-
The photovoltaic conversion of sun light energy into electricity constitutes a viable, clean and renewable alternative for electric energy production. A wide variety of different materials have been proposed over the last ...
-
(Date of defense: 10-07-2015)The objective of this work was to study two different light management approaches to enhance the efficiency of thin film Si solar cells and these were the manipulation of the light path (light trapping) and changing the ...
-
The tendency towards cost reduction in the photovoltaic industry has led to the development of the so-called thin film silicon technology. Among the different possible morphologies, a material that presents very promising ...
-
(Date of defense: 24-10-2014)Nanoscience and Nanotechnology have experienced a tremendous growth in few years. Nanotechnologies are the design, characterization, production and application of structures, devices and systems by controlling shape and ...
-
(Date of defense: 07-01-2013)The first block of this thesis deals with the study of the degradation process of tungsten catalytic filaments in the field of silicon deposition with the Hot Wire Chemical Vapour Deposition (HWCVD) technique. The development ...
-
(Date of defense: 14-11-2014)In 2004 there were newly conditions for a scientific revolution, with very important technology implications and yet to be completely developed. It is the isolation of atomic carbon layers, better known as graphene, whose ...
-
(Date of defense: 03-07-2012)After an intense development of optical tweezers as a biophysical tool during the last decades, quantitative experiments in living cells have not found in this technique its best ally, due, in part, to the lack of a reliable ...
-
Esta tesis presenta un estudio de la síntesis y la caracterización de carbono amorfo tipo diamante (DLC) preparado en capa delgada. Este material destaca por exhibir una alta dureza, baja fricción y buena resistencia al ...
-
Theoretical methods to compute accurate x-ray spectra emitted from targets bombarded with kV electrons are required for quantification in Electron Probe Microanalysis (EPMA), especially for the analysis of non-homogeneous ...
-
(Date of defense: 10-05-2012)Multiferroic materials are those materials in which more than one ferroic order coexist. The most technologically appealing multiferroic materials are those showing ferromagnetism and ferroelectricity. Coupling between the ...
