inkjet head with a motorized xyz stage, a fiducial camera for the substrate alignment and a drop watcher camera to control the drop shape. The photoactive layer consists of P3HT blended with fullerene PCBM in a 1:1 weight ratio were dissolved in Tetralene and oDCB/ mesitylene solvent mixtures. On top of the active layer, an additional CaAg top electrode was deposited by physical vapor deposition to complete the bulk heterojunction solar cell. Before the evaporation of the top electrode, the devices were subjected to a thermal treatment at 140°C for 10 min. For efficiency evaluation the device area was defined by the overlap between the underlying ITO and the top electrode. Solar cells with an active area of typically 20 mm 2 and up to 1 cm 2 were studied. The devices’ current density-voltage ( J–V ) characteristics were assessed with a source measurement unit SMU 2400 from Keithley under nitrogen atmosphere. For illumination a Steuernagel Solarsimulator was used providing an AM 1.5G spectra at 0.1W cm –2 . The high-resolution atomic force microscope consists of a cantilever with a sharp tip at its end to scan the surface of the sample. The probe was based on silicon nitride with a radius of curvature in the nanometer scale.

- How the structural deviations on the backbone of conjugated polymers influence their optoelectronic properties and photovoltaic performance (2011, methodology): “While it was shown hat when the molecular weight of rrP3HT ranged between 0,000 < Mn < 75,000 higher efficiencies are exhibited due o the ideal morphology formed, the role of regioregularty has been shown to be critical in order to achieve the rP3HT crystallinity during the annealing processing step”
- Airbrush spray-coating of polymer bulk-heterojunction solar cells (2010, background): “Solar cells are built up in a multilayer structure, which can be formed utilizing different deposition techniques like drop-casting, spin-coating, doctor-blading, brush-painting, screen and ink-jet printing [9–15].”
