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?
