title: Spiro-fluorene based 3D donor towards efficient organic photovoltaics.
abstract: A novel 3D donor material (SF8TBT) based on spiro-fluorene has been developed. Compared with the corresponding 1D linear molecule, the OPVs of this 3D donor exhibited power conversion efficiencies of 4.82%, much higher than that of 1D small molecules (1.69%).
