Next-generation solar cells reach 24% efficiency with semiconductors using UV and visible parts of light, while perovskite absorbing near-infrared

University of Cologne at Tech Xplore reports a German research team has developed a tandem solar cell that reaches 24 percent efficiency—measured according to the fraction of photons converted into electricity (i.e., electrons). This sets a new world record as the highest efficiency achieved so far with this combination of organic and perovskite-based absorbers. The…
