Enhanced performance and stability of low-bandgap mixed lead–tin halide perovskite photovoltaic solar cells and photodetectors via defect passivation with UiO-66-NH2 metal–organic frameworks and interfacial engineering

The incorporation of the UiO-66-NH 2 metal–organic frameworks as the processing additive into mixed lead–tin halide perovskites can effectively passivate the defects, enabling the photovoltaic devices to exhibit high performance and good stability.
