Dye-sensitized solar cells (DSSC's) are devices that can convert sunlight to energy and have in composition a semiconductor oxide and a suitable photosensitizer. Due to the high cost, the research for new materials applied in solar cells arouses great interest. This work aims to study hybrid solar cells of FTO/TiO2/dye interface, produced with different low cost natural photosensitizers, extracted in acidified ethanoic solution of different natural products: plum, grape, urucum and eggplant. The techniques of characterization used were: UV-VIS Spectroscopy, Fourier Transform Infrared Spectroscopy (FT-IR), Open Circuit Potential as function of time (Voc), Photocronoamperometry curves (PCA) and Photocurrent Density Curves as function of Potential (j-V). The dyes tested in the DSSC presented the character of photosensitivity, with the adsorption in TiO2 films and the maximum absorption on the visible region. The DSSC with the best photovoltaic parameters was using the dye extracted from the plum, generating a solar cell with ƞ = 0.12±0.03%, Voc = 572±12 mV, FF = 0.57±0.01 and jsc = 0.40±0.09 mA cm-2 .
