This easily accessible textbook provides an overview of solar to electric energy conversion, followed by a detailed look at one aspect, namely photovoltaics, including the underlying principles and fabrication methods. Professor Wolf, an experienced author and teacher, reviews such green technologies as solar-heated-steam power, hydrogen, and “artificial leaf” approaches, as well as nuclear fusion. The energy generation in the sun is explained and applied to terrestrial fusion reactors.

The book is self-contained so as to be suitable for students with introductory calculus-based courses in physics, chemistry, or engineering. It introduces concepts in quantum mechanics, atomic and molecular physics, plus the solid state and semiconductor junction physics needed to attain a quantitative understanding of the current status of this field. With its comments on economic aspects, it is also a useful tool for those readers interested in a career in alternative energy.
