제목 Fabrication of macroporous photoelectrodesby colloidal templating methods
초록 In dye-sensitized solar cells, TiO2 nanocrystalline particles have been investigated extensively as a key material. In this study, we present a new strategy to fabricate macroporous photoelectrodes using polystyrene(PS) colloidal templating methods both at high temperature (>400oC) and at low temperature (150oC>). Polymeric colloidal structures could be removed by thermal sintering or chemical treatment. This mesoporous structure provides the large empty space leading to the easy infiltration of quasi-solid state electrolytes and has additional light harvesting effect. A major advantage of this colloidal array template method is that the pore size and its distribution within TiO2 photoelectrodes are determined by those of latex beads, which can be controlled easily. These materials may have promising potentials for future applications of membrane, sensor and so on as well as solar cells.
