Perovskite photovoltaics achieved 26.1% lab efficiency in under a decade—surpassing silicon’s historical trajectory—due to tunable bandgaps and defect-tolerant crystal structures.
However, operational stability remains limited by ion migration under electric fields, moisture-induced lattice decomposition, and thermal phase segregation.
