Preventing lead leakage in perovskite cells

A U.S. research group has used a lead-absorbing material to coat the front and rear of a perovskite solar cell stack. The researchers claim the films captured 96% of lead leakage when the cells were damaged.While researchers around the globe try to develop lead-free perovskite solar cells, a research team from the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) has come up with a technique to dramatically reduce lead leakage in such devices. The NREL team said the innovation is vital given the potential threat to public health if lead leaks from building-integrated PV ...
