I think the idea is that it’s the same amount of light is being used but the actual expensive part of the solar cell is cheaper and designed to take the increased heat. So the same size “solar unit” on the roof collecting the same amount of light and generating the same amount of energy but cheaper overall. At least that was my take. Correct me if I’m wrong.
Yeah, a similar amount for less money could be feasible. I guess. Not sure how cheap the sanding of the lens structure is though

What was the stuff like this of 15 years ago ?
Honestly solar panels and electric cars. I know those existed over 15 years ago, but they weren't serious market options until like 5 or so years ago.

Solar energy experts in Germany are putting sun-catching cells under the magnifying glass with astounding results, according to multiple reports.
The Fraunhofer Institute for Solar Energy Systems team is perfecting the use of lenses to concentrate sunlight onto solar panels, reducing size and costs while increasing performance, Interesting Engineering and PV Magazine reported.
The "technology has the potential to contribute to the energy transition, facilitating the shift toward more sustainable and renewable energy sources by combining minimal carbon footprint and energy demand with low levelized cost of electricity," the researchers wrote in a study published by the IEEE Journal of Photovoltaics.
The sun-catcher is called a micro-concentrating photovoltaic, or CPV, cell. The lens makes it different from standard solar panels that convert sunlight to energy with average efficiency rates around 20%, per MarketWatch. Fraunhofer's improved CPV cell has an astounding 36% rate in ideal conditions and is made with lower-cost parts. It cuts semiconductor materials "by a factor of 1,300 and reduces module areas by 30% compared to current state-of-the-art CPV systems," per IE.
Wait for something fucking idiotic like:
"U.S. government to implement 5,000% tax on new solar technology...."

OK, take that Fresnel lens that you were using to melt pennies and then focus it on a PV cell that is also made of metal. What might be the expected response? The science in this case is making PV cells that can handle the intense heat.
That makes sense. If I understood everyone clearly, it's not the idea to use a fresnel that's new here, it's the fact that we just haven't yet had anything capable of withstanding those temperatures and still allowing for the piezoelectric effect to happen.

If I had a penny for every time I heard about new advancements about to revolutionise solar panel technology, I'd have glazed the bloody Sahara with them by now.

More expensive and less efficient.

First known electric car was built in 1837. Yes, 1837, not 1937. In 1910's and 1920's there were tens of thousands electric cars in USA and Europe. So electric cars has been here for a long time right now.
First (known) solar panel was built in 1954.

Would the cost chart of PV cells look something like this?

Yes, hence the name motor vehicle. His point was modern implementations of EVs and solar panels. 10-20 years is very common for transition to production. It takes time to scale up manufacturing and that's only after the manufacturers have actually decided/agreed to take on the risk of a new product line. Lithium ion batteries were invented in the 80s, but didn't see broad deployment until the 00s.

Solar panels are already quite cheap. What we need is much cheaper grid forming inverters so we can stop destabilizing the grid with solar.

I like the understatement. Shame they spoiled it with the "game changing" claim at the beginning.

If the cost of panels drops significantly, there would be more capital available to spend on inverters, even if they stay at the current prices, still decreasing the cost of deployment. But yes.

Wait for something fucking idiotic like:
"U.S. government to implement 5,000% tax on new solar technology...."
"also, revenue from new tax will be used to build new coal mines staffed by concentration camp inmates 1"

Grid forming will just mean the keep running the house when the power goes off, it's not safe for them to be pushing power when it's disappeared, that has been set by regulation in many countries.

I suspect that the lens makes the whole solar assembly more directional and the Sun moves in the sky.
Commercial solar panels often move with the sun, too

Even crazier that it's a logarithmic graph.

Solar is too woke and Marxist for the current US government.

The only thing slowing down the transition from fossil fuels to renewables is the same impediment it has always been: oil money protecting itself.
