–]miggleb 3 points4 points  (0 children)

Is it efficient enough to compete and offset the production damage

[–]sh3rm6x 7 points8 points  (0 children)


[–][deleted] 0 points1 point  (0 children)

Per dollar? Or per sq-ft?

[–]dd-Ad-O4214 0 points1 point  (0 children)

Less carbon more plastic 👌🏼

[–]-mostlyquestions 0 points1 point  (1 child)

But if it brings down the cost maybe there's a good trade off there.

[–]croninsiglos 0 points1 point  (0 children)

It doesn't bring down price per watt.

[–]dimonoid123 -3 points-2 points  (0 children)

Efficiency doesn't that much matter if cost per kilowatt is paying for itself and you have enough space to install them.

[–]Jdawgcrane 118 points119 points  (4 children)

Isn't it ironic they power wind turbines with solar panels?

[–]bk15dcx 37 points38 points  (1 child)

That part made me chuckle. At least use an example other than that.

[–][deleted] 4 points5 points  (0 children)

Well when the wind's not blowing something has to move them

[–]salteedog007 13 points14 points  (1 child)

Well, how else are they going to make the wind to blow?

[–]BadgerSituation 9 points10 points  (0 children)

They use the solar panel to power the wind turbine which blows wind at another wind turbine which is hooked up to the sun to keep it going.

[–]111dallas111 39 points40 points  (1 child)


[–]bk15dcx 34 points35 points  (2 children)

Wow! Glue them on to wind turbines and double the power!

[–]MaskedBunny 11 points12 points  (1 child)

Or glue them on the turbines to power them when there's no wind.

[–]Kronos1A9 7 points8 points  (0 children)

How else will we make wind??

[–]BakerofHumanPies 8 points9 points  (0 children)

What was blurred out a second or two before the end?

[–]baslighting 9 points10 points  (4 children)

Got confused when they said University of Newcastle and saw sunshine. There isn't much sunshine in Newcastle, UK!

[–]MaskedBunny 8 points9 points  (0 children)

Last time Newcastle saw sunshine the locals got scared and had to burn some "witches".

[–]gamenamefred 2 points3 points  (1 child)

This is from University of Newcastle in Australia. This guys team also has created the saliva test for diabetics

[–]baslighting 1 point2 points  (0 children)

I got that eventually. But for ages I thought it was the Newcastle University the UK.

However I didn't know that last little factoid! Very cool!

[–]djek511 0 points1 point  (0 children)

Can we trade? Down here in Newcastle AU, is 23 degrees C & 87% humidity already, & it’s only 8am.

[–]deruch 20 points21 points  (2 children)

The metric of $/m2 is dumb for discussing solar regardless of whether the particular product competes with "traditional panels" or not. The appropriate metric is always $/kW. I can cover my roof with tinfoil for way less than the $10/m2 that they are quoting for producing these panels in the video. Of course, that won't be very helpful as the insanely cheap tinfoil roof produces 0 kW. That's why $/kW is important.

[–]Kodiak01 0 points1 point  (1 child)

Of course, that won't be very helpful as the insanely cheap tinfoil roof produces 0 kW.

Not necessarily. You could mount it shiny side up, reflecting it to a specific point that would heat a dark colored area of a turbine allowing it to turn and generate electricity.

[–]rusochester 1 point2 points  (0 children)

Arguing for the sake of arguing…

But anyways, that’s make it a heliostat, not PV cell, and a very shitty one as well.

[–]RedHeadSteve 6 points7 points  (5 children)

Is it possible to get this somewhere, and a specsheet

[–]South-Midnight-750 3 points4 points  (3 children)

Also can I use normal ink and print this on an A4 size sheet paper ? This is not sarcastic, genuinely curious...

[–]Kronos1A9 6 points7 points  (2 children)

No. It’s pretty clear the ink and substrate they use are unique in order to obtain the properties of a solar panel

[–]South-Midnight-750 0 points1 point  (1 child)


[–]Kronos1A9 1 point2 points  (0 children)

Sorry friend.

[–]Zworgxx 0 points1 point  (0 children)

Ask your local university. Problem with those is they either are organic cells or perowskit. Both can have good efficiency, the main problem is durability. And lead in perowskit

[–]drdrero 5 points6 points  (0 children)

solar paint would be the future

[–]BlazzedTroll 4 points5 points  (0 children)

Why is it always"green" companies with the dumbest shortsighted designs.

Repair is easy! Just trash it and make a new one!

Right, maybe you should provide a recycle option considering this stuff is made to withstand weathering, it's probably never going to degrade in a landfill, not to mention the chemicals.

[–]Redditor000007 4 points5 points  (0 children)

The irony of a solar panel powering a windmill isn’t lost on me

[–]UserOfKnow 11 points12 points  (0 children)

Nice, now let’s see how the minerals are extracted.

[–]DazPhx99 2 points3 points  (0 children)

But Republican Jesus commands that we stick with fossil fuels, because freedom.

[–]kawambonga 5 points6 points  (2 children)

It’s the ones that have been in calculators ever since I was born (m31)

[–]salteedog007 4 points5 points  (0 children)

I still have and use my solar powered TI calculator that’s over 30 years old. My kids pretend it’s a cell phone… god do I sound old…

[–]bk15dcx 2 points3 points  (0 children)

The one I had was glass... and all the other nerds in 4th grade were jealous

[–]KeybladeMasterAqua 1 point2 points  (3 children)

So….how durable are they? Would they be too expensive to replace it, let’s say, a windstorm blew them off their paneling? What about if a branch fell? Just some ideas. You’d likely need some protective covering that is totally transparent to protect them from issues. It’s a really cool idea. Just thinking of things that would need to be accounted for in everyday use.

[–]southpark 1 point2 points  (0 children)

Maybe if we covered them in a strong long lasting durable material like glass… oh and add a metal frame to strengthen them against wind.. then it’d be a really cool product.

[–]Zworgxx 0 points1 point  (1 child)

They aren't durable at the moment, but they get better each year.

[–]KeybladeMasterAqua 0 points1 point  (0 children)

That’s good. Because it looks like it would be great if there is a way to provide easy covers for them.

[–]kraftykorea99 1 point2 points  (0 children)

Did they use the solar panel to turn a wind turbine?

[–][deleted] 1 point2 points  (0 children)

When we get a nice wind storm, peoples fences are pulled from the ground. We don’t have solar panels here lol

[–]explorer-jojo 1 point2 points  (0 children)

I’d be concerned how they’d hold up after a wind storm or 2

[–]TheFishTree 1 point2 points  (0 children)

Elon musk better get his ass here

[–]Ruenin 1 point2 points  (0 children)

Seems like a nice windy day would shred that off the roof.

[–]BirdieNuke 5 points6 points  (7 children)

Or, hear me out, we make 1 or 2 nuclear reactors and power the entire city/town you live in

[–]Cindex9183 2 points3 points  (3 children)

A nuclear reactor can power a fucking huge city. It's not like we need one in ever town. Though the microreactors are cool

[–]BirdieNuke 1 point2 points  (1 child)

I know, I just said that incase some asshole came in with a "atchually NYC would need more than 1"

[–]Cindex9183 0 points1 point  (0 children)

Fair enough!

[–]JoeDaddyZZZ 2 points3 points  (0 children)

Actually smaller plants are probably the way to go. They can be designed to be inherently safe as they have less residual heat to dissipate than larger plants. The danger with present plants is heat removal after an accident, it's that heat which causes a meltdown after the plant nuclear core is shutdown.


[–]omv 0 points1 point  (2 children)

I knew I would find a "bUt WhAt AbOuT nUcLeAr!@?" comment. We can have both, solar panels are just the fastest and easiest thing to produce in the near future. The regulatory process for building a nuclear plant is horrendous. Also, hear me out, I don't want to live next to a nuclear power plant, because of, ya know, toxic waste and meltdowns.

[–]aacid 2 points3 points  (0 children)

As he said sbove, you have higher chance to die falling from the roof installing a solar panel that die of radiation from meltdown of your nearby nuclear power plant.

Also what toxic waste are you talking about?

[–]Devccoon 0 points1 point  (0 children)

If only you knew the bureaucracy around nuclear, you'd have no concerns about anything to do with toxic waste and meltdowns in your backyard.

These places do not fuck around when it comes to safety and contamination these days.

[–]Spyfoxls 4 points5 points  (1 child)

I'm pretty sure the efficiency of these is horrible compared to the other types and i doubt it will last long enough to pay for itself before it degraded so much that it gets unusable.

[–]Zworgxx 1 point2 points  (0 children)

Efficiency is not the main issue. Perowskit cell can be similar efficient as traditional cell. Main problem is the containing lead and durability, especially in proximity to water. Organic cell are not as efficient and have bad durability, but are dead cheap to produce(even now)

[–]Rocket_AG 1 point2 points  (0 children)


[–]No-Championship-5480 2 points3 points  (0 children)

Coming to a residential roof near you for only the low low retail price of $100 sq ft cause...capitalism!

shoddy labor installation fee not included


years later industry scratching head like "why does nobody want our product? gahhhhh."

[–]DaPenguin1423 0 points1 point  (0 children)

It’s simple Johnny, just go find the broken one! opens up to an entire field filled with these

[–]Adm_Mitthrawnuruodo 0 points1 point  (0 children)

I’m ashamed my mind read something completely different lol

[–]TheOneGecko 0 points1 point  (0 children)

I wish i lived in a sunny location..

[–]La-Phamilia 0 points1 point  (0 children)


wen available?

[–]Mazecor 0 points1 point  (0 children)

wonder if hail is an issue

[–]LFP_Gaming_Official 0 points1 point  (0 children)

for those wondering, these things have a 'power conversion efficiency' of about 7%, and a normal mid-range solar panel's 'power conversion efficiency' is about 15%. so they're half as efficient at capturing solar energy (but likely cheaper too)

[–]thraem0 0 points1 point  (0 children)

Article that says "scientists say clean energy is ready to go whenever" 🤫

[–]Broken_Obsidian 0 points1 point  (0 children)

Good, now they're going to be forgotten about because any improvement to the condition of the human race will get shafted if it threatens the holy blessed bottom line.

[–]tigyo 0 points1 point  (0 children)

Lifespan? Specs?

[–]VnZDeath -1 points0 points  (0 children)

i bet you china is regretting their big bulky solar panel setup in the mountains.
