Figure 1

(a) The schematic diagrams of a non-collinear optical parametric amplifier (NOPA) and a 400 nm pump-ultrabroadband probe system. (b) The schematic presentation of various plasmonic energy transfer processes between Au-NPs and CIGS in plasmonic CIGS thin film. Also shown in the diagram are the excitation and recombination paths in CIGS.
