Solution Processed Silver Nanoparticles in Dye-Sensitized Solar Cells
Figure 3
(a–c) The absorption of the (a) and (b) NPs (without shell) and Ag/TiO2 core/shell NPs (c) located within the undyed TiO2 layer on microscope glass substrate heat treated at different temperatures. The absorption of bare TiO2 layer (black full line) and the bare TiO2 layer covered with a thin “shell” TiO2 layer (black dashed line) on a microscope glass substrate are shown for the reference. (d) The same as (c) but dyed porous TiO2 layers.
