Perovskite Paradigm: Unraveling Photoelectrochemical Synergies for Sustainable Transformations

Abstract

Owing to the tunable electronic properties, high carrier lifetimes, low recombination possibility, and long diffusion lengths, perovskites have gained attention for potential use in photoelectrocatalytic processes. Photoelectrochemical methods can convert sunlight into electricity or useful fuels, resulting in extensive research to develop PEC applications. This chapter embarks on a comprehensive exploration of the perovskite structure’s transformative influence on diverse photoelectrochemical cell (PEC) and monolithic Photovoltaic-Electrocatalytic (PV-EC) devices including water splitting, H2 evolution, CO2 reduction, N2 reduction, degradation of pollutants, (bio) sensing, and organic synthesis. By assessing the mechanisms and kinetics involved, we aim to disclose the potential of perovskite-based photoelectrochemical systems in shaping the landscape of green energy and environmental stewardship. Furthermore, the chapter addresses the progress and challenges in enhancing the stability, selectivity, and efficiency of perovskite-based PEC and monolithic PV-EC reactions to unravel the synergistic potential for sustainable transformations in the realm of photoelectrochemistry.
