| Summary: | Abstract This study highlights a purpose-driven design and optimization of a C2N-based solar cell structure using the SCAPS-1D solar cell simulator. We investigate the performance characteristics of an ITO/MZO/C2N/CZT heterojunction stack, focusing on optimizing the Magnesium Zinc Oxide (MZO) Electron Transport Layer (ETL), the C2N absorber, and the CZT Hole Transport Layer/Back Surface Field (HTL/BSF). By systematically varying critical parameters such as ETL thickness, absorber thickness, and doping densities, along with interface characteristics and operating temperature, we engineer a device that achieves a peak simulated power conversion efficiency (PCE) of 32.20%. The optimized configuration yields impressive performance metrics, including Voc = 1.605 V, Jsc = 22.927 mA/cm², and FF = 87.48%. These results highlight the significant impact of meticulous layer engineering, especially with regard to the ETL and BSF, on achieving ultra-high efficiencies in C2N photovoltaics. |
