Photovoltaic technology stands out as one of the most promising renewable energy sources. Specifically, hybrid and organic solar cells have reached remarkable efficiency levels at the laboratory scale. However, challenges related to their stability remain a critical area of investigation for advancing their commercialization, driving a rapid surge in research over recent years. In this symposium, we want to shed light on the most important questions about the degradation mechanisms in photovoltaics, providing a collaborative platform for the growing, multidisciplinary community of scientists dedicated to device characterization.

Juan A. Anta is Full Professor of Physical Chemistry at the University Pablo de Olavide, Seville, Spain. He obtained a BA in Chemistry in the Universidad Complutense of Madrid (Spain) and carried out his PhD research at the Physical Chemistry Institut of the National Research Council of Spain. His research focuses on fundamental studies of energy photoconversion processes, especially on dye and perovskite solar cells, using numerical simulation and modelling tools, as well as advanced optoelectronic characterization techniques such as impedance spectroscopy and other small perturbation techniques.
Juan Bisquert (pHD Universitat de València, 1991) is a Distinguished Research Professor at Instituto de Tecnología Química (Universitat Politècnica de València-Consejo Superior de Investigaciones Científicas). He is Executive Editor for Europe of the Journal of Physical Chemistry Letters. He has been distinguished in the list of Highly Cited Researchers from 2014 to 2024. The research activity of Juan Bisquert has been focused on the application of measurement techniques and physical modeling in several areas of energy devices materials, using organic and hybrid semiconductors as halide perovskite solar cells. Currently the main research topic aims to create miniature devices that operate as neurons and synapses for bio-inspired neuromorphic computation related to data sensing and image processing. The work on this topic combines harnessing hysteresis and memory properties of ionic-electronic conducting devices as memristors and transistors towards computational networks. The work is supported by European Research Council Advanced Grant.
Luis OnoSandheep Ravishankar is currently a team leader in the photovoltaics department (IMD-3) at Forschungszentrum Jülich, Germany. He is interested in all aspects of the characterization and simulation of the device physics in perovskite single-junction and tandem solar cells. He uses a combination of electrical methods, luminescence methods and drift-diffusion simulations for this purpose, followed by the development of analytical or semi-analytical models for parameter estimation.
