Recently, the piezoelectric nanogenerators(PENGs) based on flexible substrates have attracted considerable interest for the energy harvesting systems. In this study, the hybrid structure of zinc oxide(ZnO) nanorods layer and organic-inorganic lead halide perovskite-polymer composites were employed to fabricate the nanogenerators. The ZnO nanorods growed on flexible ITO substrate by hydrothermal method. A piezoelectric formamidinium lead halide perovskite(FAPbBr3) nanoparticles were synthesized with cubic perovskite structure. The nanogenerators based on the hybrid structure of ZnO nanorods and FAPbBr3-polymer composites were prepared to evaluate the piezoelectric output voltage and current density. As a result, enough piezoelectric output was available for use in electronic devices and smart sensors. |
