Abstract:
Red-kinked current-voltage characteristics in silver nanowire transparent electrode based Cu(In,Ga)Se2 solar cells have been reported [1-3]. The author has recently revealed that the buffer/window interfacial defects cause the generation of red-kinked current-voltage characteristics in the solar cells [1]. This article provides the dataset regarding the red-kink for Cu(In,Ga)Se2 solar cells as a function of the donor density in n-type window and CdS buffer/window interfacial defect density. The data were obtained by the simulation for Cu(In,Ga)Se2 solar cells using SCAPS-1D. The data include current density-voltage curves, fill factor, open-circuit voltage, short-circuit current density, and efficiency in the solar cells, and energy band bending in the Cu(In,Ga)Se2 layer.
