Excellent Carrier Transport Property of Hybrid Perovskites Sustained under High Pressures
Source abstract
Abstract
High pressure treatment has become an effective way to tune the optical properties of halide perovskites. However, how compression can affect the carrier transport in perovskites remains unknown. Herein, by combining time-resolved imaging microscopy with a diamond anvil cell, we report in situ measurement of carrier transport in CH3NH3PbI3 perovskite microcrystals (MCs) under high pressure. From ambient pressure to 5.7 GPa, the pressure induces a phase transition at 0.3–0.4 GPa and an isostructural phase transition at about 3 GPa. The carrier diffusivity is found to increase by at least 30% from ∼1.82 cm2 s–1 at ambient pressure to 2.32–2.90 cm2 s–1 at 0.4–5.7 GPa, leading to long carrier diffusion lengths of 5–8 μm. This result indicates that the perovskites can sustain excellent carrier transport properties under high pressure and thus enhances the potential of compression for optimizing the optoelectronic performance of perovskite materials.
