Perovskite-organic tandem solar cell reaches a certified 27.82% efficiency
An October 2 science roundup says a champion cell reached 28.20% and retained 90% of its efficiency after 700 hours of maximum-power-point tracking.
TLDR
An October 2 science roundup highlights a perovskite-organic tandem solar cell with certified 27.82% efficiency. It says an additive made crystallization more uniform and suppressed light-induced halide segregation. A champion cell reached 28.20% and retained 90% of its efficiency after 700 hours of maximum-power-point tracking. The roundup cautions that one small cell cannot establish module yield or decades of outdoor life.
