چکیده
DSSCs have reached certified efficiency of 11.9% and device 14.3% using I−/I3− or Co(ii/iii) redox shuttles. But, they many constraints Cu(i/ii) electrolytes are found to be best alternatives the has crossed 30% under low light conditions, potential applications in Internet things.

Ionic liquid electrolytes for dye-sensitized solar cells.
The potential of room-temperature molten salts (ionic liquids) as solvents for electrolytes for dye-sensitized solar cells has been investigated during the last decade. The non-volatility, good solvent properties and high electrochemical stability of ionic liquids make them attractive solvents in contrast to volatile organic solvents. Despite this, the relatively high viscosity of ionic liquids...
متن کاملIonic Liquid Based Electrolytes for Dye-Sensitized Solar Cells
1.1 New type of solar cell: dye-sensitized solar cells (DSSCs) The rising price of fossil fuels, together with their rapid depletion and the pollution caused by their combustion, is forcing us to find sources of clean renewable energy. Fortunately, the supply of energy from the sun to the earth is gigantic, i.e., 3 × 1024 joule a year or about ten thousand times more than what mankind consumes ...
متن کاملHighly efficient catalysts for Co(II/III) redox couples in dye-sensitized solar cells.
We developed several low-cost catalysts with high catalytic activity, which were used as counter electrodes in dye-sensitized solar cells (DSCs). They showed higher efficiencies than that of Pt. The efficiencies were improved by 18-42% for the DSCs composed of active carbon, niobium dioxide, ordered mesoporous carbon and commercial titanium carbide.
متن کاملDye-Sensitized Solar Cells Based on Polymer Electrolytes
Dye-sensitized solar cells (DSSCs) using organic liquid electrolytes have received significant attention because of their low production cost, simple structure and high power conversion efficiency [1-5]. Recently, the power conversion efficiencies of DSSCs using Ruthenium complex dyes, liquid electrolytes, and Pt counter electrode have reached 10.4 % (100 mW/cm2, AM 1.5) by Grätzel group [6]. H...
متن کاملDye molecules in electrolytes: new approach for suppression of dye-desorption in dye-sensitized solar cells
The widespread commercialization of dye-sensitized solar cells remains limited because of the poor long-term stability. We report on the influence of dye-molecules added in liquid electrolyte on long-term stability of dye-sensitized solar cells. Dye-desorption from the TiO2 surface during long-term cycling is one of the decisive factors that degrade photocurrent densities of devices which in tu...
