Optoelectronics of Solar Cells
Book by Greg Smestad


Click to order Optoelectronics of Solar CellsOptoelectronics of Solar Cells, by Greg Smestad, is now available and can be ordered below.

With concerns over worldwide environmental security, global warming, and climate change due to emissions of CO from the burning of fossil fuels, it is desirable to have a wide range of energy technologies in a nation's portfolio. These technologies can be used in domestic markets, or exported to other nations, helping them to leapfrog to a cleaner, and less carbon intensive, energy path.

Solar cells have already proven themselves a viable option as a nonpolluting renewable energy source in many applications. It is advantageous to optical engineers to have at least a basic knowledge of how these devices function, and of the important parameters that control their operation. Optoelectronics of Solar Cells is designed to be an overview for those in the fields of optics and optical engineering, as well as those who are interested in energy policy, economics, and the requirements for efficient photo-to-electric energy conversion.

The book was developed from conference courses taught by the author for SPIE, and was inspired by his numerous publications.
