Abstract

Indoline dye D-1 was successfully applied as a cosensitizer for improving the spectral response of black dye in dye-sensitized solar cells (DSCs). It was observed that D-1 effectively increases the short-circuit photocurrent by offsetting the competitive light absorption by I / I 3 - electrolyte in the wavelength region 350-500 nm when adsorbed on the TiOnanocrystaline films in a mix dye system. The DSCs containing the D-1 and black dye achieved a power conversion efficiency of 9.80 with higher short-circuit photocurrent of 19.54 mA/cm 2 compared to the system of black dye without cosensitization under standard AM 1.5 sunlight.
