The preparation of electronic devices from solution receives a lot of attention nowadays due to the low cost potential. One approach is an organic--inorganic hybrid system for applications in solar cells. For a deeper understanding of these material combinations, we examine the charge transport in the organic semiconductor poly(3-hexylthiophene) and the inorganic Al-doped zinc oxide nanoparticles, respectively. We present the charge carrier mobility in dependence of the charge carrier densities and temperature measured on field effect devices. Contact effects due to the workfunction of the injecting electrodes are taken into account. We survey the properties of the transport in these disordered systems, organic and inorganic, in the high carrier concentration regime. Those will be discussed with respect to the underlying transport models.
