Abstract

In this work, we present a comprehensive individual modeling approach to investigate the optical properties of a Perovskite solar cell by the ellipsometry analysis of a Methylammonium Lead Iodide (MAPbI3) perovskite/PEDOT:PSS/ITO film stack on a glass substrate. The absorption coefficient obtained from the model was compared to the ultraviolet-visible (UV-Vis) spectroscopy measured absorption spectra, while the optical constants are compared with values reported in literature. We propose that spectroscopic ellipsometry characterization can be used at the different stages of the PSCs fabrication process in order to understand the different mechanisms that impact the final performance of a photovoltaic device.
