This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les cellules photovoltaïques (PV) des modules ou panneaux solaires, sont protégées des agressions extérieures par des résines polymères encapsulantes qui, pour la plupart, sont des matériaux élastomériques réticulés. L'optimisation et le contrôle de l'étape d'encapsulation peut permettre un gain de productivité et augmenter la durée de vie des modules, ce qui réduit les coûts de l'électricité générée. Deux voies ont ainsi été explorées dans ce travail : 1) La première concerne l'étude de l'état de réticulation de l'encapsulant majoritairement utilisé actuellement, un copolymère d'éthylène et d'acétate de vinyle connu sous le nom d'EVA ; celui-ci est mis en œuvre sous forme de feuilles ou films. Une faible réticulation de l'encapsulant peut mener, entre autre, à son fluage lors de son utilisation, impactant directement la durée de vie du module. Il est donc important de suivre le niveau de réticulation de l'encapsulant lors des opérations de contrôle. La comparaison de différentes méthodes d'évaluation du degré de réticulation ont donc été menées ; 2) La deuxième voie concerne des études autour d'un nouveau procédé d'encapsulation. En effet, le procédé industriel actuel, inclut une étape dite de « lamination », pendant laquelle l'encapsulant est fondu et réticulé autour des cellules. Cette étape relativement longue crée des contraintes thermomécaniques pouvant limiter la durée de vie des modules PV. Le développement d'un nouveau procédé d'encapsulation où l'encapsulant en film est remplacé par un encapsulant liquide photopolymérisable permettrait de diminuer les coûts de production tout en augmentant potentiellement la durée de vie des modules. Les propriétés rhéologiques et la cinétique de polymérisation de ce nouvel encapsulant sont ainsi étudiées. Enfin les deux voies d'encapsulation sont comparées. Il a été montré que d'un point de vue des performances électriques le nouveau procédé présente un avantage potentiel et que d'un point de vue de la tenue au vieillissement il est équivalent au procédé industriel actuel.

Book Synopsis Chemistry of Aluminium, Gallium, Indium and Thallium by : A.J. Downs
Download or read book Chemistry of Aluminium, Gallium, Indium and Thallium written by A.J. Downs and published by Springer Science & Business Media. This book was released on 1993-05-31 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Boron has all the best tunes. That may well be the first impression of the Group 13 elements. The chemical literature fosters the impression not only in the primary journals, but also in asteady outflowofbooks focussing more or less closely on boron and its compounds. The same preoccupation with boron is apparent in the coverage received by the Group 13 elements in the comprehensive and regularly updated volume of the Gmelin Handbook. Yet such an imbalance cannot be explained by any inherent lack ofvariety, interest or consequence in the 'heavier elements. Aluminium is the most abundant metal in the earth's crust; in the industrialised world the metal is second only to iron in its usage, and its compounds can justifiably be said to touch our lives daily - to the potential detriment of those and other lives, some would argue. From being chemical curios, gallium and indium have now gained considerably prominence as sources of compound semiconductors like gallium arsenide and indium antimonide. Nor is there any want ofincident in the chemistriesofthe heavier Group 13 elements. In their redox, coordination and structural properties, there is to be found music indeed, notable not always for its harmony but invariably for its richness and variety. Thisbook seeks to redress the balance with a definitive, wide-rangingand up-to-date review of the chemistry of the Group 13 metals aluminium, gallium, indium and thallium.

Book Synopsis Surface Photovoltage Analysis Of Photoactive Materials by : Thomas Dittrich
Download or read book Surface Photovoltage Analysis Of Photoactive Materials written by Thomas Dittrich and published by World Scientific. This book was released on 2020-02-04 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface photovoltage (SPV) techniques provide information about photoactive materials with respect to charge separation in space. This book aims to share experience in measuring and analyzing SPV signals and addresses researchers and developers interested in learning more about and in applying SPV methods. For this purpose, basics about processes in photoactive materials and principles of SPV measurements are combined with examples from research and development over the last two decades.SPV measurements with Kelvin probes, fixed capacitors, electron beams and photoelectrons are explained. Details are given for continuous, modulated and transient SPV spectroscopy. Simulation principles of SPV signals by random walks are introduced and applied for small systems. Application examples are selected for the characterization of silicon surfaces, gallium arsenide layers, electronic states in colloidal quantum dots, transport phenomena in metal oxides and local charge separation across photocatalytic active crystallites.

Book Synopsis Organic Solid-State Lasers by : Sébastien Forget
Download or read book Organic Solid-State Lasers written by Sébastien Forget and published by Springer. This book was released on 2013-07-03 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic lasers are broadly tunable coherent sources, potentially compact, convenient and manufactured at low-costs. Appeared in the mid 60’s as solid-state alternatives for liquid dye lasers, they recently gained a new dimension after the demonstration of organic semiconductor lasers in the 90's. More recently, new perspectives appeared at the nanoscale, with organic polariton and surface plasmon lasers. After a brief reminder to laser physics, a first chapter exposes what makes organic solid-state organic lasers specific. The laser architectures used in organic lasers are then reviewed, with a state-of-the-art review of the performances of devices with regard to output power, threshold, lifetime, beam quality etc. A survey of the recent trends in the field is given, highlighting the latest developments with a special focus on the challenges remaining for achieving direct electrical pumping of organic semiconductor lasers. A last chapter covers the applications of organic solid-state lasers.

Book Synopsis Building Wireless Community Networks by : Rob Flickenger
Download or read book Building Wireless Community Networks written by Rob Flickenger and published by "O'Reilly Media, Inc.". This book was released on 2003 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building Wireless Community Networks is about getting people online using wireless network technology. The 802.11b standard (also known as WiFi) makes it possible to network towns, schools, neighborhoods, small business, and almost any kind of organization. All that's required is a willingness to cooperate and share resources. The first edition of this book helped thousands of people engage in community networking activities. At the time, it was impossible to predict how quickly and thoroughly WiFi would penetrate the marketplace. Today, with WiFi-enabled computers almost as common as Ethernet, it makes even more sense to take the next step and network your community using nothing but freely available radio spectrum. This book has showed many people how to make their network available, even from the park bench, how to extend high-speed Internet access into the many areas not served by DSL and cable providers, and how to build working communities and a shared though intangible network. All that's required to create an access point for high-speed Internet connection is a gateway or base station. Once that is set up, any computer with a wireless card can log onto the network and share its resources. Rob Flickenger built such a network in northern California, and continues to participate in network-building efforts. His nuts-and-bolts guide covers: Selecting the appropriate equipment Finding antenna sites, and building and installing antennas Protecting your network from inappropriate access New network monitoring tools and techniques (new) Regulations affecting wireless deployment (new) IP network administration, including DNS and IP Tunneling (new) His expertise, as well as his sense of humor and enthusiasm for the topic, makes Building Wireless Community Networks a very useful and readable book for anyone interested in wireless connectivity.
