High-performance hybrid organic-inorganic perovskite nanoparticles based piezoelectric energy harvester

2016 
The present study provides a new facile route for hybrid piezoelectric nanogenerator based on a composite of piezoelectric formamidinium lead halide perovskite (FAPbBr3) nanoparticles and polydimethylsiloxane (PDMS) polymer. The piezoelectric device exhibits high performance with a maximum recordable output voltage of 8.5 V and current density of 3.8 & #x00B5;Acm-2 under periodical vertical compression and release operation. The alternating energy generated from nanogenerator is used to charge a capacitor through a bridge rectifier. This result innovatively expands the feasibility of organic-inorganic lead halide perovskite materials in the application of both piezoelectric and photovoltaic hybrid devices for energy harvesting.
