About this ebook
Since the first publication of this important volume over a decade ago, dramatic changes have taken place with the solar market growing almost 100-fold and the U.S. moving from first to fourth place in the world market as analyzed in this Second Edition. Three bold new opportunities are identified for any countries wanting to improve market position. The first is combining pin solar cells with 3X concentration to achieve economic competitiveness near term. The second is charging battery-powered cars with solar cell generated electricity from arrays in surrounding areas including the car owners' homes while simultaneously reducing their home electricity bills by over ninety percent. The third is formation of economic "unions" of sufficient combined economic size to be major competitors.
In this updated edition, feed-in tariffs are identified as the most effective approach for public policy. Reasons are provided to explain why pin solar cells outperform more traditional pn solar cells. Field test data are reported for nineteen percent pin solar cells and for ~500X concentrating systems with bare cell efficiencies approaching forty percent. Paths to bare cell efficiencies over fifty percent are described, and key missing program elements are identified. Since government support is needed for new technology prototype integration and qualification testing before manufacturing scale up, the key economic measure is identified in this volume as the electricity cost in cents per kilowatt-hour at the complete installed system level, rather than just the up-front solar cell modules' costs in dollars per watt.
This Second Edition will benefit technologists in the fields of solar cells and systems; solar cell researchers; power systems designers; academics studying microelectronics, semiconductors, and solar cells; business students and investors with a technical focus; and government and political officials developing public policy.

About the author
Lewis M. Fraas, PhD, is the founder and President of JX Crystals Inc. He has spearheaded the development of high-power-density photovoltaic cells and complete concentrating photovoltaic and thermophotovoltaic systems. Dr. Fraas wrote the first paper describing the forty percent-efficient triple-junction concentrator solar cell now entering high-volume production, and his group at Boeing demonstrated the first thirty-five percent-efficient dual-junction cell.
Larry D. Partain, PhD, is Director of Marketing and Advanced Technology, initiating and managing high-risk/high-payoff R&D programs for Varian Medical Systems. A prominent researcher in solar cell and related X-ray imager technology, Dr. Partain recently led efforts to develop high-performance X-ray and flat-panel imaging medical systems, helping to create over $100 million in company sales.
