Perovskite solar cells represent the fastest-developing photovoltaic technology to date, with a power-conversion efficiency (PCE) that has skyrocketed from 3.8% to 26.7% in the last 15 years. To further boost PCE, tandem architectures have been created that combine a wide-bandgap perovskite top cell with a narrow-bandgap bottom cell.
