This book was released on 2006 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a new thin-film solar cell structure in which the traditional transparent conductive oxide electrode (ZnO) is replaced by a transparent conductive coating consisting of a network of bundled single-wall carbon nanotubes. Optical transmission properties of these coatings are presented in relation to their electrical properties (sheet resistance), along with preliminary solar cell results from devices made using CuIn1-xGaxSe2 thin film absorber materials. Achieving an energy conversion efficiency of>12% and a quantum efficiency of ~80% demonstrate the feasibility of the concept.
