Oxford PV, a spin-off from the University of Oxford, says it’s achieved the world record for the most efficient solar panel.
In collaboration with Germany’s Fraunhofer Institute for Solar Energy Systems, the company says its solar panel achieved 25% conversion efficiency – the percentage of solar energy shining on a panel converted into electricity. That’s a big deal compared to the more typical 16-24% in commercial solar panels.
You seem to know about the topic. Does the official release help? Seems to have some differences in information compared to the article.

From what i can gather this is “tandom cell” offering a higher theoretical maximum compared to silicon based, whatever that even means.
