摘要

Hybrid photovoltaic devices based on heterojunctions of nano-structured metal oxides and conjugated polymers are attracting great scientific interest as low-cost and up-scalable alternatives for conventional photovoltaics. Although dye-sensitized solar cells are still the most efficient metal oxide based solar cells, the presence of a liquid electrolyte induces leakage and corrosion which harms the long term performance and stability. The introduction of solid state hybrid solar cells offers an alternative approach to overcome these drawbacks by replacing both the dye and the electrolyte by a single polymer that acts as a hole conductor and absorber. Until now, hybrid solar cells based on ZnO nanorods and poly-(3-hexylthiophene-2,5-diyl) (P3HT) have reached maximum efficiencies up to 0.55%. Here, we demonstrate a significantly improved efficiency of 0.74% ± 0.02% for hydrothermally grown ZnO nanorods and P3HT. We show that tuning the crystalline quality of the polymer in combination with optimized hole and electron blocking layers are mainly responsible for the achieved progress.
