Abstract
We describe the optimization of bulk heterojunction type photovoltaic devices from blends of ZnO nanoparticles and conjugated polymers. The photovoltaic effect of these devices depends on the choice of solvent, the amount of ZnO, and the thickness of the active blend layer. Optimized solar cells have an estimated AM1.5 performance of 1.6%. Incident photon to current conversion efficiencies (IPCE) show that up to 40% of the incident photons can be collected as charges. At high light intensities the performance of the cell drops, due to a decreasing fill factor (FF).
