Organic–inorganic lead halide perovskite materials are emerging as promising piezoelectric materials due to a high piezoelectric coefficient. In this study, formamidinium lead halide perovskite(FAPbBr3) nanocrystals were successfully synthesized at room temperature, and have different size and thickness depends on oleylamine contents in the synthesis. For the application of FAPbBr3 nanocrystals in piezoelectric nanogenerators, FAPbBr3-PDMS composites were prepared on the ITO/glass and ITO/film substrate. Piezoelectric nanogenerators(PENGs) based on the FAPbBr3-PDMS composite structure were successfully fabricated, and have a maximum piezoelectric output voltage and current density. The effect of the shape on the performance for the PENG were addressed in terms of the piezoelectric properties. We expect that the PENGs based on the FAPbBr3-PDMS composite would be a good candidate for the application in electronic device, energy harvesters, and sensors. |
