Abstract:

Triboelectric Nanogenerators (TENGs) represent a rapidly advancing technology for harvesting mechanical energy and converting it into usable electrical power. Their integration into wearable electronics and self-powered sensing devices has driven interest in optimizing their performance through advanced materials. This study explores the effect of incorporating Yttrium-Doped Cerium Sulphide (Y₂CeS₅) nanoparticles into Polyvinyl Alcohol (PVA) matrices at varying concentrations (0-4%) to enhance the triboelectric output. A systematic characterization approach was employed to investigate structural, morphological, and chemical features of the resulting nanocomposites, using Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Fourier-Transform Infrared spectroscopy (FTIR), and Energy-Dispersive X-ray spectroscopy (EDX). SEM analysis revealed uniform nanoparticle dispersion within the polymer matrix, indicating effective mitigation of agglomeration and improved interfacial contact-key factors for charge enhancement. XRD results demonstrated minor yet significant changes in crystallinity, suggesting the evolution of structural phases. FTIR spectra affirm the formation of interfacial bonds and functional group interactions between nanoparticles and polymer chains, while EDX verifies successful elemental incorporation and composite homogeneity. Electrical performance analysis indicated a direct correlation between nanoparticle concentration and output voltage, with the highest loading yielding markedly improved power generation. The generated voltage was sufficient to illuminate a series of LEDs, establishing the practical viability of composite-based TENGs. These findings offer critical insights into how nanoparticle integration influences material properties and energy output. The study presents a promising pathway for engineering high-performance TENGs, contributing to advancing efficient, sustainable, and scalable energy harvesting technologies.
