Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: A novel method was developed to convert the electro-catalytically inactive commercial WO 3  and SnO 2  into high efficient WO 3−x  and SnO 2−x  counter electrodes for dye sensitized solar cells (DSSs) to replace Pt. Both WO 3  and SnO 2  was treated with Urea with different Urea mass ratio concentrations and annealed under N 2  environment at 500°C. The energy conversion efficiency (PEC) was significantly improved by urea treatment with 8.57% compared to 2.91 % for non-treated CE in case of WO 3  and increases from 2.76 % for non-treated CE to 8.7 % after urea treatment in case of SnO 2 . All other characterizations performed for urea treated WO 3  and SnO 2  support the hypothesis of creating oxygen vacancies inside the metal oxides by the treatment. These oxygen vacancies facilitate the redox process in iodide/trioxide electrolyte. The density of these oxygen vacancies could be controlled by controlling the urea concentration during the treatment.
