What is: Power output per m2? Durability (life span)? Production cost? At least theoretical ...
This type of cheeky criticism is probably fair when you have a startup claiming crazy numbers with no prototype, but this is reporting on a paper from a research institution. No need for snark.
What are you talking about?! All I am trying to get some numbers, if anyone has them, but it seems amount of unhelpful comments begins to be overwhelming on HN.
I thought solar conversion efficiency was a large fraction already. There's no room for 1000x improvement. Maybe 20%. What is this title talking about?

Reminds me of my masters research at university. My work was based on hybrid organic-inorganic solar devices based on boron subphthalocyanine chloride and an optimised optical spacer layer. One day, one variation of the type of cell I was producing was over double the output efficiency of what we usually expected. Was exciting until we realised the solar testing rig had been erroneously set to the equivalent output o…
> set to the equivalent output of two suns... I didn't realize we have achieved a Kardashev Type II civilization already :)
Damn hard to get a license for that nowadays, though, no matter how important your science is.

One day… two suns. Talk about playing God. :-) That sounds like fascinating research.
For those like me, who didn't get this at first. It's about improving output from ferroelectric solar cells, a specific type of solar cells, which are easier to build than regular ones made of silicon. But they usually aren't as effective as the silicon ones.
yup, my thoughts exactly. otherwise a 1000x increase in 30%-ish efficient pv silicon-based solar cells would be far above unity
If your process is 30% efficient, it wastes 70% of input. If you increase efficiency 1000x, it wastes 70% / 1000 = 0.007% of input, so it's 99.993% efficient.

This Red widget is 1000x better than older Red widget designs. Even though Green widgets are still much better.
But red widgets might be cheaper to mass produce. Maybe. I don't know I'm knee deep in analogies now.

I mean, do we really need Jupiter as is? Everything Jupiter has done for us with clearing out the trash from the solar system would have been done by a 2nd smaller sun as well.

criticism, snark ?! What are you talking about?! All I am trying to get some numbers, if anyone has them, but it seems amount of unhelpful comments begins to be overwhelming on HN.
There was no snarky tone-of-voice in your reply when I read it. Maybe cultural differences? Please, kindly inform me of the output of the power output per m2? Also, is there any information available regarding the durability (lifespan) of the product? Who's got time to be that formal on something as an internet forum? I read topic, now here's some questions I have is perfectly fine. Some people possibly just need to get thicker skins and realize that not everyone out there is trying to be an asshole and just stop reading things in that manner.
