Flexible Organic Photovoltaic Solar Cells (FOPSC) have drawn intense attention due to their advantages over competing solar cell technologies. The method utilized to deposit as well as to integrate solutions and processed materials, manufacturing organic solar cells by the Electrodeposition System, has been presented in this research. The FOPSC Device constructed in this work is electrochromic device with solar cell are the base Poly (3,4-ethylenedioxythiophene), PEDOT:PSS, Poly(3-hexyl thiophene, P3HT, Phenyl-C61-butyric acid methyl ester, PCBM and Polyaniline, PANI, were deposited in Indium Tin Oxide, ITO, and characterized by Electrical Measurements and Scanning Electron Microscopy (SEM). In addition, the thin film obtained by the deposition of PANI, prepared in perchloric acid solution, was identified through PANI-X1. The maximum process temperature was 120°C, which corresponds to the baking of the active polymeric layer. The result obtained by electrical Measurements has demonstrated that the PET/ITO/PEDOT:PSS/P3HT:PCBM Blend/ PANI-X1/ITO/PET layer presents the characteristic curve of standard solar cell after spin-coating and electrodeposition. The Thin film obtained by electrodeposition of PANI-X1 on P3HT/PCBM Blend was prepared in perchloric acid solution. Furthermore, these flexible organic photovoltaic solar cells presented power conversion efficiency of 12% and the inclusion of the PANI-X1 layer reduced the effects of degradation on these organic photovoltaic panels induced by solar irradiation. The thermal effects from ultraviolet irradiation under the device’s surface, in the irradiation simulator chamber, demonstrated a 15% reduction in the device’s lifetime. The inclusion of the PANI-X1 layer reduced the effects of degradation these organic photovoltaic panels induced for solar irradiation, a fact that also observed in the irradiation in the simulation chamber. In Scanning Electron Microscopy (SEM) these studies reveal that the surface of PANI-X1 layers is strongly conditioned by the surface morphology of the dielectric.
