Spray-On Solar Material Holds Promise

LAKE WALES, Florida—Photovoltaic (PV) materials that can be sprayed on like paint have been explored before, but researchers at the University of Virginia and Cornell University say they are on the trail of a PV that can be commercialized within the next few years. Professor Joshua Choi at the University of Virginia, collaborating with scientists from Cornell University’s High Energy Synchrotron Source, has been working on self-assembling metal halide perovskite thin film solar cells for several years. They were first discovered in 2009, but according to Choi it has taken just a single year for his group to develop a formulation the rivals silicon, giving the group hope that commercialization will be possible soon. Metal halide perovskites have already been used in lasers, photo detectors, transistors and light emitting diodes (LEDs), but Choi thinks their biggest contribu...
