Properties of 19.2% efficiency ZnO/CdS/CuInGaSe2 thin-film solar cells


  • This article is a U.S. Government work and is in the public domain in the U.S.A.


We report the growth and characterization of record-efficiency ZnO/CdS/CuInGaSe2 thin-film solar cells. Conversion efficiencies exceeding 19% have been achieved for the first time, and this result indicates that the 20% goal is within reach. Details of the experimental procedures are provided, and material and device characterization data are presented. Published in 2003 by John Wiley & Sons, Ltd.
