Fig. 15From: Effect of Gold Nanoparticle Distribution in TiO2 on the Optical and Electrical Characteristics of Dye-Sensitized Solar CellsIPCE spectra of the DSSCs with varying the layer number and the density of GNPs. The GNP layers of P1, P2, and P3 were formed at positions of 1.1, 2.2, and 3.3 μm from the TCO surface, respectively. The numbering in the legend with the format (P1-P2-P3) shows the density of GNPs (μg/cm2) at each positionBack to article page
