Believe it or don’t, the last time I crunched the numbers, it was the Selenium in CIGS that they’re having the most trouble unlocking more of.

Ah, the magic five years. Whenever you see someone say it's five years away it means they have no idea when, or if it'll come to market.
And yet your linked chart shows datapoints >40%. What gives?
They list 31% efficiencies for their cells that can fly today which must be near the limit of commercialization / certification. Still pretty good though, that’s 50% more efficient than a standard panel, and at several $10s of thousands per kg into space, clearly worth it!
Which seems about right, but what I didn't realize is that they're shipping >40% concentrators too. That's pretty great!
(That last link was supposed to be for the concentrator section at the bottom of that page, but I don't think it's a normal # bookmark)
That said, they would only make sense in places where space is at a premium so people are willing to pay extra for something a bit smaller. That's not especially common in home use.
Commercial means what you can buy at reasonable prices.
It takes some time from knowing something is possible, experimental technology, like multitouch controlled computers, and companies selling them in the billions, like multitouch being in every Ipad or smartphone.
I guess the hope is that they will command less of a relative premium compared to multijunction silicon cells?
I wonder if Organic Solar Cells fix this?
Or some day where we could produce Windows Glasses that absorb some of the UV and turns it into electricity for cheap. I know we have the tech but it seems still to expensive for now.
In the countryside, things are different: you have massive installations close to ground level, often at hillside slopes, and if you happen to drive on a road towards one of those at that special time of day/year when the reflection goes straight into oncoming traffic you are left with staying calm and hoping for the best. Happened to me on an unrestricted stretch of Autobahn, slowing down where everybody else is also blinded would be a very, very bad idea. As I said, stay calm and hope for the best. I could really see a case for building codes to get updated to prevent such things (the position of the sun over the course of the year is perfectly predictable) and maybe even a revival of heliostat installations for sites where this can be an issue.
Non-native English speaker here: Is there a word to describe something which is transparent but alters colour?
The title set up sounds like a lazy scientist joke : technically you can call planting a forest, call them organic solar cells and burn them later for a non-direct electricity solution without doing any research.
I dont understand nearly enough about materials science to grok how you iterate to such a discovery. Does anyone else have intimate knowledge of the grind?
Generally what happens is a simple theoretical model predicts what the most efficient compounds to try are - but not all their properties can be predicted theoretically. So somebody has to try them and find out what all the handling and fabrication difficulties are, then develop solutions for the sub-problems.
(Does anyone have the scihub link to the actual study referenced in the article?)
For one thing, it generates energy for just when the sun is shining and no clouds overhead, which aren't usually peak hours. There are other problems as well. https://sciencing.com/future-solar-power-obstacles-problems-...
I'm waiting for Fusion power...
First, it was always 30 years away, then 15 years, now it's down to 10 years. Not sure how to determine the asymptote, but it'll doubtless happen with the Singularity.

Nuclear fusion is 15 years away from reality, say MIT engineers
