The transfer from poly-3hexylthiophene (P3HT) based fullerene free organic photovoltaic (OPV) lab cells with IDTBR (rhodanine-benzothiadiazole-coupled indacenodithiophene) as acceptor material to fully solution processed roll-to-roll (R2R) compatible modules is reported. The developed R2R process is fully compatible with industrial requirements as it uses exclusively non-hazardous solvents. The combination of optimized ink formulation, module layout, and processing affords efficiencies of 5% on 60 cm total module area.
