Along of the last years, a great interest in renewable and sustainable energy
production has emerge with a constant increase, as a result of the interest to
decrease fossil fuel consumption, pollution and contamination caused by the
human activity. Main advantage of this kind of energy production includes low
generation of polluting agents, reduction in cost of energy and decentralization
and diversification of production systems. Among them, solar energy has the
highest growth ratio due to some factors like an easy inclusion in the
conventional energy networks and high conversion efficiency, reason why many
investigations have been focused in increase the efficiency of solar cells
decreasing the production cost and using environmental friendly materials.
According to it, Dye Sensitized Solar Cells (DSSC) have been developed and a
great opportunity to increase the energy production has been open with them.
By this way, we propose the development of DSSC based in organic colorants
and Cu doped titanium dioxide, using a photoelectrode composed by a double
layer changing the porosity and doping percentage in each one of them, trying
to increase voltage and current intensity as a result of high conductivity and
available sites for dye deposition. Some tests carried out on the photoelectrode
includes sem spectroscopy, characterization by UV-VIS and FTIR spectroscopy,
and test of energy production was carried out on the cell to determine some
factors like voltage, current intensity, fill factor and conversion efficiency.
