Along last years, perovskite solar cells have shown an impressive progress both in the performance and in stability, what has made this technology a candidate with high probabilities of accessing soon to practical applications.1-3 However, the description ofof their fundamental electrical properties still present some aspects that are not completely understood. In this work impedance spectroscopy analysis will be used to study charge transport, transfer and accumulation properties of the different components of perovskite solar cells and at the interfaces between them. Special attention will be focused in the description of the contribution of each of these elements in the current-voltage curve which is used to determine the performance of the solar cells. Effects such humidity absorption or negative capacitance will be also described. 4, 5
