Abstract [en]

Copper Biquinoline coordination complexes were synthesised and characterisedin terms of optical and energetical properties for application as solid statehole transport materials (HTM) in solid state dye-sensitised and perovskitesolar cells (ssDSSC and PSC). The energy levels of two complexes were found to match the HOMO and LUMO level and the conduction and valenceband of the sensitisers and perovskite absorber, respectively, providing a slight overpotential for hole injection and potential barrier for electrons. Despite matching energetics incorporation of the materials in a ssDSSC did not yet result in a working device. Photoinduced absorption spectroscopy(PIA) revealed that the dyes (LEG4 and SM315) are not regenerated by the materials. Photoluminescence (PL) measurements on a perovskite/HTM sample showed extraordinately strong quenching for one of the complexes, indicating effective charge separation at the interface. Application in a PSC yielded efficiencies exceeding 10%, showing the general potential of this new material.
