The global demand for renewable energy has spurred extensive research into improving the efficiency of solar cells. One promising approach is the integration of nanocomposite materials, such as cadmium sulphide (CdS) and polyvinyl alcohol (PVA), which can enhance the performance of photovoltaic devices. This study presents an in-depth analysis of the structural characterization of CdS-PVA nanocomposites and their potential application in enhancing solar cell efficiency. We employed various characterization techniques, including X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) to explore the structural, thermal, and chemical properties of these nanocomposites. Our results reveal that the incorporation of CdS nanoparticles into the PVA matrix significantly influences the structural, optical, and thermal properties, leading to improved photovoltaic performance. This research investigates the influence of CdS nanoparticles on the dielectric and physical properties of PVA-based nanocomposites for potential enhancement in solar cell efficiency. By systematically varying the CdS concentration (5%, 10%, and 20% w/w), we comprehensively characterised the structural, optical, and electrical properties of the nanocomposites. FTIR analysis revealed interactions between CdS and PVA, affecting the composite's molecular structure. Dielectric studies explored the frequency-dependent behaviour of dielectric permittivity, loss, and AC conductivity, elucidating the role of CdS in enhancing charge carrier mobility. The correlation between structural, optical, and dielectric properties was established to understand their impact on solar cell performance. The optimised CdS-PVA nanocomposite exhibited superior dielectric properties, suggesting its potential as an efficient charge transport layer or anti-reflective coating in solar cells. Further research will focus on incorporating this nanocomposite into solar cell devices to validate its efficiency enhancement capabilities.
