Description

Several forms of thin-film solar cells are being examined as alternatives to silicon-solar cells—one of the most promising technologies is the dye-sensitized solar cell (DSC), with proven efficiencies that approach 11%. This book, which provides a comprehensive look at this promising technology, aims to provide both a graduate level text that brings together the fundamentals of DSC from three perspectives (materials, performance, and mechanistic aspects), as well as to serve as an advanced monograph that summarizes the key advances and lists the technical challenges remaining to be solved.
