Integrazione di celle fotovoltaiche ibride nel vetromattone

2012

L’invenzione riguarda l’integrazione del vetromattone con celle solari ibride (organiche/inorganiche), conosciute come Dye-sensitized Solar Cell (DSC). La combinazione del vetromattone con le DSC consente di migliorare le prestazioni del prodotto originario rendendolo in grado di produrre energia pulita. Le caratteristiche di trasparenza e isolamento termo-acustico del prodotto possono essere regolate agendo sulla configurazione delle DSC. Il prodotto può essere assemblato a formare pannelli fotovoltaici per la realizzazione di facciate traslucide energeticamente “attive” in varie condizioni luminose (condizioni di luce diffusa o artificiale) e indipendentemente dall’angolo di radiazione so…

The integration of Dye-sensitized Solar Cell (DSC) with the glassblock is disclosed. The combination of the two technological elements the glassblock and the DSC module enhance their own peculiarities. The final complete product is ready-made for installation owns the qualities of the glassblock and produces sustainable energy at the same time. The transparency and the thermo-acoustic insulation may be modulated according to the specific requirements of each case of installation. The product may be used for example to create PV panels for glazed and translucent façades that are able to perform efficiently in all light conditions (even in diffuse light also converting internal artificial light) that are not dependant on the angle of the solar radiation and do not suffer from the high operative temperatures of functioning due to the peculiarities of the DSCs. DSCs are made of economic and biocompatible materials and are produced with low-cost and highly productive printing methods on rigid or flexible substrates. With the integration of DSC modules with the glassblock PV panels coincide with the envelope itself so that they do not need any further structures to be installed on and allow the possibility of subtract from the price of the panel the price of the substituted building element allowing further economies. DSCs can be printed in different colours and with various patterns offering to designers and customers the possibility of intervening on the glassblock aesthetical aspect also taking advantage of the peculiar modularity of the glassblock for larger compositions of drawings on the building’s façade. Seven Hypotheses of integration are discussed in order to obtain DSC-integrated glassblock ready for the construction of a precast and dry-assembled PV panel which can use the horizontal and vertical cavities between the glassblocks to house plastic profiles where the electric interconnections and the steel bars -useful for improve the mechanical resistance of the panel- are integrated.Settore ICAR/10 - Architettura Tecnica

Innovative Photovoltaic Translucent Components for the Building Envelope

2014

International directives that regulates buildings energy efficiency and environmental sustainability establish strict parameters for the construction of a new generation of “Zero Energy Buildings” indicating transmittance limits for building envelope components and encouraging the use of renewable sources. In this sense, the PV sector aims at the definition of novel efficient solutions for the integration in the building envelope, standing out for their multifunctional features. After an overview on the main PV technologies and building integrated applications, focusing on semi-transparent envelope solutions, the paper shows the results of a research that is being carried out at the Departm…

Pannello precompresso di vetromattoni assemblati a secco per la realizzazione di involucri traslucidi

2012

L’invenzione riguarda la realizzazione di un pannello di vetromattoni montati “a secco” -da impiegare per la realizzazione di involucri edilizi traslucidi anche nel caso di edifici alti- che è in grado di rispondere adeguatamente alle sollecitazioni orizzontali (quali quelle dovute a vento e sisma) grazie all’applicazione della tecnica della precompressione mondirezionale. Per offrire una risposta ai limiti imposti dalla tecnica di assemblaggio tradizionale dei vetromattoni (“ad umido”), l’applicazione della precompressione consente, infatti, di dare ai pannelli preassemblati “a secco” una rigidezza adeguata anche in direzione normale al loro piano di posa, sfruttando le buone caratteristic…

The invention is related to the construction of a glassblock panel “dry assembled” that can be used to build translucent building envelope even in high-rise buildings. This panel is able to contrast the horizontal actions due to wind and earthquake by means of the application of unidirectional pre-stressing technique. To overcame the limits due to the “wet assembly” system traditionally used to assemble the glassblocks the use of prestressing technique allow the panels to have an adequate mechanical resistance against the actions perpendicular to their installation plane. In this configuration the mechanical resistance of the glassblocks is exploited. The unidirectional prestressing (along the prevalent dimension of the panel) is obtained through the grip of the nuts inserted in the steel bars that are housed inside the glassblocks supporting profiles positioned in the vertical cavities between the glassblocks and passing through the horizontal profiles useful to separate glassblock rows from each other. The proper nuts grip opposing to the steel plates positioned at the top and bottom of the panel allow to prestress the panel. The steel plate are positioned on a plastic plate fixed to the lateral faces of the glassblocks by means of resins.Settore ICAR/10 - Architettura Tecnica

“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…

In this article the fi rst results of the performance analysis of the photovoltaic glassblock are given. The photovoltaic glassblock is an innovative product which integrates third generation solar cells (DSSC) invented for the construction of translucent building envelopes energetically effi cient and “active” able to reduce the energy consumption in buildings and to produce at the same time green energy. The analysis was conducted on four different hypotheses of integration through numerical simulations in order to evaluate the energy absorption and the optical performance of the device. The software simulations represent a fi rst step for the understanding of the performance of the element and prelude to an experimental analysis session. The results of a research conducted about national and international patents publications on the DSSC technology and its applications will be illustrated too. The data collected during this research had been organized in a digital database.Settore ICAR/10 - Architettura Tecnica
