This proceedings volume compiles 123 papers that were presented orally or as posters at the National Center for Photovoltaics (NCPV) Program Review Meeting, held in Denver, Colorado, on September 8-11, 1998. The purpose of this meeting was to highlight the advances made in various areas of photovoltaics by and through the NCPV during the period of December 1997 to September 1998. Topics covered ranged from research in crystalline silicon and thin-film technologies, to manufacturing of photovoltaic modules, to applications of and markets for photovoltaic products.
Research and development of photovoltaic solar cells is playing an ever larger practical role in energy supply and ecological conservation all over the world. Many materials science problems are encountered in understanding existing solar cells and the development of more efficient, less costly, and more stable cells. This important and timely book provides a historical overview, but concentrates primarily on exciting developments in the last decade. It describes the properties of the materials that play an important role in photovoltaic applications, the solar cell structures in which they are used, and the experimental and theoretical developments that have led to the most promising contenders./a
This is the second volume of a 3-volume history of solar power generating systems covering the approximately 50 years of research and development surrounding the energy crisis of 1973. Volume 1 covered solar-thermal systems. The present volume covers photovoltaic systems in the 20th century. Volume 3 will cover photovoltaic developments from the start of the 21st century. The history is based upon keynote lectures given by international specialists at the Sede Boqer Symposia on Solar Electric Power Production, a series that commenced in 1986. The lectures document many technical details that have become hard to find, including some pertaining to technologies that were successfully demonstrated but subsequently discontinued owing to their not having been deemed to be cost-effective at the time. However, in the event that different economic considerations may ensue, these volumes can provide a valuable starting point, including references, for the re-investigation of some of those once abandoned ideas.
Sustainable development encompasses economic, social, and ecological perspectives of conservation and change in natural resources. It is generally defined as development that meets the needs of the present without compromising the ability of future generations to meet their own needs. This definition is based on the ethical imperative of equity within and between generations. Moreover, apart from meeting; "the basic needs of all"; sustainable development implies sustaining the natural life support systems on Earth, and extending to all the opportunity to satisfy their aspirations for a better life. Hence, sustainable development is more precisely defined as a process of change in which the exploitation of resources, the direction of investments, the orientation of technological development, and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspiration. To date, various definitions and stationary-state criteria of sustainability have been proposed. Many authors have been concerned with only part of the problem, such as the technological assumptions, the ability to substitute natural resources in economic transformation processes, and the resilience and importance of ecological processes. But, the social dimension did not receive the same attention, and has not been adequately integrated into formal analysis. The engineering community has to play an important role in sustainable development with appropriate evaluation of the engineering systems. In this respect energy, water and environment systems require multi-criteria evaluation methods for the assessment of the economic, environmental and social aspect of the systems.
