| Abstract: | Graphene dispersions in low-boiling-point green solvents have wide applications in coatings,conducting inks,batteries,electronics and solar cells.Two three-dimensional(3D)cathode interfacial materials(CIMs)(1,3,5,7,9,11,13,15-octa-(9-bis(30-(N,N-dimethylamino)propyl)-2,7-fluorene)-vinylpentacyclo-octasiloxane)(POSSFN)and(1,3,5,7-tetra-(9-bis(30-(N,N-dimethylamino)propyl)-2,7-fluorene)-adamantane)(ADMAFN)are excellent surfactants for dispersing graphene in ethanol at the concentration of 0.97–1.18 mg mL−1,in agreement with their calculated large adsorption energies on graphene.The results of electron spin resonance,Raman,scanning Kelvin probe microscopy and X-ray photoelectron spectroscopy measurements indicate that the amino groups could n-dope graphene or form dipole interaction with graphene.The two 3D-surfactant-based graphene composites(POSSFN-G and ADMAFN-G)can work as high-performance CIMs in organic solar cells(OSCs),which improve the power conversion efficiency(PCE)of the OSCs based on PM6:Y6 to 15.9%–16.1%.ADMAFN forms dipole interaction with graphene in ADMAFN-G and the composite CIM delivers high PCE of 16.11%in the OSCs,while POSSFN forms n-doped composition with graphene in POSSFN-G which works well as thicker CIM film in the OSCs. |
