Abstract :
The characteristics of polycrystalline, thin film CuIn1-X GaXSe2 (CIGS)/ZnO solar cells with a total area efficiency of 13.7% are reported. These nominally 1 cm2 cells are prepared by elemental coevaporation of the selenide material, chemical deposition of a thin (20-30 nm) CdZnS layer and RF magnetron sputtering of the ZnO transparent conductive film. The Ga and Zn contents were measured to be 26% and 20%, respectively. The authors attribute the improved performance over their previous CIGS cells to a slightly higher Ga concentration and to the preparation of ZnO films with lower optical losses
