The local efficiency of hybrid ZnO-nanorods/C/ZnPc:C/MoO/Ag solar cells, with different nanorods length has been investigated by scanning near-field optical microscopy. Simultaneous spatially resolved measurements of topography and photocurrent suggest a waveguide effect enhancement of the local photocurrent. This interpretation is supported by finite element method simulations of the light propagation in the solar cell.
