This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Construction of the basic apparatus has been completed during this period, and many apparatus checks have been completed. Almost complete SiH4 dissociation has been obtained in approx. 950 C ovens between the turbo and rough pumps, so that reliable, long-term operation is achieved. A base vacuum of approx. 10−7 Torr is achieved in the discharge chamber in a few hours, and approx. 10−8 overnight, so that gas-phase impurity levels as low as 10−7 are ready achievable. The SiH4 inlet lines are entirely bakeable stainless steel and permanently closed to air, to maintain the tank purity of SiH4. A distillation procedure to further clean the tank SiH4 is under study. Thus we should be able to study the effects of very small, controlled levels of impurities. The discharge configurations are shown, and the ratios of SixH/sub n/ fluxes for three types of discharges in pure SiH4 are given. (WHK).

Download or read book Solar Cells and Modules written by Arvind Shah and published by Springer Nature. This book was released on 2020-07-16 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a comprehensive introduction to the field of photovoltaic (PV) solar cells and modules. In thirteen chapters, it addresses a wide range of topics including the spectrum of light received by PV devices, the basic functioning of a solar cell, and the physical factors limiting the efficiency of solar cells. It places particular emphasis on crystalline silicon solar cells and modules, which constitute today more than 90 % of all modules sold worldwide. Describing in great detail both the manufacturing process and resulting module performance, the book also touches on the newest developments in this sector, such as Tunnel Oxide Passivated Contact (TOPCON) and heterojunction modules, while dedicating a major chapter to general questions of module design and fabrication. Overall, it presents the essential theoretical and practical concepts of PV solar cells and modules in an easy-to-understand manner and discusses current challenges facing the global research and development community.

Download or read book The Foundations of Vacuum Coating Technology written by Donald M. Mattox and published by William Andrew. This book was released on 2018-08-21 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Foundations of Vacuum Coating Technology, Second Edition, is a revised and expanded version of the first edition, which was published in 2003. The book reviews the histories of the various vacuum coating technologies and expands on the history of the enabling technologies of vacuum technology, plasma technology, power supplies, and low-pressure plasma-enhanced chemical vapor deposition. The melding of these technologies has resulted in new processes and products that have greatly expanded the application of vacuum coatings for use in our everyday lives. The book is unique in that it makes extensive reference to the patent literature (mostly US) and how it relates to the history of vacuum coating. The book includes a Historical Timeline of Vacuum Coating Technology and a Historical Timeline of Vacuum/Plasma Technology, as well as a Glossary of Terms used in the vacuum coating and surface engineering industries. History and detailed descriptions of Vacuum Deposition Technologies Review of Enabling Technologies and their importance to current applications Extensively referenced text Patents are referenced as part of the history Historical Timelines for Vacuum Coating Technology and Vacuum/Plasma Technology Glossary of Terms for vacuum coating

Download or read book The 2030 Spike written by Colin Mason and published by Earthscan. This book was released on 2003 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: The clock is relentlessly ticking Our world teeters on a knife-edge between a peaceful and prosperous future for all, and a dark winter of death and destruction that threatens to smother the light of civilization. Within 30 years, in the 2030 decade, six powerful 'drivers' will converge with unprecedented force in a statistical spike that could tear humanity apart and plunge the world into a new Dark Age. Depleted fuel supplies, massive population growth, poverty, global climate change, famine, growing water shortages and international lawlessness are on a crash course with potentially catastrophic consequences. In the face of both doomsaying and denial over the state of our world, Colin Mason cuts through the rhetoric and reams of conflicting data to muster the evidence to illustrate a broad picture of the world as it is, and our possible futures. Ultimately his message is clear; we must act decisively, collectively and immediately to alter the trajectory of humanity away from catastrophe. Offering over 100 priorities for immediate action, The 2030 Spike serves as a guidebook for humanity through the treacherous minefields and wastelands ahead to a bright, peaceful and prosperous future in which all humans have the opportunity to thrive and build a better civilization. This book is powerful and essential reading for all people concerned with the future of humanity and planet earth.
