|Abstract: ||hybrid solar cells based on metal oxides in combination with semiconducting polymers are offering potential as future low-cost and upscalable photovoltaics. However, the use of toxic solvents such as chlorobenzene, chloroform or toluene for the polymer processing, remains a drawback. In an effort to attain the summit of environmentally friendly device fabrication, in this work, full water-based hybrid solar cells are fabricated. Metal oxide nanorod arrays, prepared via an aqueous synthesis are used as electron acceptors, while the need for toxic solvents in polymer processing is circumvented by replacing the widely used replacingthewidelyusedpoly(3-hexylthiophene-2,5-diyl)(P3HT)withitswater-solublecounterpart
poly(3-(potassium-4-hexanoate)thiophene-2,5-diyl)(P3PHT). Comparing two deposition techniques and two metal oxides leads to a promising efficiency of 0.2% for drop casted P3PHT in combination with rutile TiO2 nanorod arrays, and demonstrates the possibility to develop fully 'green' nanorod based hybrid solar cells.|
