Abstract

One of the most promising alternatives from the point of view technology is to fabrication of solar cells sensitized with dyes natural as they have been shown to have a relatively high efficiency at a low cost of production. In particular, the motivation of the present research work is based in addition to the above mentioned, in the constant search for new materials and processes for the manufacture of solar cells. We are particularly interested in developing methods ecological and that are friendly with the environment. The present work reports the results obtained from the study of the manufacture and characterization of solar cells type DSSC (Dye Sensitized Solar Cells) with TiO<subscript>2</subscript> sensitized with organic dyes obtained from cactus fruit and hibiscus flower. The electrodes were constructed with TiO<subscript>2</subscript>, through the deposit of Dr. Blade, while the conductive glass counter electrodes were coated with graphite of a common pencil and commercial iodine was used as electrolyte. The cactus fruit red ink extraction was carried out by extraction alcoholic using sodium carbonate, while hibiscus ink is obtained by maceration. Optical characterization of both dyes was carried out by UV-Vis spectroscopy. Adhesive tapes were used in the construction of the TiO<subscript>2</subscript> electrodes to obtain different thicknesses and find an optimal thickness to have good efficiencies. The results of the characterizations showed that the sensitized cells with better efficiency. [ABSTRACT FROM AUTHOR]
