Ionic 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 کاملIonic 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 کاملBenzimidazolyl functionalized ionic liquids as an additive for high performance dye-sensitized solar cells.
Benzimidazolyl functionalized ionic liquids were synthesized and applied as additives for dye-sensitized solar cells. The fabricated devices show an overall power conversion efficiency of ~7.79% under AM 1.5 radiation (50 mW cm(-2)), and an excellent long-term stability.
متن کاملThe Role of Confined Water in Ionic Liquid Electrolytes for Dye-Sensitized Solar Cells.
Ionic liquids (ILs) provide an attractive medium for various chemical and redox reactions, where they are generally regarded as hydrophobic. However, Seddon et al. discovered that 4-10 wt % water absorbs into ILs that contain bulky anions, and Cammarata et al. found that the molecular state of water in ILs is dramatically different from that of bulk liquid water or that of water vapor. To deter...
متن کاملSolid-State Ionic Liquid Based Electrolytes for Dye-Sensitized Solar Cells
The increasing global need for energy coupled with the depletion of easily accessible, hence cheap, fossil fuel reserves, poses a serious threat to the human global economy in the near future [1]. Considering in addition the harmful ecological impact of conventional energy sources, it becomes obvious that development of clean alternative energy sources is a neces‐ sity [2, 3]. Best renewable en...
