%X Ultrafast heterogeneous electron transfer, including direct transition from the surface attached molecule into the semiconductor band states, is introduced with the focus on a system of perylene on TiO2. The contribution of intramolecule transition and direct electron transition to the absorption spectra are analysed theoretically. By comparing with the intramolecule transition contributions, the ultrafast direct transition contributions to the absorption spectra with different physical parameters are analysed.
