Polarons correspond to composite quasiparticles that are formed due to the local polarization of a crystal lattice caused by the presence of charged particles. They stand apart from defects , showcasing superior mobility characteristics in crystal structures . In perovskite structures, Jahn-Teller type distortions localized around the transition metal sites and the formation of so-called Zener polarons involving ferromagnetic coupling between pairs of transition metal ions have been observed . These quasi-particles are commonly formed in a variety of materials, including polar semiconductors, ionic crystals, organic semiconductors, and hybrid perovskites . The introduction of polarons has been demonstrated to exert a significant influence on a range of properties, including light absorption, charge separation and transfer, surface reactivity, molecular adsorption/desorption, and local electronic characteristics . Nevertheless, their relationship to the reaction path in the OER has only recently been the subject of investigation, resulting in reducing the overpotential of the reaction-determining step and affecting the band alignment at the solid/liquid interface that competes with the evolution of the water-splitting reaction .
