A new series of zinc porphyrins (denoted ad LD4-OR4, LWT16, LWT18 and LWT27) were synthesized for dye-sensitized solar cells (DSSCs). The resultsshowed thatLWT18had the best photovoltaic performance in the series, withJSC = 19.98mA cm-2, VOC = 706mV, FF = 0.71, η= 10.20%. Compared with our previous dyes, using commercially available by TiO2 paste, LWT18 can achieve efficiencies above 10%.
