    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photoelectron spectroscopy; X-ray absorption spectroscopy; organic semiconductor; oxides; adsorption; dye sensitization; electronic structure; charge transfer;

    Sammanfattning : The photosensitive molecule adsorption on titanium dioxide (TiO2) forms the so-called “dye sensitized TiO2” system, a typical organic/oxide heterojunction, which is of great interest in catalysis and energy applications, e.g. dye-sensitized solar cell (DSSC). Traditionally, the transition metal complex dyes are the focus of the study. LÄS MER
