Physica Status Solidi - Rapid Research Letters, doi:10.1002/pssr.2021005101862-6254https://doi.org/10.1002/pssr.202100510https://hdl.handle.net/11492/5764WOS:000731408300001The small perturbation frequency-resolved techniques have been powerful tools in unraveling the kinetic processes governing the operation of perovskite solar cells (PSCs). One such technique is electrochemical impedance spectroscopy (EIS). However, a thorough interpretation of the EIS response of PSCs is still lacking owing to the absence of a uniform electrical equivalent circuit. In this context, intensity-modulated photocurrent/photovoltage spectroscopy (IMPS/IMVS) can be the link between the optical and electrical responses of PSCs and complement the IS technique. In this review, the progress made in interpreting the IMPS/IMVS response of various types of PSCs is summarized and diverse prospects are discussed. First, the basic theory and models present in the literature are discussed. Next, the IMPS/IMVS response of mesoporous and planar PSCs based on various physical parameters is discussed. At last, proposed future prospects for the development of this field are discussed.enCharge TransportIntensity-Modulated Photocurrent SpectroscopyIntensity-Modulated Voltage SpectroscopyPerovskite Solar CellsRecombinationsOtherinfo:eu-repo/semantics/closedAccess2-s2.0-85121424746WOS:00073140830000110.1002/pssr.202100510Q2Q2
