Urea Pre-treatment of N2-annealed Transition Metal Oxides for Low Cost and Efficient Counter Electrodes in Dye-sensitized Solar Cell
… Platinum (Pt) was used as a catalyst in the counter electrode for DSSCs. Metal oxides have been used as an alternative material to Pt. The introduction of oxygen vacancies inside metal oxides helps to facilitate electron transport to the electrolyte to enhance the reduction process of …

Transparent Platinum Counter Electrode for Building Integrated Dye-sensitized Solar Cells
… method for fabrication of highly transparent Pt counter electrodes (CE) has been developed based on spray deposition of Pt nanoparticles (Pt-NPs) on hot substrates. The platinum consumption hence the cost of the counter electrode was reduced over 86%, compared to conventional Pt counter electrode …
