摘要：

Organic-inorganic lead halide perovskite materials have recently attracted much attention in the field of optoelectronic devices. Here, a hybrid piezoelectric nanogenerator based on a composite of piezoelectric formamidinium lead halide perovskite (FAPbBr(3)) nanoparticles and polydimethylsiloxane polymer is fabricated. Piezoresponse force spectroscopy measurements reveal that the FAPbBr(3) nanoparticles contain well-developed ferroelectric properties with high piezoelectric charge coefficient (d(33)) of 25 pmV(-1). The flexible device exhibits high performance with a maximum recordable piezoelectric output voltage of 8.5 V and current density of 3.8 mu A cm(-2) under periodically vertical compression and release operations. The alternating energy generated from nanogenerators can be used to charge a capacitor and light up a red light-emitting diode through a bridge rectifier. This result innovatively expands the feasibility of organic-inorganic lead halide perovskite materials for application in a wide variety of high-performance energy harvesting devices.
