High-efficiency lead-free all-perovskite tandem solar cells achieving 28.22 % power conversion efficiency: A Cs2AgBi0.75Sb0.25Br6/FASnI3 heterostructure design
This research looks at how well an all-perovskite, lead-free tandem solar cell works. It has a wide-bandgap (1.8 eV) Cs2AgBi0.75Sb0.25Br6 top subcell and a narrow-bandgap (1.41 eV) FASnI3 bottom subcell. We show a very efficient device design by carefully adjusting the thicknesses of the absorber la...
