Study of Dye-Sensitized Solar Cells by Scanning Electron Micrograph Observation and Thickness Optimization of Porous Electrodes
Figure 4
Cross-sectional SEM images of a porous double-layered TiO2 electrode polished with an Ar-ion beam (nanocrystalline-TiO2 layer: 14 m thick; submicron crystalline-TiO2 layer: 5 m thick). (a) is the most zoomed-out image. White dotted quadrangles show the zoomed-in area for the other images.
