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

Surfaces of minimal degree of tame representation type and mutations of Cohen–Macaulay modules

2017

We provide two examples of smooth projective surfaces of tame CM type, by showing that any parameter space of isomorphism classes of indecomposable ACM bundles with fixed rank and determinant on a rational quartic scroll in projective 5-space is either a single point or a projective line. For surfaces of minimal degree and wild CM type, we classify rigid Ulrich bundles as Fibonacci extensions. For the rational normal scrolls S(2,3) and S(3,3), a complete classification of rigid ACM bundles is given in terms of the action of the braid group in three strands.

A Dynamic Electrical Scheme for the optimal reconfiguration of PV modules under non-homogeneous solar irradiation

2012

This paper presents a strategy for the maximization of the output power of photovoltaic (PV) systems under non homogeneous solar irradiation by means of automatic reconfiguration of the PV arrays layout. The innovation of the proposed approach is the employment of a simple Dynamic Electrical Scheme (DES), allowing a large number of possible modules interconnection, to be installed between the PV generator and the inverter. The models of the PV generator and of the DES have been realized and simulated with Simulink (Dynamic System Simulation for MATLAB). The attained experimental results appear to be quite interesting in terms of the attainable benefit in power and thus energy terms. The lim…

Impact of the Solar Irradiation Angle on the Work of Modules with Spherical Cells - Simulation

2018

The main purpose of all PV modules is to convert solar energy into electricity, but in the era of building integrated photovoltaics, there are additional opportunities to use them. The use of them as a composite of architectural structures in the form of facade cladding, roofing, stained glass windows or noise barriers on highways, in addition to generating electricity embellish also the aesthetic value of the facilities. However, these atypical their use, cause that the modules should have quite different properties then in the traditional application, which is related to their unusual way of positioning. Particularly for structures such as the modules made of spherical cells with the two …

Thin Film CIGS Solar Cells, Photovoltaic Modules, and the Problems of Modeling

2013

Starting from the results regarding a nonvacuum technique to fabricate CIGS thin films for solar cells by means of single-step electrodeposition, we focus on the methodological problems of modeling at cell structure and photovoltaic module levels. As a matter of fact, electrodeposition is known as a practical alternative to costly vacuum-based technologies for semiconductor processing in the photovoltaic device sector, but it can lead to quite different structural and electrical properties. For this reason, a greater effort is required to ensure that the perspectives of the electrical engineer and the material scientist are given an opportunity for a closer comparison and a common language.…

W artykule przedstawiono postęp w zakresie uzyskiwanych sprawności przez ogniwa i moduły fotowoltaiczne (PV) wykonane z różnych materiałów i za pomocą różnych technologii. Zawarto w nim szczegółowe zestawienia tabelaryczne sprawności oraz ich parametrów technicznych. Zwrócono uwagę na nowe obiecujące technologie, które jeszcze nie mają rekordowych sprawności, ale z uwagi na proces ich wytwarzania rokują nadzieje na uzyskanie bardzo dużych sprawności albo tanich wielkopowierzchniowych modułów do komercyjnego zastosowania. Ponadto, omówiono ekonomiczne skutki wdrożenia nowo zawartych zapisów w uchwalonej w lutym 2015 r. Ustawie o Odnawialnych Źródłach Energii (OZE) dla rozwoju rozproszonych i…
