What was the stuff like this of 15 years ago ?
More expensive and less efficient.

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.
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.

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.
"Has the potential to contribute...." Wow. Amazing.

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.
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.

How does concentrating the sunlight like this not start a fire? Or wouldn’t this at least cause panel electronics to overheat?
I would imagine they're not concentrating maximally. Just enough to increase efficiency.
-

The overwhelming majority of them don't, traditionnal rooftop installs don't either.

I wonder what kind of concentrating optics they use. Simple Fresnel lenses won't do, unless you closely follow the sunlight to stay in focus.

I'm not sure what to think about the Fraunhofer institute in general. They have made some nice discoveries/inventions in the past, such as audio compression algorithms and such. That is why i hyped them for a bit.
But they really disappointed me with their writings on solar panels in the past few years.
They said that the efficiency of solar panels today is too low to deploy them widely in practice, which is simply not true. They tried pushing Perovskite solar cells for no reason.
I'm not sure what to think about this article's idea. On one hand, adding lenses to solar parks makes them significantly more complicated and therefore expensive to build. Also, if the parks have complicated physical forms, they're more susceptible to wind, and that could damage them.
On the other hand, yes, adding lenses means you need fewer actual solar panels for the same amount of energy harvested.
I'll therefore put it in the category of inconclusive inventions, together with the idea of adding a motor to the solar panels so they can track the sun. That would also make the solar panels more efficient, but also more complicated and more prone to mechanical failure.
