The solar cells sensitized with dyes (DSSC) are third generation photovoltaic cells
in which the material that absorbs the radiation is a dye, organic or inorganic,
which is absorbed in another material by which the generated electrons are
propagated. In this work, organic dyes, trees such as blackwood and mangrove,
were characterized to know the properties and their feasibility for use in DSSC
cells. The dyes were obtained mangrove and blackwood powder, obtained the
grinding and thermogravimetric treatment of the bark obtained the trees.
Subsequently, they were extracted using solvents, water and ethanol. The
characterization was carried out using infrared spectroscopy (IR) and visible
ultraviolet spectroscopy (UV-Vis). The results obtained both techniques indicate
the presence of the functional groups necessary for use in sensitized solar cells,
and the stability of these functional groups was confirmed after the anchoring
of the dyes in the semiconductor oxide.
