Polymer-Doped Molten Salt Mixtures as a New Concept for Electrolyte Systems in Dye-Sensitized Solar Cells

Abstract

A conceptually new polymer electrolyte for dye-sensitized solar cells is reported and investigated. The benefits of using this type of electrolyte based on ionic liquid mixtures (ILMs) and room temperature ionic liquids are highlighted. Impedance spectroscopy and transient electron measurements have been used to elucidate the background of the photovoltaic performance. Even though larger recombination losses were noted, the high ion mobility and conductivity induced in the ILMs by the added polymer result in enhanced overall conversion efficiencies.

Electrospun Poly (Ionic Liquid) Membrane Based Solar Cell For Sustainable Clean Energy

“…These traditional fossil based fuel usages caused environmental problems such as carbon dioxide emission and irreversible climate changes (Luis et al, 2019). Among the energy sources existing, solar energy can fulfill the world's ever growing energy needs (Muthuraaman et al, 2017). Photovoltaic cells directly convert solar energy to electricity.…”

Improved performance of dye-sensitized solar cells upon sintering of a PEDOT cathode at various temperatures

“…Adding additives to the electrolyte (like 1,2-dimethyl-3propylimidazolium iodide or 4-tert-butylpyridine guanidinium thiocyanate) has hindered the dark current and increased the efficiency to a degree, but corrosion of the noble metal cathode (like Pt, Au) has signicantly restricted its development and led to the reevaluation of other redox couples, such as Co(II/III) polypyridyl complex, ferrocenium/ferrocene (Fc/Fc + ) couple, Cu(I/II) complex, and thiolate/disulde mediator. [11][12][13][14][15][16][17][18] In the cathode system, the cobalt electrolyte and some other electrolytes have shown less efficiency with the normally used platinum (Pt) electrode compared to other cathodes. In DSSCs, the cathode performs an important role in regenerating the redox couples by collecting the electron from the external circuit.…”
