Abstract

All inorganic perovskite materials have drawn extensive attention, owing to their outstanding performance, facile solution-processed method, and potential applications in optoelectronic devices. However, uncontrollable morphology, high defect density, and instability of perovskites prepared via solution-processed method are the main challenges for their large-scale production and commercialization. Herein, we prepared large-scale ${\rm{CsPbB}}{{\rm{r}}_3}$ microwire arrays with highly ordered morphology and high crystalline quality by a template-assisted method. The photodetectors based on ${\rm{CsPbB}}{{\rm{r}}_3}$ microwire arrays exhibited remarkable on/off photocurrent ratio of ${9.02} \times {{1}}{{{0}}^3}$, high detectivity of ${1.59} \times {{1}}{{{0}}^{13}}$ Jones, high responsivity of 4.55 A/W, and fast response speed of 4.9/3 ms. More importantly, the photocurrent of the photodetectors hardly changed in air after being stored for two months, indicating remarkable stability. This study demonstrates that ${\rm{CsPbB}}{{\rm{r}}_3}$ microwire arrays provide the possibility for preparing large-scale and high-performance optoelectronic devices.
