Abstract :
Randomly microphase-separated graft copolymers have been self-reorganized so as to exhibit a micellar structure with excellent connectivity upon tuning the solvent affinity. These copolymers are used as a structure-directing agent for organized mesoporous TiO2 films with non grain boundaries, leading to enhanced solar conversion efficiency of dye-sensitized solar cells.
