Results confirm that the photovoltaic performance is strongly influenced by both, the individual optoelectronic properties of ZnPcs and the aggregation of these tetrapyrrolic semiconductors in the solid thin film. The optimized devices exhibit PCE of 15.5% when using tetra-5-hexyl-2,2′-bisthiophene substituted ZnPcs, 13.3% for tetra-tert-butyl ZnPc, and a record 17.5% for tetra-5-hexylthiophene-based analogue under standard global 100 mW cm−2 AM 1.5G illumination. These results boost up the potential of solution-processed ZnPc derivatives as stable and economic hole-transport materials for large-scale applications, opening new frontiers toward a realistic, efficient, and inexpensive energy production.
