Figure 2From: Solid-state dye-sensitized solar cells based on ZnO nanoparticle and nanorod array hybrid photoanodes Schematics and FE-SEM images for solid-state DSSCs with different photoanode morphologies. Schematics of device based on (a) nanorod array photoanode (sample 1), (b) nanorod array photoanode with nanoparticles partially filling the interstices (sample 2), (c) nanorod array photoanode with nanoparticles fully filling the interstices (sample 3), (d) nanoparticle photoanode (sample 4). Blue rectangles represent ZnO nanorods, blue dots represent ZnO nanoparticles, red dots represent N3 dyes, the gray film represents P3HT, and the yellow film represents gold. FE-SEM images of photoanodes for (e) sample 1, (f) sample 2, (g) sample 3, and (h) sample 4. The scale bar is 100 nm for all SEM images.Back to article page
