Solar Panels That Work at Night: The Next Big Leap in Renewable Energy - discoverwildscience
(discoverwildscience.com)
Lunarpunk is a subgenre of solarpunk with a darker aesthetic. It portrays the nightlife, spirituality, and more introspective side of solarpunk utopias. It can be defined as "Witchy Solarpunk." Aesthetically, lunarpunk usually is presented with pinks, purples, blues, black, and silver with an almost omnipresence of bioluminescent plants and especially mushrooms

Bullshit article based on absolutely nothing. Not even a single theoretical paper is mentioned in the article much less lab or a real world device.
"Maybe it could be done with thermo electric cooling" isn't legitimate news. It's a speculative opinion.
Pretty sure it's AI generated but Stanford has been working on it. As of 2022 their panels could generate 50 milliwatts per square meter at night. Definitely far cry from the 200 watts per square meter during the day but I also don't know how much power is used at night vs the day (guessing not that little).
The team has said they have ideas to greatly increase output but again no idea how much.
Yes 50 milliwatts is what googling says you can get from tegs. And the delta T giving 50 milliwatts drops to 0 in an hour after the panel cools to ambient at night.
That's why the article is such bullshit. A basic understanding of heat can prove there's not significant energy that can be harvested from a slab of glass going from 30C to 0C even at 100% efficiency.
Without even doing the math I'm screaming, "How long do they think solar panels take to cool down?!" Hell, they start cooling long before actual sundown.
SOURCE: I'm outside at sundown nearly every day.
If it's only 50mW it seems like it wouldn't be worth whatever the extra cost is to roll this out for anything except super niche applications. Even off grid you're probably just better off saving solar in a battery or putting up a small windmill.
4000:1 is pretty bad. Also, you presumably only get that on a clear night.
Depending on the climate peak load often occurs just after sunset as people get home, take showers, and cook dinner.
Minimum overnight load is maybe a tenth to a third of daytime loads depending on which way the incentives operate.

Such as this? This article is about it being developed 3 years ago . Totally valid to question an article. Please keep comments constructive if possible.
Where are those links in the article posted?
It is constructive to let people know they shouldn't waste their time reading an article that says nothing.
I found those without much effort. I didn't say they were in the article. Just showing it's not necessarily theoretical which was your opinion. Calling something "bullshit" can come across as unnecessarily combative and you then just dismissed the article outright. Constructive would be to state why and what about it could be improved which is more appreciated. People are free to read for themselves.
Those links are useful. If the article included it it would be a useful article.
I did. I said it had no sources.
That's a criticism which is yours to have though it is not constructive nor is this. Your comment called it "bullshit" and effectively said "fake news". I made a simple request to be more mindful of your words. Pushing back further isn't appreciated.
