Hybrid lead perovskites containing a mixture of organic and inorganic cations and anions have lead to solar cell devices with better performance and stability than their single halide analogs. Here, 207Pb solid-state nuclear magnetic resonance and single particle photoluminescence spectroscopies show that the structure and composition of mixed-halide and—likely—other hybrid lead perovskites is much more complex than previously thought and is highly dependent on their synthesis. While a majority of reports in the area focus on the construction of photovoltaic devices, this perspective focuses instead on achieving a better understanding of the fundamental chemistry and photophysics of these materials, as this will aid not only in constructing improved devices, but also in generating new uses for these unique materials.
