Chinese researchers test perovskite solar panels 10 meters underwater

Scientists near Weizhou Island, publishing in the journal Joule, generated electricity from sunlight at a depth of about 33 feet using perovskite-based solar cells tuned to capture blue and green light that penetrates seawater. The two-hour simulated test produced 324 milliwatt-hours and reached a peak power conversion efficiency near 35 percent, according to the study led by Yunnan University's Wen-Hua Zhang.

Groningen 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.
