Schematic illustrations and electron microscopy images of TiO2 structures.
(a) Schematic illustration of the fabrication process for the hybrid TiO2 structure (H-TiO2). (b) Top view SEM image of st-TIO for photon trapping. The inset shows transmittance electron microscopy (TEM) image of the mesoporous surface textured-TIO (st-TIO). (c) Top view SEM image of the patterned mesoporous TiO2 layer for anti-reflection. The inset shows the close-up image of the P25 particles. (d) Cross-sectional SEM image of H-TiO2. (e) Schematic illustration of pathway of incoming light engineered by H-TiO2 compared with the case of P25.
