Figure 5. Electric performance evaluations of the plasmonic wafer cells.

(a) The Voc and Jsc of the rear plasmonic enhanced wafer cells as a function of the wafer thickness. The dash line shows the Jsc of the 180 μm standard wafer cells for reference. (b) The Eff of the rear plasmonic enhanced cells, referenced to the standard cells. The normalized efficiency (to the 180 μm standard wafer cells) is shown in the right axis.
