AB - The integration of advanced functional materials into mechanical energy harvesting systems is essential for future energy solutions. The present work focuses on the synthesis of Cs2AgBiBr6 double perovskite using a modified antisolvent reprecipitation method and its incorporation into the Polyvinylidene fluoride (PVDF) polymer to enhance triboelectric performance using the solvent casting method. The nanocomposites, fabricated with variable Cs2AgBiBr6 concentration (0.0, 0.5, 1.0, 2.0 and 4.0 wt/wt%), were subjected to various structural, morphological and optical characterisations by employing various spectroscopic and microscopic techniques. The fabricated nanocomposite shows high stability and charge-holding capability, ensuring effective performance across diverse environmental conditions. Therefore, the prepared nanocomposites were utilised as an electroactive layer for the fabrication of Triboelectric nanogenerators (TENGs). The optimised double perovskite-polymer-based triboelectric nanogenerator (P-TENG) reveals a substantial enhancement in output performance. Notably, the device incorporating 4.0 wt/wt % exhibited a peak-to-peak output voltage and current of 352 V and 52 µA (under 5 Hz and 10 N conditions), than those of the pristine PVDF-based TENG device. Furthermore, the device demonstrated practical applicability by efficiently powering over 60 LEDs, charging different capacitors, and powering the digital watch. Overall, this research highlights the role of lead-free double perovskite-based triboelectric nanogenerators in advanced self-sustainable energy harvesting applications.
