Effect of Zinc Oxide—Aluminium Oxide Mechanical Blends for Boosting the Polycrystalline Silicon Solar Cell Performance Through Antireflection Properties

In the current context, there is a great desire to develop renewable energy sources as a power source. In order to improve the power conversion efficiency (PCE) of silicon solar cells, several studies are being undertaken in this area. This investigation focuses on preparing ZnO-Al2O3 blend as an antireflective coating (ARC) for improving the efficiency of polycrystalline silicon power conversion. The sol—gel method was employed to synthesis ZnO-Al2O3 blend which is produced by mixing zinc oxide with aluminium oxide. The spin coating process was used to deposit single to four layers of ZnO-Al2O3 blend on a silicon solar substrate. The thickness of ZnO-Al2O3coating obtained was measured with the help of atomic force microscopy (i.e.40 nm).The effect of zinc oxide and aluminium oxide coating on electrical, structural and optical characteristics of coated polycrystalline silicon solar cells, as well as cell temperature is investigated. A layer deposition of a single to multiple layers on a silicon solar cell was identified by an increase in layer thickness. At a low cell temperature (40 °C), the triple layer(LIII)deposition attained a maximum absorbance of 92
