Researchers at Martin Luther University Halle-Wittenberg (MLU) have discovered a new method to increase the efficiency of solar cells by a factor of 1,000. The team of scientists achieved this breakthrough by creating crystalline layers of barium titanate, strontium titanate, and calcium titanate, which were alternately placed on top of one another in a lattice structure.

Their findings, which could revolutionize the solar energy industry, were recently published in the journal Science Advances.

It's not a measure of efficiency per se, but efficiency is a limiting factor:

In order for a solar panel to put out 1000x more power, the baseline you're comparing it to must be at most 0.1% efficient, because otherwise the new thing would have greater than 100% efficiency and that isn't possible.

And that's a purely thermodynamic argument. The actual limit for solar efficiency is likely less.
