Viable solutions for solar cells: BASF offers a broad range of high-purity ionic liquids that can serve as electrolytes. They are used in dye-sensitized solar cells, for example. Specifically adapted to the electrode and dye system, the ionic liquids are in this case key to ensuring that the solar cell will generate power in a reliable and stable manner.
Solar cells based on this technology can be manufactured in a much more cost-efficient manner that conventional silicon-based cells. They also are sensitive to far more of the visible spectrum of light, so that they can use all sorts of light sources, even at relatively low levels of light intensity. They are therefore highly suitable for portable applications such as mobile phone chargers in regions that do not have a universal power supply grid.
High quality even on industrial scale: BASF sells its broad range of ionic liquids under the Basionics brand. Around the world, the company offers lab-scale as well as industrial-scale quantities, guaranteeing high levels of flexibility and reliability of delivery. The exceptionally high quality of these BASF products is ensured by continuous optimization of manufacturing processes.
Customized solutions: BASF looks back on a full six years of experience in ionic liquids, a fairly recent field that promises good prospects for development. Its broad base of expertise allows BASF to customize its ionic liquids to meet specific requirements. BASF supports customers in all steps, from the selection of the suitable ionic liquid right down to its commercial use. The company will also develop new ionic liquids on request.
Interesting combination of properties: Ionic liquids are salts similar to common salt as we use it every day. Their chemical structure makes them different, however: they are liquid even at low temperatures. Since their functions show the typical characteristics of salts and liquids too, the overall profile of properties that is obtained cannot be achieved by any other material.
Ionic liquids are non-flammable; they feature thermal and mechanical stability as well as electric conductivity. This interesting combination of properties opens the road to a wide range of new applications.
