I’ll be honest, this article has me really confused on what the actual achievement was. They say they got a 25 % peroveskite/si cell, but that they already manufacture 28% efficient peroveskite/si cells at scale.

The current world record for peroveskite/ si cells is HZB’s 32.5% record, and the world record record for any cell material is FhG-ISE’s 47.6% four+ junction cells, so i’m not sure what this record was in.
