Perovskite solar panels: an expert guide [2024]
However, by layering perovskite on top of silicon (called ''tandem solar cells''), this combines the best of both materials. Perovskite is better at absorbing a part of the light spectrum that silicon can''t handle well, while silicon is more stable. The efficiency of this combination has recently reached a staggering 34.6%.
