Thermal and environmental stability of metal halide perovskite solar cells remains a major barrier to their commercialization. The industry standard transparent electrode, ITO, has good optoelectronic properties and high stability. We introduce a robust buffer layer by solution-processing AZO nanoparticles, enabling a sputtered amorphous ITO layer without damaging the underlying device. We make both semitransparent cells (12.3%) and mechanically stacked tandems (12.3% + 5.7% = 18.0%) using…
