dc.description.abstract | We report the electrical properties of rubidium-incorporated methylammonium lead iodide ((Rb(x)MA(1-x))PbI3) films and the photovoltaic performance of (Rb(x)MA(1-x))PbI3 film-based p-i-n-type perovskite solar cells (PSCs). The incorporation of a small amount of Rb+ (x = 0.05) increases both the open circuit voltage (V-oc) and the short circuit photocurrent density (J(sc)) of the PSCs, leading to an improved power conversion efficiency (PCE). However, a high fraction of Rb+ incorporation (x = 0.1 and 0.2) decreases the J(sc) and thus the PCE, which is attributed to the phase segregation of the single tetragonal perovskite phase to a MA-rich tetragonal perovskite phase and a RbPbI3 orthorhombic phase at high Rb fractions. Conductive atomic force microscopic and admittance spectroscopic analyses reveal that the single-phase (Rb(0.05)MA(0.95))PbI3 film has a high electrical conductivity because of a reduced deep-level trap density. We also found that Rb substitution enhances the diode characteristics of the PSC, as evidenced by the reduced reverse saturation current (J(0)). The optimized (Rb(x)MA(1-x))PbI3 PSCs exhibited a PCE of 18.8% with negligible hysteresis in the photocurrent-voltage curve. The results from this work enhance the understanding of the effect of Rb incorporation into organic-inorganic hybrid hali | - |
