At the Daresbury Laboratory Synchrotron Radiation Source X-ray photoemission spectroscopy (XPS) and ultraviolet photoemission spectroscopy (UPS) were used to investigate the interfaces of the dye sensitised solid state solar cell. Single crystal (101), nanoparticulate and mesoporous titanium dioxide (TiOz) surfaces were examined using valence band and core level spectra to understand the electronic interactions at heterointerfaces with copper iodide (Cul) and bi-isonicotinic acid (BINA). Photoemission spectra of the anatase (101) single crystal TiO₂ nanoparticulate Ti0₂ surface show their electronic structures are similar but differences exist due to the number of defect states and the differences in band gap due to quantum confinement.
