China’s CAS Sets World Record 15.45% Efficiency for Kesterite Solar Cell

Scientists at the Chinese Academy of Sciences built a kesterite solar cell that achieved a world record efficiency of 15.45%. The team solved a metal ion migration problem using a new lithium tin sulfide layer that stabilizes the cell and reduces defects. The certified efficiency of 15.04% moves cheaper, abundant-material solar cells closer to commercial reality.
