Emission of Rhodamine B in PMMA opals for luminescent solar concentrators
2012
In conventional luminescent solar concentrators (LSC) incident light is absorbed by luminophores and emitted isotropically. Most of the emitted light is trapped inside the LSC by total internal reflection and guided to solar cells at the edges. Light emitted towards the surfaces, however, is lost in the escape cone. Furthermore, when the luminophore emits light in its absorption range, light is lost due to reabsorption. To overcome these losses, we embed the luminescent material in photonic structures to influence the emission characteristics. Directional and spectral redistribution of emission is supposed to enhance the light guiding in LSCs and reduce reabsorption losses. For this purpose…
Luminescent Solar Concentrator (LSC): preliminary phases of the LCA analysis applied to the Smart Window-LSC
2019
Luminescent solar concentrators (LSC) represent one of the innovative technologies related to Building Integrated PhotoVoltaics (BIPV). T hanks to their characteristic of being semi-transparent and of functioning both with direct and diffused radiation, the se devices can be integrated to the surface of the buildings, in particular in replacement of openings such as skylights or windows. They do not require solar tracking systems that are used in classic solar concentrators and allow reducing the presence of silicon compared to traditional photovoltaic panels.
Energy evaluation and life cycle assessment of an innovative building integrated technology: the smart window-luminescent solar concentrator
2022
Luminescent Solar Concentrators (LSC) represent one of the innovative and potentially most versatile technologies related to Building Integrated Photovoltaics (BIPV). The peculiarity of these devices lies in the fact that they can be integrated into the surface of the building to replace openings such as skylights or windows, thanks to their characteristic of being semi-transparent and of functioning both with direct and diffused radiation. Eni developed the own technology Eni Ray Plus® based on LSC and integrated it in a multifunctional smart window-LSC (SW-LSC) prototype. The device uses the energy produced by LSC modules to power an autonomous and passive shading system, exploiting irrad…
Luminescent Solar Concentrator (LSC): principio di funzionamento e fasi preliminari dell’analisi LCA applicata alla Smart Window-LSC
2019
Una delle tecnologie più promettenti nel panorama dei sistemi fotovoltaici integrati negli edifici è quella dei concentratori solari luminescenti (LSC - Luminescent Solar Concentrator). La peculiarità di questi dispositivi risiede nel fatto che possono essere installati in zone dell’edificio difficilmente sfruttabili da altre tecnologie fotovoltaiche, in particolare in sostituzione di aperture quali lucernari o finestre, grazie alla loro caratteristica di essere semi-trasparenti e di funzionare sia con radiazione solare diretta che diffusa. L’obiettivo del presente lavoro è stato ricostruire i percorsi di produzione dei principali componenti del pannello LSC, in modo da ottenere un parziale…
A validated energy model of a solar dish-Stirling system considering the cleanliness of mirrors
2020
Solar systems based on the coupling of parabolic concentrating collectors and thermal engines (i.e. dish-Stirling systems) are among the most efficient generators of solar power currently available. This study focuses on the modelling of functioning data from a 32 kWe dish-Stirling solar plant installed at a facility test site on the University of Palermo campus, in Southern Italy. The proposed model, based on real monitored data, the energy balance of the collector and the partial load efficiency of the Stirling engine, can be used easily to simulate the annual energy production of such systems, making use of the solar radiation database, with the aim of encouraging a greater commercialisa…
