Hybrid solar cells have attracted great attention due to the advantages of their short payback time, high stability and flexibility, which results from the combination of inorganic and organic materials. As photoanodes, mesoporous ZnO with a large surface area were widely employed to host the light-harvesting dyes and the organic molecular hole-transporters. For the synthesis of nanostructured ZnO, diblock copolymer assisted sol-gel approach has been corroborated by countless reports to be powerful in morphology tunability. The amphiphilic diblock copolymer assisted sol gel method and suitable printing parameters are used to fabricate nanostructured ZnO films. In situ grazing-incidence small-angle X-ray scattering (GISAXS) monitors continuously the inner film morphology in a destruction free manner. Based on printed nanostructured ZnO films, hybrid dye-sensitized solar cells are prepared and photovoltaic performance is investigated.
