The Building Research Laboratories (ELDI) of the Polytechnic University of Cartagena has since this summer with a new space seething innovative ideas.
PhD in Renewable Energy UPCT are investigating under the direction of Professor Salvador Gomez Lopera dispersed for the manufacture of photovoltaic cells and piezoelectric materials nanoparticles.
To test these nanoparticles, the industrial engineer José María López has designed and implemented an automated machine manufacturing electrodes and counter electrodes for solar cells sensitized by dye or quantum dot, with that expected "yield between 40 and 50% of that energy received, compared to 20% who get the best silicon cells, "explains the researcher.
Nanoparticles dispersed works also on another doctoral student, Juan Manuel Mariñoso, seeking to generate photovoltaic energy from the reaction in the light of praseodymium-doped titanium dioxide, one of the compositions which are working now.
"The aim is to improve the performance of photovoltaic conversion and cost / performance ratio," said the young student of Master program and PhD in Renewable Energy UPCT, among other methods, you are using X-ray diffraction for characterization at the atomic level of the crystallographic structure of these new materials through complex computational techniques calculation. "
In the laboratory of Nanoparticles and Dispersions it has also begun investigating a student with a previous very different training.
The architect Alejandro Albero is synthesizing nanoparticles of zinc and zinc oxide for use in the manufacture of electrodes, electrical energy storage (batteries) and piezoelectric collectors electricity production.
These materials serve to manufacture devices with applications in buildings, such as flexible sheets attached to doors and windows that produce electricity by pressure on the surface of the device taking advantage of the piezoelectric effect, manifested by exerting on the material mechanical force which orients molecules same polarizing surface.
These devices operate driven by building users during their daily activities.
