This work seeks to contribute to development of new photovoltaic materials to be used in low cost solar cells and low environmental impact. Special emphasis was placed on the study of electric transport properties in perovskite solar cells with structure FTO/ZnO/MAPI/P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> HT/Au, using impedance spectroscopy technique.

Through simulations of impedance curves, it was possible to model the electrical behavior of the cells, where simulated circuit elements values were found: R0,RS1, RS2, cg and CS. From the above, the resistance at low frequencies RS1 has higher values than the component RS2 at high frequencies (HF) and since these have an inverse relationship with the recombination current Jrec,s we can say that photocurrent losses by recombination are greater at HF.
