GoKawiilGroningen researchers slow hot-electron cooling 1,000x in tin perovskite solar cells
Researchers at the University of Groningen, led by Maria Antonietta Loi with Koster and PhD student Tim Faber, found that tin-based perovskite solar cells keep 'hot electrons' energetic for nanoseconds instead of picoseconds, a thousandfold slowdown in heat loss. Computer simulations of the material's quantum behavior matched the lab results and revealed a double-action mechanism behind the effect, linked to the material's unusually low electron mass.
