Abstract : Solar energy plays a pivotal role in the global search for sustainable and renewable energy sources. Among the wide range of solar technologies, solar cells stand out as key components in harnessing sunlight and converting it into electricity. The continual evolution of solar cell technologies has propelled the quest for efficient and cost-effective solutions, and Perovskite solar cells(PSC) have emerged promising in this field. Here, we conducted a thorough investigation using SILAR (Successive Ionic Layer Adsorption and Reaction) deposition to create Aluminum-doped Zinc Oxide (AZO) films at 2%, 4%, and 6% doping concentrations. UV-Visible Spectroscopy was used to carefully characterize these films, which gave us insight into their optical characteristics and comprehension of how they behaved at various doping concentrations. We carried out thorough identifications to obtain a comparative analysis of these AZO films as Electron Transport Layer (ETL) materials within Perovskite solar cells using the 1-D OghmaNano solar cell modelling tool. The choice of ETL material is important as it significantly impacts the efficiency, stability, and scalability of solar cells. Our work was centred on methodically examining how these AZO films, when used as ETLs, affect overall device efficiency. In order to achieve this, we carefully adjusted the ETL, HTL, and Active Perovskite layer thicknesses. We were able to determine optimal layer thicknesses for achieving the best possible device performance as a result. This work systematically investigates the impact of these materials as ETLs on device efficiency.
