Scientists make the world’s most efficient solar panel. German researchers have built the most efficient solar panel ever, turning 34.4% of sunlight into electricity. That’s way higher than ordinary rooftop panels, which usually convert between 20-23%. This is a research breakthrough, not something you can buy for your roof yet, but it shows how much better solar panels may still become.
