Perovskite solar cells (22.1%+ efficiency)

[itsmeagain]

Anyone know much about Perovskite solar cells?

After reading Bob's post about possible upcoming changes in solar prices, I did a little digging about solar tech and ran across Perovskite solar cells, but didn't find any info on it on this forum.

Here are two articles less than 48 hours old:

And of course, no new tech would be complete without a TED talks:
(not the most dynamic speaker, but good info)

Think this might be on the horizion any time soon?

Apparently they're cost effective to produce.
They're claiming 22.1% efficiency now, and they're stating they can get that much higher.

Sunpower cells already in that ballpark no?

My 435w is a rebreanded SunPower. It has a efficiency of over 20% and while rated at 79.9 Voc, it produces over 100 Voc.

I have seen quite a few advancement in solar never make it to market. It takes more than a good product, you have to make money at it. Also it may be a bit better but it takes more than just a small improvement before people will be willing to spend extra money on it or replace what they have,

There has been constant talk of breakthroughs in batteries and solar--none of it has happened yet.

Reminds me of the saying that "Perfect is the enemy of good enough".

Stop worrying about a "perfect" system and get out there with one that is "good enough".

right?  like a spilled sack of potatoes.


I figured it was worth a post, but had a sneaking suspicion it might be just hype, especially after not finding anything on it here.
Thanks!!
