• electrons, they cannot be easily transferred to solar cells made of oxides with strongly correlated electrons. Another reason to introduce a second diode is given by Giebink et al. [38][39]. They introduce a second diode in organic systems in order to take the voltage dependence of different charge carrier

• recombination mechanisms into account. Here, hole or electron-type polarons can change their character from trapped to mobile, respectively. In our model system, the last effect is not taken into account, since the mobile carriers in the STNO are always electrons for all voltage ranges. Even if values for the

The NWs are too large in diameter for a quantum confinement induced energy shift in the band gap. Nevertheless, NW PL is readily observed, indicating that efficient carrier recombination is

• ]. The design of anisotropically shaped semiconductors is limited since the band-edge luminescence is further reduced due to a higher surface-to-volume ratio and the increased carrier delocalization lowering the probability of a radiative carrier recombination [10], but their major drawback, the
