Figure 1 contains data for the limiting efficiency of a Shockley-Queisser tandem solar cell, with and without luminescence coupling included in simulations. Figure 2 contains decay data from transient absorption spectroscopy and photoluminescence quantum efficiency measurements for the halide perovskite thin film FA0.7Cs0.3Pb(I0.7Br0.3)3. It also contains absorption coefficient and (real) refractive index for both FA0.7Cs0.3Pb(I0.7Br0.3)3 and FAPb0.5Sn0.5I3 thin films, as measured by a combination of ellipsometry, photothermal deflection spectroscopy and Ubach tail fitting. Figure 3 contans the absorbance of FAPb0.5Sn0.5I3 in an idealised tandem stack with FA0.7Cs0.3Pb(I0.7Br0.3)3, the limiting efficiency of this stack as a function of thickness without and with luminescence coupling included in simulations, and the difference in power generated throughout the year without and with luminescence coupling for a typical spectral year on the Canada/USA border from these modelled solar cells. Figure 4 contains the limiting efficiency of the all-perovskite tandem as a function of charge trapping rate (for optimised thicknesses) with luminescence coupling, and a ratio of this result to a second simulation including luminescnece coupling. Figure 5 explores an experimental all-perovskite tandem solar cell. It contains the photoluminescence emission (relative to that at open-circuit voltage) of the high-bandgap sub-cell as a function of applied voltage when illuminated by a 405nm laser, the microscopic photoluminescence from a cross section of the tandem when excited by a 636nm laser, the photolumiescence from a cross section of this region when only the high-bandgap sub-cell is excited, and the time resolve photoluminescence of this emission.
