Protocol for deciphering the electrical parameters of perovskite solar cells using immittance spectroscopy.

Here, we present a protocol for the fabrication of inverted ()-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 () spectra, impedance spectra, and Mott-Schottky analyses. This protocol is also applicable for typical () 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).
