Recently, halide double perovskites (HDPs), such as Cs<sub>2</sub>AgBiBr<sub>6</sub>, have been reported as promising nontoxic alternatives to lead halide perovskites. However, it remains unclear whether the charge-transport properties of these materials are as favorable as for lead-based perovskites. In this work, we study the mobilities of...

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...

Tailoring the physical properties of hybrid lead metal halide APbX<sub>3</sub> perovskites by means of compositional engineering is one of the key factors contributing to the development of highly efficient and stable perovskite solar cells. While the beneficial effects of partial ionic replacement at the A- and X-sites are largely...

In view of its band gap of 2.2 eV and its stability, methylammonium lead bromide (MAPbBr<sub>3</sub>) is a possible candidate to serve as a light absorber in a subcell of a multijunction solar cell. Using complementary temperature-dependent time-resolved microwave conductance (TRMC) and photoluminescence (TRPL) measurements, we demonstrate...
