In the previous sections, we have discussed electron transfer reactions between optically excited molecules and semiconductor electrodes. The question arises whether the opposite effect, the production of an excited state by electron transfer, is also possible. In principle it can be realized if we select a semiconductor, the conduction band (c.b.) of which is located above the energy level of the excited species [ f(M /M )]. The reaction process is then given by... 

In the previous section discussion has centered on electrode reactions stimulated by light absorption in the semiconductor electrode. In the present section, electron transfer processes between electrodes and excited molecules will be treated. In order to avoid any light absorption by the electrode itself, only large band gap semiconductors can be used.
