Efficient Piezoelectric Energy Harvesting from a Discrete Hybrid Bismuth Bromide Ferroelectric Templated by Phosphonium Cation
Abstract
<jats:title>Abstract</jats:title><jats:p>Bismuth containing hybrid molecular ferroelectrics are receiving tremendous attention in recent years owing to their stable and non‐toxic composition. However, these perovskite‐like structures are primarily limited to ammonium cations. Herein, we report a new phosphonium based discrete perovskite‐like hybrid ferroelectric with a formula [Me(Ph)<jats:sub>3</jats:sub>P]<jats:sub>3</jats:sub>[Bi<jats:sub>2</jats:sub>Br<jats:sub>9</jats:sub>] (<jats:bold>MTPBB</jats:bold>) and its mechanical energy harvesting capability. The Polarization‐Electric field (<jats:italic>P‐E</jats:italic>) measurements resulted in a well‐defined ferroelectric hysteresis loop with a remnant polarization value of 2.1 μC cm<jats:sup>−2</jats:sup>. Piezoresponse force microscopy experiments enabled visualization of the ferroelectric domain structure and evaluation of the piezoelectric strain coefficient (<jats:italic>d</jats:italic><jats:sub>33</jats:sub>) for an <jats:bold>MTPBB</jats:bold> single crystal and thin film sample. Furthermore, flexible devices incorporating <jats:bold>MTPBB</jats:bold> in polydimethylsiloxane (PDMS) matrix at various concentrations were fabricated and explored for their mechanical energy harvesting properties. The champion device with 20 wt % of <jats:bold>MTPBB</jats:bold> in PDMS rendered a maximum peak‐to‐peak open‐circuit voltage of 22.9 V and a maximum power density of 7 μW cm<jats:sup>−2</jats:sup> at an optimal load of 4 MΩ. Moreover, the potential of <jats:bold>MTPBB</jats:bold>‐based devices in low power electronics was demonstrated by storing the harvested energy in various electrolytic capacitors.</jats:p>
