Abstract

This paper investigates the utilization of RbGeBr3 as an absorbing layer in two types of perovskite solar cells. The investigation involves systematic adjustments in the thicknesses of both the RbGeBr3 as absorber layer and the electron transfer layer. The Poisson, continuity, and transport equations are solved using the finite element method. Gold was chosen as the electrode's metal contact. Furthermore, the study investigates the effect of temperature fluctuations on the efficiency of these systems. The FTO/ITO/RbGeBr3/PEDOT: PSS/Au configuration has the highest power conversion efficiency (11.37%), with a short-circuit current of 14.472 mA/cm² and an open-circuit voltage of 0.96 V. Furthermore, an alternative structure, FTO/TiO2/RbGeBr3/CuSCN/Au, is investigated, resulting in power conversion efficiencies of 10.58%. These findings have important implications for the development of more advanced and efficient perovskite solar cells with mineral perovskite layers.
