Band-Like Charge Transport in Cs2AgBiBr6 and Mixed Antimony-Bismuth Cs2AgBi1- xSbxBr6 Halide Double Perovskites
Abstract
<p>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 charges in Cs<sub>2</sub>AgBiBr<sub>6</sub> and in mixed antimony-bismuth Cs<sub>2</sub>AgBi<sub>1-x</sub>Sb<sub>x</sub>Br<sub>6</sub>, in which the band gap is tunable from 2.0 to 1.6 eV. Using temperature-dependent time-resolved microwave conductivity techniques, we find that the mobility is proportional to T<sup>-p</sup> (with p ≈ 1.5). Importantly, this indicates that phonon scattering is the dominant scattering mechanism determining the charge carrier mobility in these HDPs similar to the state-of-the-art lead-based perovskites. Finally, we show that wet chemical processing of Cs<sub>2</sub>AgBi<sub>1-x</sub>Sb<sub>x</sub>Br<sub>6</sub> powders is a successful route to prepare thin films of these materials, which paves the way toward photovoltaic devices based on nontoxic HDPs with tunable band gaps.</p>
