Περίληψη:	This study presents the synthesis and the characterization of anew covalent zinc porphyrin-fullerene (ZnP-C 60) dyad, featuringa π-conjugated bridge to link the donor (ZnP) and the acceptor(C60 ). This system, along with a couple more reference com-pounds, namely ZnP-3DoH-COOH and C60trZnPCOOH, is testedas photosensitizers in p-type dye-sensitized solar cells (p-DSSCs).Photophysical studies, including absorption and emission spec-troscopy, reveal strong electronic communication between theporphyrin core and the fullerene unit, corroborated by theoreticalcalculations demonstrating efficient electron transfer from thedonor to the acceptor. Electrochemical measurements, supportedby theoretical insights, confirm that the highest occupiedmolecular orbital (HOMO) and lowest unoccupied molecularorbital(LUMO) energy levels of the C 60 -3PV-ZnP-2DoH-COOHdyad are well aligned for effective integration into NiO-basedDSSCs. Notably, photovoltaic performance measurements showthat solar cells sensitized with the covalent dyad exhibit signifi-cantly enhanced efficiencies compared with those using the ref-erence compounds and other “ZnP-Acceptor” dyads. Thesefindings highlight the potential of covalent ZnPor-C 60 assembliesin advancing the design of high-performance p-type DSSCs.
