Hollow TiO2 Hemispheres Obtained by Colloidal Templating for Application in Dye-Sensitized Solar Cells

Hollow TiO2 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 TiO2 hemispheres were formed. This approach should open up...

description Hollow TiO2 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 TiO2 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.
