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 J SC , V OC , and FF values of 10.65 mA/cm 2 , 0.67 V, and 0.71, respectively.
