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

Highlights

• The electrical parameters of perovskite solar cells revealed by immittance spectroscopy

• Intrinsic properties of materials and their correlation with device performance

• Charge carrier dynamics and response of a working solar cell under illumination

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.
