Deciphering the effect of traps on electronic charge transport properties of methylammonium lead tribromide perovskite
Abstract
<jats:p>Halide perovskites have undergone remarkable developments as highly efficient optoelectronic materials for a variety of applications. Several studies indicated the critical role of defects on the performance of perovskite devices. However, the parameters of defects and their interplay with free charge carriers remain unclear. In this study, we explored the dynamics of free holes in methylammonium lead tribromide (MAPbBr<jats:sub>3</jats:sub>) single crystals using the time-of-flight (ToF) current spectroscopy. By combining ToF spectroscopy and Monte Carlo simulation, three energy states were detected in the bandgap of MAPbBr<jats:sub>3</jats:sub>. In addition, we found the trapping and detrapping rates of free holes ranging from a few microseconds to hundreds of microseconds. Contrary to previous studies, we revealed a strong detrapping activity of traps. We showed that these traps substantially affect the transport properties of MAPbBr<jats:sub>3</jats:sub>, including mobility and mobility-lifetime product. Our results provide an insight on charge transport properties of perovskite semiconductors.</jats:p>
