Hybrid solar cells based on metal oxides and water-soluble polythiophenes — •Jiabin Gui1, Volker Körstgens1, Klara Stallhofer2, Hristo Iglev2, Reinhard Kienberger2, and Peter Müller-Buschbaum1 — 1TU München, Physik-Department, LS Funktionelle Materialien, 85748 Garching — 2TU München, Physik-Department, LS Laser und Röntgenphysik, 85748 Garching
Environmentally friendly processing of hybrid solar cells with the solvent water is feasible with an active layer consisting of laser-ablated metal oxides and a water-soluble polythiophene [1]. Zinc oxide and titanium dioxide particles are processed with laser ablation in water. The obtained nanoparticles are investigated regarding the size distribution and crystallinity. Spray-deposition as a cost-effective preparation method has been utilized as technique to produce films of the laser-ablated nanoparticles, the active layers including polythiophenes and the corresponding hybrid solar cells. Films have been characterized with optical and spectroscopic methods as well as with x-ray characterization techniques. The influence of differences of bandgap, crystallinity and mesoscale morphology on the photovoltaic performance of the obtained devices is discussed. [1] Körstgens et al., Nanoscale 7, 2900 (2015).
