The morphology of mesoporous TiO2 films plays an important role in the operation of a DSSC. For example, the energy conversion efficiency of DSSCs with well-organized mesoporous TiO2 films is much higher than those with traditional films possessing a random morphology. We provide the first report on the successful synthesis of well-organized mesoporous TiO2 films templated by an organized graft copolymer as a structure directing agent. Well-organized mesoporous TiO2 films with excellent channel connectivities were developed via the sol gel process using an organized PVC-g-POEM graft copolymer synthesized by one-pot ATRP. The careful adjustment of copolymer composition and solvent affinity using a THF/H2O/HCl mixture was used to systematically vary the material structure. We also introduced solid-state polymerizable conductive monomer with good conductivity and penetration to photoelectrode to iodine-free solid-state DSSCs, which involves easily accessible and widely applicable fabrication method. A conducting polymer as a hole transporting material is effectively penetrable into the TiO2 pores and polymerizable by heating at mild temperatures. The fabricated DSSCs exhibited the highest energy conversion efficiency of 5.4 % in N719 dye.
