Lyotropic Liquid-Crystalline Mesophase of Lithium Triflate−Nonionic Surfactant as Gel Electrolyte for Graphene Optical Modulator
Lithium salt (noncoordinating anions, such as lithium triflate (Ltf)) gel electrolytes may be key for the practical use of electrochemical devices. We introduce a new lyotropic liquid-crystalline (LLC) mesophase using Ltf, a small amount of water (as low as 1.3 water per Ltf), and nonionic surfactant (C18H37(OCH2CH2)10OH, C18E10). The LLC phase forms over a broad range of Ltf/C18E10 mole ratios...
متن کاملA new, highly conductive, lithium salt/nonionic surfactant, lyotropic liquid-crystalline mesophase and its application.
Highly conductive electrolyte materials are an essential part of many electrochemical systems, such as fuel cells, solar cells, batteries, electrochromic devices, and next-generation renewable-energy sources. The growing diversity in batteries and electrochemical cells increases the demand for novel electrolyte materials. For instance, in solar-cell applications, an electrolyte material with hi...
متن کاملEffect of Hydroquinone Dderivatives in Electrolytes on Dye-Sensitized Solar Cell Performance
New kinds of hydroquinone derivatives were synthesized and along with a azo dye applied as additives in the iodide/iodine redox electrolyte for dye-sensitized solar cells and their effect on the short-circuit photocurrent of dye sensitized solar cells was investigated. Addition of 0.05 M a hydroquinone derivative in the electrolyte comprising 0.5 M 1-methyl-3-propylimidazolium iodide (MPII) and...
متن کاملQuasi solid state dye - sensitized solar cells based on polyvinyl alcohol ( PVA ) electrolytes containing I − / I − 3 redox couple
Quasi solid state dye-sensitized solar cells (DSSCs) have been fabricated with electrolytes containing I−/I3 redox couple using 80 % hydrolyzed polyvinyl alcohol (PVA) doped with potassium iodide (KI) and a mixture of potassium iodide and tetrapropyl ammonium iodide (Pr4NI) salts. The quasi solid state gel polymer electrolytes were prepared using 1:1 ethylene carbonate (EC):propylene carbonate ...
متن کاملDye-sensitized solar cells based on cobalt-containing room temperature ionic liquid redox shuttles
An imidazolium-based co-containing room temperature ionic liquid, bis(3-butyl-1-methylimidazolium) tetraisothiocyanato cobalt [BMI]2[Co(NCS)4], was synthesized and characterized. The prepared [BMI]2[Co(NCS)4]/1-propyl-3-methylimidazolium iodine (PMII) hybrid redox couple showed higher redox potential than that of the iodide/triiodide (I /I3 ) redox couple. The resultant dye-sensitized solar cel...
