After 40 Years of Searching, Scientists Identify The Key Flaw in Solar Panel Efficiency
https://www.sciencealert.com/scientists-identify-a-key-flaw-in-solar-panel-efficiency-after-40-years-of-searching

Excerpt:
A new study outlines a material defect in silicon used to produce solar cells that has previously gone undetected. It could be responsible for the 2 percent efficiency drop that solar cells can see in the first hours of use: Light Induced Degradation (LID).

Multiplied by the increasing number of panels installed at solar farms around the world, that drop equals a significant cost in gigawatts that non-renewable energy sources have to make up for.

In fact, the estimated loss in efficiency worldwide from LID is estimated to equate to more energy than can be generated by the UK's 15 nuclear power plants. The new discovery could help scientists make up some of that shortfall.

I told those guys to look for that!  [wink][wink]

This maybe is no different then the long line of other maybes over the last 40 years.

In the end it will be all about the money. Will the increase in power justify the cost of the new panels? As older panels age, probably yes, but otherwise...

And will it be necessary with the advent of newer designs and technologies? Double-sided panels, Perovskites, and clear panels are all starting to be used. Though none are fully vetted yet, each looks promising.

"In fact, the estimated loss in efficiency worldwide from LID is estimated to equate to more energy than can be generated by the UK's 15 nuclear power plants. The new discovery could help scientists make up some of that shortfall."

The energy production from the 15 UK nuclear power plants is about 336 TWh/year.
Worldwide energy production is about 25,000 TWh/year.

25336/25000 * 100% = 101.344%

Based on the numbers supplied. If they can solve the Light Induced Degradation problem, replaced all the installed solar capacity with the new technology. The global production will increase by only 1%.

Considering the labor and cost of replaced all the global installed solar capacity, would it be worth it?

Agree with you Rick.

In all the discussions about efficiency, COST efficiency is often overlooked.

When push comes to shove, it's all about the money. Always. Do the math.
