Research Boosts Stability of Perovskites, Helps Silicon Solar Cells
A change in chemical composition enabled scientists to boost the longevity and efficiency of a perovskite solar cell. The new formula enabled the solar cell to resist a stability problem that has so far thwarted the commercialization of perovskites. The problem is known as light-induced phase-segregation, which occurs when the alloys that make up the solar cells break down under exposure to continuous light.

Shedding New Light on the Charging of Lithium-ion Batteries
Exposing cathodes to light decreases charge time by a factor of two in lithium-ion batteries. Researchers have reported a new mechanism to speed up the charging of lithium-ion batteries for electric vehicles. Simply exposing the cathode to a beam of concentrated light -- for example, the white light from a xenon lamp -- lowers the battery charging time by a remarkable factor of two or more. If commercialized, such technology could be a game changer for electric vehicles.
