Protocol for Deciphering the Electrical Parameters of Perovskite Solar Cells Using Immittance Spectroscopy

Summary Here, we present a protocol for the fabrication of inverted (p-i-n)-type perovskite solar cells, unraveling its electrical merits via immittance spectroscopy. The immittance spectroscopy is a prevailing technique for both qualitative and quantitative analyses of charge carrier dynamics in working devices. This technique integrates the temperature-dependent capacitance–frequency (C-f) spectra, impedance spectra, and Mott-Schottky analyses. This protocol is also applicable for typical (n-i-p) perovskite solar cells and other multilayer semiconductor devices. For complete details on the use and execution of this protocol, please refer to Khan et al. (2019, 2021).
