Coupling with perovskite solar cell holds potential for cleaner cars, home power sources and more. Researchers have wired 4 perovskite solar cells in series to enhance the voltage and directly photo-charged lithium batteries with 7.8% efficiency – the most efficient reported to date, the researchers believe.
“Others have used polymer solar cells to charge lithium batteries, but not with this efficiency.” Perovskite solar cells have active materials with a crystalline structure identical to the mineral perovskite and are considered a promising new design for capturing solar energy. Compared to silicon-based cells, they convert a broader spectrum of sunlight into electricity..
Dai’s lab made multilayer solar cells, which increases their energy density, performance and stability...
