Titania porous network structure for solar cell application

The porous titanium dioxide network structure with adjustable average pore size were prepared. The different pore sizes were obtained by controlling the titanium precursor concentration. The porous anatase titania network structure with high surface area is thermally stable and uniform over the whole sample area. The use of these structures in organic solar cells yielded considerable improvements in the short circuit currents compared to previous reports on TiO/sub 2//polymer solar cells.
