Perovskite Tandem Solar Cells: A Path to Higher Efficiency Limits

Quick fact

Perovskite-silicon tandems have already reached over 30% efficiency in the lab, surpassing the ~29% practical limit of silicon-only cells.

Why this is interesting

Solar panels today capture only a fraction of the sun's energy. What if we could stack two cells, each tuned to a different color, to nearly double that limit?
