The significant advancements in perovskite solar cell (PSC) research and development have reignited optimism for the practicality of solar energy. A deeper comprehension of the fundamental mechanisms is essential for enhancing the current solar technology. Impedance spectroscopy (IS) characterization, in conjunction with other analytical methods, stands out as the primary approach for gaining insights into the internal workings of solar cells. The continuous analysis and refinement of electrochemical spectroscopy data for PSCs have unveiled intricate operational details. Despite the ongoing improvements, the absence of a centralized repository for this information poses challenges for tracking progress effectively. This review paper aims to consolidate the physical phenomena behind the development of PSC research, aiming to establish a comprehensive knowledge base on impedance plots, equivalent circuits, and related processes.
