Abstract
Incorporating 2.5% Cs in FA<sub>0.8</sub>MA<sub>0.2</sub>Sn<sub>0.5</sub>Pb<sub>0.5</sub>I<sub>3</sub> improves the photo-stability of the low-bandgap perovskite solar cells. The champion device with power conversion efficiency of 18.9% maintain 92% of its initial efficiency after 120 min MPP tracking.
