We fabricated Three-Dimensional (3D) TiO2 structures for Dye Sensitized Solar cells (DSSC) via interference lithography (IL) followed by TiO2 infiltration. After TiO2 was infiltrated into 3D nano-structured polymer templates, the polymer templates were removed at high temperature (500℃) for 3D TiO2 structures. 3D structures with a specific geometry offer many advantages, such as high surface-to-volume ratio, good mechanical strength yet low density, as well as superior properties in photonic and phononic devices.These properties have a great potential in light conversion efficiency and light- trapping effect of 3D DSSC. |
