Dye-sensitized solar cells (DSSCs) were fabricated by using porous ZnO electrodes derived from home-made ZnO nanoparticles. Electrochemical impedance spectra and open-circuit photovoltage decay curves measurements were performed to investigate the photoelectrochemical characteristics of ZnO films annealed at different temperatures. The experimental results indicate that the effects of the bulk traps...
In this paper, the synthesis of 1-hexyl-3-methylbenzimidazolium iodide (HMBI) and 1-hexyl-3-propylbenzimidazolium iodide (HPBI) was developed by quaternization reaction of 1-hexylbenzimidazole and alkyl iodide under solvent-free condition using Teflon-lined, stainless autoclaves. Their thermal properties were measured on the thermo gravimetric analysis and differential scanning calorimeter. The influence...
