Due to a high surface to volume ratio and their bicontinuous morphology, foam-like network nanostructures are receiving increasing interest in photovoltaic applications. Controlling the pore size is crucial for devices, such as dye-sensitized solar cells (DSSCs) and solid state DSSCs. In this study, spray coating is used as deposition method since it is allowing for scaling-up to large scale production. A block copolymer template assisted sol-gel process is used to form the nanostructured titania films. The structure evolution is probed with in situ GISAXS during the spray coating process. The morphology of the sprayed films is characterized with SEM and optical microscopy. The crystalline structure of the titian films is probed with XRD. The optical properties and photoluminescence emission state of the mesoporous titania films are probed by UV vis and photoluminescence, respectively.
