| Abstract: | A novel dihydrophenazine-based organic di-anchoring dye DK-11 was synthesized by utilizing a simple synthetic protocol. The dye was characterized by optical and electrochemical studies and used as a sensitizer for dye-sensitized solar cell. The proposed butterfly structure was supported by IR experiments which ensured the binding of both carboxylic acid units on the semiconductor surface. Using the dye DK-11 , the device generated an efficiency of 5.07% with JSC, VOC, and FF values of 10.65 mA/cm2, 0.67 V, and 0.71, respectively. |
