With regard to photovoltaic cells, there is, the 1st, 2nd and 3rd generations. One can also cite the 3rd generation of organic cells, which are sensitized colorant. This new energy conversion device used in a manufacturing titanium dioxide (TiO2) low cost compared with silicon that is used in conventional solar cells. The dye-sensitized cells based on the use of a colorant capable of transferring an electron in the excited state for a semiconductor, in this case, titanium dioxide, starting the process that leads to the current generation. Thus, the aim of this study was to reproduce a methodology described in most articles on the related theme, but as it got a result, there was a need to reorganize methods. The best methodology adopted was diluted titanium oxide directly to the colorant, not to cause loss of the material when immersed, thereby obtaining the operation of the cell is monitored by voltage measurement. A particularity is still being studied, about the fact that we cover the cell and it still continue to store voltage, not decreasing instantly, thus generating a doubt that it can behave like a battery and generate voltage and current. It was not possible to assess the yield percentage of the cell because the cell mounting in series for this check is required. In later studies, we intend to analyze the voltage with the change of time and the power to ascend one led lamp, thus obtaining results for graphics generation, parameters, such as the contact area that is receiving the sunlight, materials best they could conduct current for more cost effective, and the analysis of other types of colorants.
