Charge Accumulation, Recombination, and Their Associated Time Scale in Efficient (GUA)(x)(MA)(1-x)PbI3-Based Perovskite Solar Cells

Shaik Mohammed Zakeeruddin, Pankaj Kumar Yadav, Daniel Prochowicz, Mohammad Mahdi Tavakoli, Anwar Qasem M Alanazi

Here, we study the influence of guanidinium (GUA) ions on the open-circuit voltage (V-oc) in the (GUA)(x)(MA)(1-x)PbI3 based perovskite solar cells. We demonstrate that incorporation of GUA forms electronic and ionic accumulation regions at the interface o ...
