Solar Cell Device Physics offers a balanced, in-depth qualitative and quantitative treatment of the physical principles and operating characteristics of solar cell devices. Topics covered include photovoltaic energy conversion and solar cell materials and structures, along with homojunction solar cells. Semiconductor-semiconductor heterojunction cells and surface-barrier solar cells are also discussed. This book consists of six chapters and begins by introducing the reader to the basic physical principles and materials properties that are the foundations of photovoltaic energy conversion, with emphasis on various photovoltaic devices capable of efficiently converting solar energy into usable electrical energy. The electronic and optical properties of crystalline, polycrystalline, and amorphous materials with both organic and inorganic materials are considered, together with the manner in which these properties change from one material class to another and the implications of such changes for photovoltaics. Generation, recombination, and bulk transport are also discussed. The two mechanisms of photocarrier collection in solar cells, drift and diffusion, are then compared. The remaining chapters focus on specific solar cell device classes defined in terms of the interface structure employed: homojunctions, semiconductor-semiconductor heterojunctions, and surface-barrier devices. This monograph is appropriate for use as a textbook for graduate students in engineering and the sciences and for seniors in electrical engineering and applied physics, as well as a reference book for those actively involved in solar cell research and development.

""The Timeless Tapestry of Stone: Beauty, Function, and Conservation"" offers a comprehensive exploration of stones, weaving together their aesthetic value, practical applications, and the urgent need for conservation. This interdisciplinary work traces humanity's relationship with stones from prehistoric tools to modern engineering marvels, highlighting their significance in art, industry, and environmental sustainability. The book presents stones not as inert objects, but as dynamic elements connecting us to Earth's history and human creativity. Structured to guide readers through a logical progression, the book begins with fundamental stone properties before delving into their roles in art, architecture, and mechanical engineering. It culminates in a discussion of conservation efforts and sustainable stone utilization. What sets this work apart is its holistic approach, bridging fields such as geology, anthropology, and environmental science to offer a unique perspective on how stones intersect with human culture and technology. The author draws upon a wide range of evidence, including geological data and cutting-edge materials science research, to support its arguments. Balancing academic rigor with accessibility, ""The Timeless Tapestry of Stone"" appeals to both specialists and general readers interested in natural history, engineering, or environmental issues. It offers practical knowledge for artisans and designers while providing theoretical insights for students and professionals in geology and environmental studies. By interweaving scientific knowledge, cultural insights, and practical wisdom, the book invites readers to see stones as bridges connecting our past, present, and future.

This document serves as the third revision of the USAF Parachute Handbook which was first published in 1951. The data and information represent the current state of the art relative to recovery system design and development. The initial chapters describe representative recovery applications, components, subsystems, material, manufacture and testing. The final chapters provide empirical data and analytical methods useful for predicting performance and presenting a definitive design of selected components into a reliable recovery system.
