Hollow TiO 2 hemispheres for application in dye‐sensitized solar cells are prepared by means of rf‐sputtering onto colloidal templated substrates. After removing the organic templates by thermal decomposition, quasi‐ordered networks of hollow TiO 2 hemispheres were formed. This approach should open up new opportunities for processing material architectures with high surface activity and effective charge transport for high performance photovoltaic and photoelectrochemical cells.
