New technique lets researchers map strain in next-gen solar cells

07/11/2019

Researchers have developed a way to map strain in lead halide perovskite solar cells without harming them. Their approach can image the grain structure of a perovskite solar cell, showing that misorientation between microscopic perovskite crystals is the primary contributor to the buildup of strain within the solar cell.
