All lined up: One-dimensional TiO2 nanorods provide an aligned architecture and spaces between them that allows denser packing of PbS colloidal quantum dots on their surfaces as well as more effective infiltration of the poly-3-hexylthiophene hole transport materials. Thus, the fill factor is significantly improved in comparison to conventional mesoscopic TiO2 nanoparticle-based solar cells.
