In the case of high photovoltaic (PV) penetration into the electricity grid, the energy produced by a PV system that is effectively used (useful energy) depends on the energy yield and on how this energy is managed to avoid detrimental effects occurring at ...
Scattering particles constitute a key light trapping solution for thin film photovoltaics where either the particles are embedded in the light absorbing layer or a thick layer of them is used as a reflector. Here we introduce a monolayer of wavelength-scal ...
Silicon is today the main material used in electronics. It is a very advanced and mature technology. It is therefore clear that new technological concepts and materials should be introduced through the integration on the silicon platform. III-V semiconduct ...
We report and explain the photoluminescence (PL) spectra from crystalline silicon (c-Si) wafers passivated by hydrogenated amorphous silicon (a-Si:H) films under various measurement conditions, utilizing the different absorption coefficients and radiative ...
This study presents the performance of GF-mats loaded with TiO2 and Cu under solar/visible light leading to bacterial inactivation and pollutant degradation at both solid-air and solid-liquid interfaces. The GF-mats show effective water disinfection, self- ...
Cryo electron tomography allows macromolecular complexes within vitrified, intact, thin cells or sections thereof to be visualized, and structural analysis to be performed in situ by averaging over multiple copies of the same molecules. Image processing fo ...
The goal of this thesis is to master the synthesis of GaAs nanowires ensembles on Si for their application in solar cells. Semiconductor nanowires present promising characteristics for photovoltaic applications: they benefit from their longitudinal high as ...
Organic semiconductors have recently emerged as a promising alternative to standard inorganic semiconductors for many commercial applications. Their ability to be processed from solution combined with their unique mechanical resistance paves the way for lo ...
Polycrystalline chemical vapour deposited ZnO films are commonly used as transparent electrodes for photovoltaic devices. Over the past years much effort has been put into improving their properties. Even though these films are now well optimised for speci ...
A salient characteristic of solar cells is their ability to subject photo-generated electrons and holes to pathways of asymmetrical conductivity-'assisting' them towards their respective contacts. All commercially available crystalline silicon (c-Si) solar ...
