"Impedance spectroscopy is a powerful technique for the characterization of third generation photovoltaic cells. This non-destructive method provides valuable information about the internal dynamical mechanisms, such as charge diffusion, charge recombination, and charge accumulation, which are essential for the performance and stability of these photovoltaic devices. By applying an alternating voltage signal and analyzing the resulting current response, impedance spectroscopy can reveal the complex interplay between different species and interfaces within the cell. This talk aims to provide an overview of the principles and applications of impedance spectroscopy in the study of organic and perovskite solar cells, highlighting its potential to contribute to the ongoing optimization and commercialization of these promising technologies."
