- Abstract
- We have designed and synthesised novel zinc porphyrin dyes that have a D-pi-A system based on porphyrin derivatives containing a carbazole linked triphenylamine (TPA) electron-donating group as the second electron donor and a meso-substituted phenyl carboxyl anchoring group attached at the meso position of the porphyrin ring, yielding push-pull porphyrins as the most efficient green dye for DSSC applications. Under photovoltaic performance measurements, a maximum photon-to-electron conversion efficiency of 5.01% was achieved with the DSSC based on the dye HKK-Por1 (Jsc = 10.7 mA/cm(2), V(OC) = 0.67 V, FF = 0.70) under AM1.5 irradiation (100 mW/cm(2)).
