A strategy to create more efficient narrow bandgap (NBG) perovskite films for tandem solar cells

All-perovskite tandem solar cells, solar cells comprised of stacked wide-bandgap (WBG) and narrow-bandgap (NBG) perovskites, could be particularly promising energy solutions. Compared to other existing photovoltaic systems, these cells could achieve good energy-efficiencies while significantly lowering fabrication costs.
