摘要

To meet the growing demands for energy consumption, double perovskites (DP) have emerged as a promising green energy solution, offering substantial potential for applications in thermoelectric and optoelectronic devices. This study investigates novel hybrid perovskite solar cells (HPSCs) based on Rb2AlAgI6, using the SCAPS-1D simulator to analyze their performance. The cells incorporate C60 as the electron transport layer (ETL) and CBTS as the hole transport layer (HTL). Simulation results reveal that the ITO/C60/Rb2AlAgI6/CBTS heterostructure exhibits remarkable photoconversion efficiency. Furthermore, a detailed analysis explores the effects of key parameters, including Rb2AlAgI6 absorber thickness, ETL and HTL thicknesses, temperature, absorber defects, and resistance factors. The simulations indicate an optimal open-circuit voltage (Voc) of 1.13 V, short-circuit current density (Jsc) of 34.74 mA/cm², fill factor (FF) of 83.56%, and power conversion efficiency of 29.41%, aligning with previous research. This comprehensive study offers valuable insights into the factors influencing perovskite solar cell (PSC) performance and highlights promising pathways for future advancements in this technology.
