Here, we study the influence of guanidinium (GUA) ions on the open-circuit voltage (<i>V</i> <sub>oc</sub>) in the (GUA) <i><sub>x</sub></i> (MA)<sub>1-<i>x</i></sub> PbI<sub>3</sub> based perovskite solar cells. We demonstrate that incorporation of GUA forms electronic and ionic accumulation regions at the interface of the electron transporting layer and perovskite absorber layer. Our electrochemical impedance spectroscopy results prove that the formed accumulation region is associated with the ...[more]
