Abstract
Two novel triarylamine- and triazine-cored porphyrin dimers were synthesized and investigated for their potential in dye-sensitized solar cells (DSSCs). Based on cyclic voltammetric analysis, highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels of the target porphyrins were found to be in an appropriate range in the TiO2-based DSSC systems. The device studies indicated the photovoltaic effects in the DSSCs based on both materials and the significant effect of their core units on the photovoltaic conversion efficiencies of the devices.
