Abstract
Perovskite solar cells have garnered significant attention from solar cell researchers due to their potential for achieving high efficiency,
primarily attributed to their exceptional Electron Transport layer (ETL). One of the key elements of perovskite solar cells for
transporting electrons to generate current is the ETL material. Moreover, there is a promising avenue for enhancing stability and
reducing fabrication costs by substituting the transport layer. In this study, TiO2 and SnO2 were used as ETL materials in the architecture
of perovskite solar cells for a comparative analysis between two devices featuring distinct structures: TiO2/CH3NH3PbI 3 /Spiro-
OMeTAD and SnO 2/CH3NH3PbI 3/Spiro-OMeTAD. To evaluate the performance of each electron transport layer (ETL), the SCAPS
1D tool was employed. The investigation involved varying the thickness of the electron transport layers, interface defect density and
working temperature, allowing for a comprehensive assessment of key parameters such as voltage at open circuit (Voc), short circuit
current density (Jsc), fill factor (FF), and overall efficiency (PCE%). Remarkably, when employing SnO2 as the ETL, the achieved
efficiency stands at 10.10 %. In contrast, utilizing TiO2 as the ETL yields a slightly higher efficiency of 12.84%. These findings
underline the nuanced influence of transport layer materials on the overall performance of perovskite solar cells
