The device structure is FTO/nc-TiO2/Dye/I-/I-3(-)/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/cm(2)). 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; eta = 0.91%.en10.1051/epjap:2007086info:eu-repo/semantics/closedAccessArticle383227230WOS:000247671500006N/AQ3
