Double perovskites, comprising two different cations, are potential nontoxic alternatives to lead halide perovskites. Here, we characterized thin films and crystals of Cs<sub>2</sub>AgBiBr<sub>6</sub> by time-resolved microwave conductance (TRMC), which probes formation and decay of mobile charges upon pulsed irradiation. Optical excitation of films results in the formation of charges with a yield times mobility product, φΣμ > 1 cm<sup>2</sup>/Vs. On excitation of millimeter-sized crystals, the ...[more]
