Laser-ablated titania nanoparticles for aqueous processed hybrid solar cells

Titania nanoparticles are produced by laser ablation in liquid in order to initiate functionalization of titania with the polymer for the active layer. By combining these titania nanoparticles and water-soluble poly[3-(potassium-6-hexanoate)thiophene-2,5-diyl] (P3P6T) hybrid solar cells are realized.Financial support by TUM.solar in the frame of the Bavarian Collaborative Research Project “Solar technologies go Hybrid” (SolTec), by the GreenTech Initiative (Interface Science for Photovoltaics–ISPV) of the EuroTech Universities and by the Nanosystems Initiative Munich (NIM) is acknowledged.
