Abstract
We report the growth and characterization of low-bandgap record-efficiency ZnO/CdS/CuInSe2 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/m2, 25°C, AM1·5 Global). The improved performance of the CuInSe2 solar cell is primarily due to a high current density. Material and device characterization data are presented.
