Altogether, these qualities make perovskites promising active layers not only in photovoltaics (technologies that convert light into electricity), but also in other types of electronic devices that respond to or control light including light-emitting diodes (LEDs), detectors, and lasers.

But “although perovskites offer great potential for greatly expanding solar power, they have yet to be commercialized because their reliable synthesis and long-term stability has long challenged scientists,” said Carolin Sutter-Fella, a scientist at the Molecular Foundry, a nanoscience user facility at Lawrence Berkeley National Laboratory (Berkeley Lab). “Now, a path to perfect perovskites may soon be within reach.”  Read more….
