New KAUST tandem solar cell breaks efficiency world record

The dynamic duo of silicon and perovskite continue their rampage through the solar cell industry. Researchers at King Abdullah University of Science and Technology (KAUST) have developed a new silicon/perovskite tandem solar cell with a record-breaking efficiency.

The dynamic duo of silicon and perovskite continue their rampage through the solar cell industry. Researchers at King Abdullah University of Science and Technology (KAUST) have developed a new silicon/perovskite tandem solar cell with a record-breaking efficiency.

Most commercial solar cells have traditionally been made with silicon as the active ingredient, and this has gotten the tech into widespread use. But unfortunately, these solar cells are starting to bump up against the physical limits of silicon’s efficiency, so there isn’t much more room left for improvement without radically changing the recipe.

Enter perovskite. This crystalline material has quickly shot up the ranks from under 4% efficiency in 2009 to over 25% by 2021 to rival silicon, and it’s not done yet. When the two materials are forced to work together, they achieve even better results, with efficiencies recently reaching well over 30%.

Better and betters solar!!! Closer to replacing coal and other crappy energy sources. You should look at pictures of china and india to know what I mean.

You should wake up as to why China, as well as India and Pakistan, are building coal-fired power plants in huge numbers.

And wake up to the insanity of wind/ solar and batteries, batteries that at best could provide a few hours of backup.

Good News, everyone!

This marks a 0.7% increase over the previous record-holder: a cell with 32.5% efficiency developed by a team at Helmholtz Zentrum Berlin and announced last December. These broken records are coming thick and fast lately – just two years earlier efficiency was yet to crack the 30% barrier.

This could be the main reason why the Fed "Reserve" banks are always having money "printed" to keep the entire banking system from failing:

An efficiency ratio of 50% or under is considered optimal.

LOL.

Because they can buy the Coal from the US. In case you aren't aware of it, in the latter years, China has been the United States Coal Customer and will continue to be. But what they do to their own environment shouldn't justify us screwing the pooch on ours.

For every kilo of CO2 that we remove from production, China adds 1,000,0000.

It doesn't take a rocket scientist to figure out that all we are doing is destroying our economy for china's benefit.

Then we need to divorce ourselves from purchasing chinese junk.

Ok....
This mineral comes from Russia. When processed it forms highly toxic lead compounds....so it's basically killing everyone slowly.
On top of that it degrades quickly when exposed to light and heat....meaning that the solar cells are worthless after a few months of use. They create disposable solar cells.

No kidding. I have been saying that for years. We don't buy anything made in china.

China buys coal from any number of countries. They also are producing more themselves.

India has opened or will re-open 100 coal mines.

If CO2 is a threat (it isn't) then CO2 produced by China, India, and Pakistan would impact the world climate as much as our CO2.

That is interesting....
Especially if (and it's a mighty big "if") they can mass produce it to work well outside of the laboratory. Lots of things work in the lab but can't be mass produced or work in the field.

Pakistan isn’t building anything, they’re bankrupt. As for India.

India aims to cut power output from at least 81 coal-fired plants over 4 years

India plans to reduce power generation from least 81 coal-fired utilities over the next four years, the federal power ministry said in a letter, in an effort to replace expensive thermal generation with cheaper green energy sources.

India wants their power generation to come from 50% renewables in 7 years. Build new coal plants in huge numbers you say? Hmmm

India hasn't got enough energy as it is. They can "plan" all they want. It won't happen.

Watch what they do. Not what they say.

As of Jan of this year, India announced a 2.3 billion dollar program to promote green hydrogen. In August of last year, they passed an energy conservation bill to reduce emissions and greenhouse gases. India is currently the fourth largest producer of renewable energy in the world. They've invested over 20 billion from 2020 to 2022, in renewable energy. That's a lot of "doing."

And it's still no where good enough due to a basic lack of sanitation and clean water.

They have a robust economy....from pharmaceuticals to steel to agricultural products.

The Saudis manufacture highly efficient solar panels and are heavily in to green hydrogen. Of course they have been involved in research since 1980.
