A common production method for organic photovoltaic (OPV) modules consists in roll-to-roll printing on PET foils . A promising future application is the integration of OPV modules into window panes . Due to the high design freedom of inkjet printing, OPV modules can be directly printed onto the panes . For large area printing, homogenous OPV films are crucial . The solvents used in the ink formulation need to be non-destructive for the inkjet print heads . Moreover, sufficiently slow drying solvents are needed for OPV inkjet printing  to avoid the so-called coffee ring effect, leading to a non-uniform printed layer.
