Book Description
En raison de leur mise en forme facile et de leur faible coût, les polymères font l'objet de nombreuses études en vue d'applications industrielles. C'est le cas des dispositifs photovoltaïques plastiques. Le rendement de conversion et la stabilité de ces systèmes sont les points les plus importants à améliorer. La première partie de notre travail porte sur la réalisation et la caractérisation d'une cellule photovoltaïque à base du composite MEH-PPV et PCBM. L'insertion des couches interfaciales, le traitement de surface et l'amélioration de la morphologie de la couche active nous ont permis d'accroître significativement les performances photovoltaïques de la structure par rapport aux performances antérieures (>2,5%). Les deuxième et troisième parties portent, respectivement, sur l'évaluation de nouveaux matériaux organiques dans les cellules à base de composite et sur le développement d'une nouvelle structure de cellules photovoltaïques améliorant la stabilité.

Book Description
Photovoltaics, the direct conversion of light from the sun into electricity, is an increasingly important means of distributed power generation. The SPICE modelling tool is typically used in the development of electrical and electronic circuits. When applied to the modelling of PV systems it provides a means of understanding and evaluating the performance of solar cells and systems. The majority of books currently on the market are based around discussion of the solar cell as semiconductor devices rather than as a system to be modelled and applied to real-world problems. Castaner and Silvestre provide a comprehensive treatment of PV system technology analysis. Using SPICE, the tool of choice for circuits and electronics designers, this book highlights the increasing importance of modelling techniques in the quantitative analysis of PV systems. This unique treatment presents both students and professional engineers, with the means to understand, evaluate and develop their own PV modules and systems. * Provides a unique, self-contained, guide to the modelling and design of PV systems * Presents a practical, application oriented approach to PV technology, something that is missing from the current literature * Uses the widely known SPICE circuit-modelling tool to analyse and simulate the performance of PV modules for the first time * Written by respected and well-known academics in the field

Book Description
The book is a history of Molecular Beam Epitaxy (MBE) as applied to the growth of semiconductor thin films (note that it does not cover the subject of metal thin films). It begins by examining the origins of MBE, first of all looking at the nature of molecular beams and considering their application to fundamental physics, to the development of nuclear magnetic resonance and to the invention of the microwave MASER. It shows how molecular beams of silane (SiH4) were used to study the nucleation of silicon films on a silicon substrate and how such studies were extended to compound semiconductors such as GaAs. From such surface studies in ultra-high vacuum the technique developed into a method of growing high quality single crystal films of a wide range of semiconductors. Comparing this with earlier evaporation methods of deposition and with other epitaxial deposition methods such as liquid phase and vapour phase epitaxy (LPE and VPE). The text describes the development of MBE machines from the early 'home-made' variety to that of commercial equipment and show how MBE was gradually refined to produce high quality films with atomic dimensions. This was much aided by the use of various in-situ surface analysis techniques, such as reflection high energy electron diffraction (RHEED) and mass spectrometry, a feature unique to MBE. It looks at various modified versions of the basic MBE process, then proceed to describe their application to the growth of so-called 'low-dimensional structures' (LDS) based on ultra-thin heterostructure films with thickness of order a few molecular monolayers. Further chapters cover the growth of a wide range of different compounds and describe their application to fundamental physics and to the fabrication of electronic and opto-electronic devices. The authors study the historical development of all these aspects and emphasise both the (often unexpected) manner of their discovery and development and the unique features which MBE brings to the growth of extremely complex structures with monolayer accuracy.

Book Description
Advanced materials are the basis of modern science and technology. This proceedings volume presents a broad spectrum of studies of novel materials covering their processing techniques, physics, mechanics, and applications. The book is concentrated on nanostructures, ferroelectric crystals, materials and composites, materials for solar cells and also polymeric composites. Nanotechnology approaches, modern piezoelectric techniques and also latest achievements in materials science, condensed matter physics, mechanics of deformable solids and numerical methods are presented. Great attention is devoted to novel devices with high accuracy, longevity and extended possibilities to work in wide temperature and pressure ranges, aggressive media etc. The characteristics of materials and composites with improved properties opening new possibilities of various physical processes, in particular transmission and receipt of signals under water, are described.
