Abstract

In order to meet the ever-increasing call for alternative energy, a plethora of novel materials have been explored to harvest energies. Amongst them, organic-inorganic halide perovskites belong to a relatively new class of compounds. In this work, we have prepared FAPbBr(3) cubes via solution process and explored its candidature in energy harvesting. Piezoelectric nanogenerator (PNG) based on the composite of FAPbBr(3) and poly (vinylidene fluoride) (PVDF) showed noticeable output performance. To get benchmark level output response, concertation of perovskite was optimized in composites. PNG fabricated with 3.0 wt% FAPbBr(3) in PVDF exhibited an instantaneous output voltage of similar to 200 V and current of similar to 650nA. It also showed long cycle stability (10,000 cycles) and durability under robust conditions. Energy generated from the PNG was further utilized to charge a capacitor and light up commercial LEDs. As obtained results are of great importance and open the feasibility of novel smart device using this kind of perovskites.
