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

Researchers from the University of Washington and the FOM Institute for Atomic and Molecular Physics in the Netherlands have developed a way to map strain in lead halide perovskite solar cells. Their approach shows that misorientation between microscopic perovskite crystals is the primary contributor to the buildup of strain within the solar cell, which creates small-scale defects in the grain structure, interrupts the transport of electrons within the solar cell, and ultimately leads to heat loss through a process known as non-radiative recombination.
