This book describes recent breakthroughs that promise major cost reductions in solar energy production in a clear and highly accessible manner. The author addresses the three key areas that have commonly resulted in criticism of solar energy in the past: cost, availability, and variability. Coverage includes cutting-edge information on recently developed 40 efficient solar cells, which can produce double the power of currently available commercial cells. The discussion also highlights the potentially transformative emergence of opportunities for integration of solar energy storage and natural gas combined heat and power systems. Solar energy production in the evening hours is also given fresh consideration via the convergence of low cost access to space and the growing number of large terrestrial solar electric power fields around the world. Dr. Fraas has been active in the development of Solar Cells and Solar Electric Power Systems for space and terrestrial applications since 1975. His research team at Boeing demonstrated the first GaAs/GaSb tandem concentrator solar cell in 1989 with a world record energy conversion efficiency of 35, garnering awards from Boeing and NASA. He has over 30 years of experience at Hughes Research Labs, Chevron Research Co, and the Boeing High Technology Center working with advanced semiconductor devices. In a pioneering paper, he proposed the InGaP/GaInAs/Ge triple junction solar cell predicting a cell terrestrial conversion efficiency of 40 at 300 suns concentration. Having become today’s predominant cell for space satellites, that cell is now entering high volume production for terrestrial Concentrated Photovoltaic (CPV) systems. Since joining JX Crystals, Dr. Fraas has pioneered the development of various thermophotovoltaic (TPV) systems based on the new GaSb infrared sensitive PV cell. Dr. Fraas holds degrees from Caltech (B.Sc. Physics), Harvard (M. A. Applied Physics), and USC (Ph.D. EE).

Solar energy is a substantial global industry, one that has generated trade disputes among superpowers, threatened the solvency of large energy companies, and prompted serious reconsideration of electric utility regulation rooted in the 1930s. One of the biggest payoffs from solar’s success is not the clean inexpensive electricity it can produce, but the lessons it provides for innovation in other technologies needed to address climate change. Despite the large literature on solar, including analyses of increasingly detailed datasets, the question as to how solar became inexpensive and why it took so long still remains unanswered. Drawing on developments in the US, Japan, Germany, Australia, and China, this book provides a truly comprehensive and international explanation for how solar has become inexpensive. Understanding the reasons for solar’s success enables us to take full advantage of solar’s potential. It can also teach us how to support other low-carbon technologies with analogous properties, including small modular nuclear reactors and direct air capture. However, the urgency of addressing climate change means that a key challenge in applying the solar model is in finding ways to speed up innovation. Offering suggestions and policy recommendations for accelerated innovation is another key contribution of this book. This book will be of great interest to students and scholars of energy technology and innovation, climate change and energy analysis and policy, as well as practitioners and policymakers working in the existing and emerging energy industries.

This book thoroughly examines the technical parameters of photovoltaic systems, and appraises their net energy balance from production, operation and maintenance, to recycling. Similar performance and yield analysis is applied to optical, thermal, and electrical parameters and interfaces. Professor Krauter demonstrates how accurate yield calculations, optimal system performance, and new prototypes aid in cost reduction. Examples, tables and figures are included.

Here is the truth that the powerful Dirty Energy public relations machine doesn't want you to know: the ascent of solar energy is upon us. Solar-generated electricity has risen exponentially in the last few years and employment in the solar industry has doubled since 2009. Meanwhile, electricity from coal has declined to pre-World War II levels as the fossil fuel industry continues to shed jobs. Danny Kennedy systematically refutes the lies spread by solar's opponents—that it is expensive, inefficient, and unreliable; that it is kept alive only by subsidies; that it can't be scaled; and many other untruths. He shows that we need a rooftop revolution to break the entrenched power of the coal, oil, nuclear, and gas industries Solar energy can create more jobs, return our nation to prosperity, and ensure the sustainability and safety of our planet. Now is the time to move away from the dangerous energy sources of the past and unleash the amazing potential of the sun.
