Moduli DSSC integrati nel vetromattone per la costruzione di pannelli traslucidi fotovoltaici multifunzionali
2012
La proposta illustrerà i primi risultati ottenuti nell’ambito di una ricerca, tutt’ora in corso presso il Dipartimento di Architettura dell’Università degli Studi di Palermo, finalizzata ad indagare le problematiche connesse all’integrazione del vetromattone con sistemi di produzione di energia rinnovabile, in particolare, di terza generazione (DSC-Dye Syntetized solar cell - celle fotovoltaiche organiche/ibride). I principali campi di investigazione che si illustreranno saranno connessi alle: tecniche ed i processi di deposizione delle celle sul vetromattone per la costruzione dei moduli, alla scelta del loro migliore posizionamento ed all’analisi delle ricadute, in termini di valutazione …

DSSC-integrated Glassblocks for the construction of Sustainable Building Envelopes
2014
The paper shows the first results of the optical performance analysis carried out on the DSSC integrated glassblock, an innovative building product developed at the Department of Architecture of the University of Palermo. In the field of a research that is being conducted in order to define innovative solutions for the construction of photovoltaic and energy efficient translucent building envelopes, different hypotheses of integration of DSSC into the glassblock have been foreseen. The integration of glassblock with third generation PV systems allows to define a novel building-PV product that meets the current requirements of the BIPV (Building Integrated Photovoltaics) market. By means of …
Performance of the Glass Block in Photovoltaic Generation
2015
In this article is presented the preliminary evaluation of the performance of radiation transmission of glass block, used in support of photovoltaic cells, investigating different internal surface points of the block, which are subject to different shading during daylight hours. The aim is to establish how the edging setting, the only opaque element, can reduce the amount of light radiation during the day, introducing in this way a reduction of efficiency of the entire generation system. The generation system can be based on traditional photovoltaic cells or on the most suitable dye sensitized solar cells. An experimental measurement setup employing a microprocessor-based instrument has bee…
Integrazione di celle solari di terza generazione nel vetromattone per la realizzazione di pannelli traslucidi fotovoltaici. Analisi prestazione e st…
2013
L’articolo illustra i primi risultati ottenuti nell’ambito dell’analisi prestazionale del vetromattone fotovoltaico, un prodotto edilizio innovativo derivato dall’integrazione di celle fotovoltaiche di terza generazione (DSSC) nel vetromattone, ideato per la realizzazione di involucri traslucidi energeticamente effi cienti ed “attivi”, in grado di ridurre i consumi energetici degli edifi ci e di produrre, al contempo, energia verde. L’analisi è stata condotta su quattro differenti ipotesi di integrazione. Attraverso simulazioni numeriche si è effettuata una valutazione dell’energia assorbita dagli strati attivi oltre che delle prestazioni ottiche complessive del dispositivo. Lo studio anali…
Vetromattone fotovoltaico. Moduli con celle "dye sensitized" integrati nel vetromattone per la costruzione di pannelli traslucidi fotovoltaici multif…
2013
Nel panorama architettonico contemporaneo l’utilizzo di superfici vetrate per la realizzazione di involucri edilizi trasparenti o traslucidi risulta particolarmente diffuso sia nel caso di edifici costruiti ex novo che di edifici esistenti interessati da operazioni di retrofit, anche laddove gli stessi risultano localizzati in aree geografiche caratterizzate da condizioni climatiche “avverse” a causa degli elevati livelli di irraggiamento. Le normative internazionali in materia di risparmio energetico e di sostenibilità ambientale stabiliscono, poi, parametri precisi da rispettare per la realizzazione di una nuova generazione di edifici ad energia “Zero”, imponendo limiti ai valori di trasm…
Integration of Dye-Sensitized Solar Cells with Glassblock
2012
The paper will show the first results of a research (included in a larger work about the Improvement of glassblocks performance in order to use them for the construction of sustainable translucent building envelops even in Mediterranean and Tropical Areas) aimed to the integration of glassblock with the DSC technology. Glassblock is a high-performance type of glass in the field of sustainable architectural claddings: the process of deposition of the cells on the single glassblock, their best position and the performance of this new kind of glassblock, DSC integrated, will be discussed in the paper in terms of transmittance, light transmission and aesthetical effects, together with the probl…
“Building Integrated Photovoltaics and DSSC-Glassblocks"
2012
According to many market analysts, Building Integrated Photovoltaics (BIPV) represents the future of photovoltaic (PV) industry as well as one of the strategies for the achievement of zero-energy building standards and UE goals for the next years. Dye-sensitised solar cell (DSSC) is a low-cost and very versatile solar technology, offering a wide range of possibilities in terms of colour, transparency and design: hence DSSC are particularly suited for BIPV and could give a big contribution in this direction. Starting from those considerations, this paper will show the first results of a research aimed at the integration of DSSC with the glassblock for the construction of multifunctional tran…
Optical Performance Evaluation of DSSC-integrated Glassblocks for Active Building Façades
2015
The paper outlines the results of a research, carried out at the University of Palermo, aimed at the assessment of the energy performance of a novel glassblock integrated with 3rd generation Dye-Sensitized Solar Cells (DSSC), which, when installed into panels, allows obtaining translucent building envelopes able to provide high thermal and visual comfort levels while producing clean energy. The paper focuses on the optical analyses of four different configurations of DSSC-integrated glassblocks, carried out by using the optical design software Zemax. The values of optical transmittance, the solar factor and the electric power – calculated for each configuration – are discussed.
