Cartografia tematica geologica, geomorfologica e vegetazionale nella valutazione di impatto ambientale. Analisi del progetto della circonvallazione d…
2004
L’utilizzo della cartografia tematica all’interno di un Sistema Informativo Territoriale (SIT) ha condotto, attraverso una serie di procedure originali, alla valutazione dell’impatto (VIA) prodotto su alcune componenti ambientali dall’eventuale realizzazione di un nuovo tracciato stradale a scorrimento veloce tra il comune di Mezzolombardo (TN) e l’imbocco della Val di Non nei pressi della località la Rocchetta. Per gli scopi di questa analisi, sono state realizzate, attraverso il rilevamento di terreno, carte di dettaglio a scala 1:5.000 di tipo geologico, geomorfologico e vegetazionale direttamente inserite all’interno di un SIT. La cartografia geologica tiene conto, oltre che della compo…
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 …
Instabilities Effects in Thin Film Solar Cells: Reversible Ageing, Performance Recovery and Improvement by Electrical Stresses
An Open Innovation Decision Support System to Select a Biopharmaceutical R&D Portfolio
2016
Drugs available in the market today, selected several years ago under very uncertain future scenario, have experienced a long and expensive process of research and development carried out following both a closed and an open innovation path. To support this critical selection process, we propose a Decision Support System, able to choose among different candidates the most promising drugs along their best development path. The Decision Support System, based on a real options portfolio optimization model, mapping tools, and what-if rules as well, has been applied to a numerical example available in literature, and the research findings show interesting managerial and academic implications
An Intelligent System for Decision Support in Bioinformatics
2011
The enormous array of computational techniques and data available due to today's use of high-throughput technologies can be quite overwhelming for researchers investigating biological problems. For any problem, there are many possible models and algorithms giving different results. We present a new Intelligent System that supports the selection, configuration and operation of strategies and tools in the bioinformatics domain. The Institute for High Performance Computing and Networking (ICAR-CNR) and the University of Palermo are developing an intelligent system that supports bioinformatics research. The system guides the researcher in building a data analysis workflow and acts as an interfa…
Electro-optical characterization of ruthenium-based dye sensitized solar cells: A study of light soaking, ageing and temperature effects
2017
Abstract In this work, we report on the electro-optical characterization of Dye Sensitized Solar Cells (DSSCs) which use ruthenium complexes as sensitizers. In particular, several kinds of measurements have been performed to study the electrical performances and the efficiency levels of the cells at different operating conditions. In detail, the measurements have been conducted at varying temperatures and hours of light soaking. Our results show that the short circuit current density J SC , the open circuit voltage V OC and the conversion efficiency η increase with the hours of light soaking, while they decrease with temperature. A thorough investigation on the light soaking process at the …
One diode circuital model of light soaking phenomena in Dye-Sensitized Solar Cells
2018
Abstract In this work, we report on the modelling of light soaking effect on Ruthenium-based Dye Sensitized Solar cells (DSSCs). Such a phenomenon can be detected when exposing the cells at increasing hours of illumination and produces a reversible performance increase. Starting from the results obtained through the electro-optical characterization of the cells, we applied a one-diode circuital-model. Our results show a good agreement between the experimental and the simulated data, with a mean square error in the order of 10−12 and a maximum error in current lower than 0.6%. Finally such results allowed us to infer some precise trends followed by the cells main electrical parameters and of…

Comparison on the use of PV systems in the vertical walls
2015
In this article the preliminary evaluation of the performance of a photovoltaic window is presented. The aim is to trace the behavior of next-generation systems, which favor architectonical integration. Three different systems have been taken into account: a dye sensitized solar cell (DSSC), blue and grey caved silicon panels. The systems can be placed behind a window or behind a wall of glass blocks.
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 …
