Properties of ZnO/CdS/CuInSe₂solar cells with improved performance

Abstract

Abstract We report the growth and characterization of low‐bandgap record‐efficiency ZnO/CdS/CuInSe 2 thin‐film solar cells. The total area conversion efficiency for this cell is 14·5%. This result has been measured and confirmed at the National Renewable Energy Laboratory under standard reporting conditions (1000 W/m 2 , 25°C, AM1·5 Global). The improved performance of the CuInSe 2 solar cell is primarily due to a high current density. Material and device characterization data are presented.. Published in 2004 by John Wiley & Sons, Ltd.
