dc.description.abstractEnergy is an essential component of our daily life, and it is hard to imagine a day without it. The photovoltaic cell produces voltage or electric current by utilizing sunlight through the photovoltaic effect. While silicon photovoltaic (PV) cells grown on wafers have the disadvantage of being expensive and low in efficiency, thin-film (PV) cells technology is utilized for efficient energy production. Photovoltaic devices extensively utilize Aluminium-doped Zinc oxide thin films (AZO) due to their functionality of light transmission. This study investigated the thin film deposition on soda lime, borosilicate, and simple looking glass substrates using the Aluminium doped ZnO technique and radio frequency magnetron (RF) sputtering method, with a focus on sputtering power (W) on the optical properties of the films and structural analysis of the film. X-ray diffraction abbreviated as XRD and an Ultraviolet visible spectroscopy have been used to explore and analyze the Aluminium doped zinc oxide thin films. The observed diffraction peaks in all the AZO thin films were found to exhibit a hexagonal wurtzite crystal structure, with a predominant growth orientation forward the (0 0 2) plane and the c-axis perpendicular to the substrate, as evaluated through structural analysis. Transmittance measurements were conducted to gain the desired optical properties of thin films. It was discovered that film thickness had a significant impact on the optical band gap, with the band gap of samples 1, 2, and 3 increasing with the sputtering power (W). The optical band gap of aluminium doped zinc oxide increased with increasing sputtering power in the range of 30 to 500 W. The increase in sputtering power resulted in an increase in film thickness, leading to higher optical transparency and a widening of the band gap
