Tiny pinholes can lead to device failure in perovskite solar cells

Researchers in the United States have found microscopic pinholes in perovskites are responsible for the breakdown of such solar cells when under reverse bias conditions. They say the findings urge scientists and engineers to should prioritize the production of pinhole-free films to make perovskites more robust and stable.A microscopic weak spot can lead to device failure in perovskite solar cells, according to new research. A team of scientists …
