Solar Cells and Their Applications
A major update of solar cell technology and the solarmarketplace
Since the first publication of this important volume over adecade ago, dramatic changes have taken place with the solar marketgrowing almost 100-fold and the U.S. moving from first to fourthplace in the world market as analyzed in this Second Edition. Threebold new opportunities are identified for any countries wanting toimprove market position. The first is combining pin solar cellswith 3X concentration to achieve economic competitiveness nearterm. The second is charging battery-powered cars with solarcell–generated electricity from arrays in surroundingareas—including the car owners' homes—whilesimultaneously reducing their home electricity bills by over ninetypercent. The third is formation of economic "unions" of sufficientcombined economic size to be major competitors.
In this updated edition, feed-in tariffs are identified as themost effective approach for public policy. Reasons are provided toexplain why pin solar cells outperform more traditional pn solarcells. Field test data are reported for nineteen percent pin solarcells and for ~500X concentrating systems with bare cellefficiencies approaching forty percent. Paths to bare cellefficiencies over fifty percent are described, and key missingprogram elements are identified. Since government support is neededfor new technology prototype integration and qualification testingbefore manufacturing scale up, the key economic measure isidentified in this volume as the electricity cost in cents perkilowatt-hour at the complete installed system level, rather thanjust the up-front solar cell modules' costs in dollars perwatt.
This Second Edition will benefit technologists in the fields ofsolar cells and systems; solar cell researchers; power systemsdesigners; academics studying microelectronics, semiconductors, andsolar cells; business students and investors with a technicalfocus; and government and political officials developing publicpolicy.
