Available in PDF, EPUB and Kindle. Book excerpt: The world of today must face up to two contradictory energy problems: on the one hand, there is the sharply growing consumer demand in countries such as China and India. On the other hand, natural resources are dwindling. Moreover, many of those countries which still possess substantial gas and oil supplies are politically unstable. As a result, renewable natural energy sources have received great attention. Among these, solar-cell technology is one of the most promising candidates. However, there still remains the problem of the manufacturing costs of such cells. Many attempts have been made to reduce the production costs of conventional solar cells (manufactured from monocrystalline silicon using diffusion methods) by instead using cheaper grades of silicon, and simpler pn-junction fabrication. That is the hero of this book; the heterojunction solar cell.

Download or read book FTIR Studies of H related Defects in Dilute III N V Alloys and Crystalline Si Photovoltaics written by Suppawan Kleekajai and published by . This book was released on 2007 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, hydrogen-containing defects in two semiconducting material systems are studied: dilute III-N-V alloys (GaAsN and GaPN), and crystalline silicon. In both material systems, H has a significant effect on electronic properties. In dilute III-N-V alloys, there has been tremendous interest due to a large bandgap reduction caused by the introduction of N. Hydrogenation of these materials increases the band gap energy to near the value of the N-free host. A defect called [special characters omitted](N) was proposed by many theorists to be the cause of band gap recovery in GaAsN and GaPN. We used vibrationa spectroscopy to investigated GaAsN and GaPN alloys into which H and/or D had been introduced. Our results show that the N-H complex in the III-N-V alloys contains two weakly-coupled N-H(D) stretching modes. This conclusion is inconsistent with the [special characters omitted](N) defect. Later, a new model consisting of a canted NH2 complex in GaAsN was proposed. We performed an IR absorption study with uniaxial stress to investigate the symmetry of the NH2 complex. Our results showed that the NH2 complex has C2v symmetry or lower. This conclusion is consistent with the canted NH2 complex. H is introduced into Si solar cells to increase their efficiency. Two common ways of introducing H are by the post-deposition annealing of a SiN x-coating that acts as an anti-reflection coating and by H-plasma exposure. We have studied the hydrogenation mechanisms of crystalline Si by using infrared spectroscopy. For these experiments, floating-zone Si that contained Pt impurities that act as traps for H was used as a model system in which H could be directly detected. In this model system, the concentration and indiffusion depth of H were determined for different hydrogenation methods so that their effectiveness could be compared. The post-deposition annealing of a hydrogen-rich SiN x surface layer was found to introduce H into the Si bulk with a concentration of ∼1015 cm3 under the best conditions investigated here.
Download or read book Spectroscopy of Rubbers and Rubbery Materials written by Victor M. Litvinov and published by iSmithers Rapra Publishing. This book was released on 2002 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the application of spectroscopic techniques for characterisation of chemical and physical structures in viscoelastic materials, such as unvulcanised elastomers and their vulcanisates, various rubbery materials and some plastics, which when blended with particular additives (plasticisers) behave like rubbers. Analysis of the rubbery materials is complicated by the fact that rubbery products, such as tyres, tubes, seals, V-belts and hoses, contain in the rubbery matrix a significant amount of various compounds, i.e., fillers, vulcanising agents, antioxidants and plasticisers. Due to the complex composition, no single technique can provide a good understanding of the effect of chemical and physical structures on the functional properties of rubbery materials. Thus spectroscopy has become a powerful tool for the determination of polymer structures. The most comprehensive information on chemical and physical structures in relation to material properties can be obtained by using a combination of macroscopic techniques and methods that provide information on the molecular level. frequently used for analysis of rubbery materials, i.e., various methods of nuclear magnetic resonance (NMR) and optical spectroscopy. The main objective of this present book is to discuss a wide range of applications of the spectroscopic techniques for the analysis of rubbery materials. The book brings together the various spectroscopic techniques for obtaining the following information: chemical structure of rubbery materials, network structure analysis, heterogeneity of rubbery materials, physical properties of rubbery materials, functional properties and stability of rubbery materials, processing of rubbery materials and quality control. The contents of this book are of interest to chemists, physicists, material scientists and technologists who seek a better understanding of rubbery materials.

Download or read book Photovoltaic and Photoactive Materials written by Joseph M. Marshall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this NATO Advanced Study Institute (ASI) was to present an up-to-date overview of various current areas of interest in the field of photovoltaic and related photoactive materials. This is a wide-ranging subject area, of significant commercial and environmental interest, and involves major contributions from the disciplines of physics, chemistry, materials, electrical and instrumentation engineering, commercial realisation etc. Therefore, we sought to adopt an inter disciplinary approach, bringing together recognised experts in the various fields while retaining a level of treatment accessible to those active in specific individual areas of research and development. The lecture programme commenced with overviews of the present relevance and historical development of the subject area, plus an introduction to various underlying physical principles of importance to the materials and devices to be addressed in later lectures. Building upon this, the ASI then progressed to more detailed aspects of the subject area. We were also fortunately able to obtain a contribution from Thierry Langlois d'Estaintot of the European Commission Directorate, describing present and future EC support for activities in this field. In addition, poster sessions were held throughout the meeting, to allow participants to present and discuss their current activities. These were supported by what proved to be very effective feedback sessions (special thanks to Martin Stutzmann), prior to which groups of participants enthusiastically met (often in the bar) to identify and agree topics of common interest.
