Charge Carriers in Planar and Meso-Structured Organic-Inorganic Perovskites
Abstract
<p>Efficient solar cells have been obtained using thin films of solution-processed organic-inorganic perovskites. However, there remains limited knowledge about the relationship between preparation route and optoelectronic properties. We use complementary time-resolved microwave conductivity (TRMC) and photoluminescence (PL) measurements to investigate the charge carrier dynamics in thin planar films of CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3-x</sub>Cl<sub>x</sub>, CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub>, and their meso-structured analogues. High mobilities close to 30 cm<sup>2</sup>/(V s) and microsecond-long lifetimes are found in thin films of CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3-x</sub>Cl<sub>x</sub>, compared to lifetimes of only a few hundred nanoseconds in CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> and meso-structured perovskites. We describe our TRMC and PL experiments with a global kinetic model, using one set of kinetic parameters characteristic for each sample. We find that the trap density is less than 5 × 10<sup>14</sup> cm<sup>-3</sup> in CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3-x</sub>Cl<sub>x</sub>, 6 × 10<sup>16</sup> cm<sup>-3</sup> in the CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> thin film and ca. 10<sup>15</sup> cm<sup>-3</sup> in both meso-structured perovskites. Furthermore, our results imply that band-to-band recombination is enhanced by the presence of dark carriers resulting from unintentional doping of the perovskites. Finally, our general approach to determine concentrations of trap states and dark carriers is also highly relevant to other semiconductor materials.</p>
