This study investigates the properties of nanocomposites and their impact on improving the performance of solar photovoltaic (PV) cells through the deposition of nano Titanium Dioxide (TiO2) sol onto a glass substrate. In addition to the coating process, nano Aluminum oxide Al2O3 is added, which alter the surface properties such as, thickness and roughness, of the substrate medium. When exposed to a temperature of 450°C, the crystallinity of the TiO2 transforms from amorphous to anatase. Three techniques are used for this research investigation, they are Field emission scanning electron microscopy (FESEM) analysis for microstructural analysis, Energy-dispersive X-ray spectroscopy (EDAX) for verifying the presence of various elements and Ultraviolet-visible (UV-VIS) spectroscopy is used to visualize the optical properties of the coarse surface characterized by spikes. An absorption rate of 1.36% is observed, with reduction in reflection from 14% to 10%. The water contact angle is measured to analyze the surface wettability. The results reveal a 15% efficiency in the I-V characteristics and the surface exhibits hydrophilic nature.
