Abstract

We report the characterization of 1,8-naphthalene benzimidazole comprising carboxyl group. We have fabricated dye-sensitized nanocrystalline TiO2 solar cell (DSSC) based on naphthalene benzimidazole dye. The device structure is FTO/nc-TiO2/Dye/I/I3 /Pt/ FTO. We calculated the E HOMO and E LUMO levels of this new dye by using cyclic voltammetry measurement. The E LUMO level of naphthalene benzimidazole is 3.2 eV. This value is higher than the conduction band of TiO2. Electrons can be injected to the conduction band of TiO2. The current-voltage (I-V) characteristic of cell was measured under simulated AM 1.5 illumination (100 mW/cm2). We obtained the open circuit voltage; V oc = 0.344 V, short circuit current density; I sc = 5.93 mA cm-2, filling factor; FF = 0.45, power conversion efficiency; η = 0.91%.
