If you have never experienced having some solar panels with an inverter and a small inexpensive battery like a $30 10 amp hour lithium iron phosphate battery then you really can't understand the dramatic gains that have happened in solar panels lately. Suddenly you have an immense amount of power being put out by something that's just sitting there in the sunshine that's not even very big. We're talking about power that can kill you coming out of an inverter. We're talking about power that can make a Big Arc of electricity. Two or three Solar panels today can make whopping amounts of power and not even in bright sunshine. They'll make power even in cloudy skies.
When can I buy one? I'm about to install a roof worth of solar but this stuff could probably just use 1 or 2 panels. Worth waiting vs electrical savings now??
I just keep the thumbnails as small as possible, completely removed when just viewing the whole subreddit and such. It's quite often they're really not related, showing some random picture of a dude or something like this. At least in my experience.
It is amazing how 'inefficient' power 'generation' seems to be. Imagine if they were 99% efficient. I guess that would be like imagining I was 26.81% efficient.
There is a technical limit, about 34%, so we are 80% there. To go beyond that you have to use multi junction cells, which are a lot more expensive. Perovskite does multi cell, but with efficiency level similar to conventional methods
I think it means there’s lots of room for further efficiency improvements. And solar is already the cheapest way to produce energy…imagine what will happen if efficiency continues to rise
I guess if your goal is to pay many times as much for the same amount of energy, sure... it's pretty "green" when the waste is handled well, it's just suuuuper expensive compared to solar right now.
If you had a field of these 26.81% efficient solar panels in the same footprint of a nuclear power plant (including all off limit areas and borders), this would generate the same amount of electricity. Throw some batteries in there and you've got yourself a much better system in that you don't need to wait 10 years to put it up.
I just wish the prices would come down. I still got quoted over $20,000 for a 6kW system for my house. The payback time was 30 years with only a 25 year lifetime on the panels.
They have come down in cost rapidly, and don’t seem to have stopped. The cost per watt is about a fifth of what it was a decade ago, and we’ve blown way ahead of forecasts from that period. Also 30 year payback time? That’s extremely atypical from my own research into this.
Name me one company in the world. That doesn't use the Chinese slave labor getting the minerals. China has the rare minerals market cornered, because its polluting as fuck and no one wants it in their country.

Interesting. It makes me wonder if some boats will move to at least partially electric motors. Keep the diesel for when it's needed.

Why is the thumbnail just a photo of some dude? Yes, I read the article.
I, personally, prefer seeing an image of the actual technology that's being reported. Couldn't care less about the guy, who managed the engineers.
He's actually a solar cell
Maybe because he's a VP and head of R&D for the company in question?

Here is an article with technical details if anyone is interested.
World changing. I can’t wait for 27% efficiency.
Bro 28 is gonna be lit

Energy conversion is a tough game.
There is a technical limit, about 34%, so we are 80% there. To go beyond that you have to use multi junction cells, which are a lot more expensive. Perovskite does multi cell, but with efficiency level similar to conventional methods
Photosynthesis in plants is typically 3%. Solar cells are fighting thermodynamics, so almost 27% is extraordinarily good.
Muscles are about 30% energy efficient, so you’re not far off
I think it means there’s lots of room for further efficiency improvements. And solar is already the cheapest way to produce energy…imagine what will happen if efficiency continues to rise
What does large size mean in this context? Article didn't say that I could see.
Probably a full wafer. There are a few different standard sizes nowadays, but all of them are around 6-8 inch squares or rectangles.
Most records are set by thumbnail sized cells. These are full sized cells.

Still need both. It's not either-or.
Oh cool, which brand of nuclear do you suggest for my rooftop?

Nuclear is the single best option. Still fascinating people argue against it.
Some people that want their investment to pay back within a decade.
Only if everyone can keep the toxic waste in your bedroom.
What do you think the Sun runs on?
Shiiiiit. They better get on it, Wish is selling panels with 8,000,000% effeciency!
Wish went too far, now they will only sell a single panel and a lightbulb. Breaking laws of thermodynamics isn't a smart business move.
I just wish the prices would come down. I still got quoted over $20,000 for a 6kW system for my house. The payback time was 30 years with only a 25 year lifetime on the panels.
I got a quote 23k for 9kw so yours is really high. With rebate I'm looking at 9.9 years

Using chinese slave labor getting minerals from african slave labor ccp = trash

Chinese fluff oriented “news”
Now we just need some cheap batteries, current solar pannels are at 22% so i dont see such a big efficiency increase
Who is the most efficient? By spatial and energy efficiency? Definitely not this.
I’ve been waiting 20 years for cost-efficient solar panels. Looks like it’ll be at least another few decades…
Wake me up when we get to the 80s
I swear it's a new record every week. I'm holding out until 99.9%.
