The influence of 5-amino-1,3,4-thiadiazole-2-thiol (ATDT) on the ionic conductivity of poly(vinylidinefluoride-co-hexafluoropropylene) (PVDF-HFP) polymer electrolytes with mixed iodide salts (potassium iodide (KI) and tetrabutylammonium iodide (TBAI)) and iodine (I2) were studied for dye-sensitized solar cells (DSSCs). The pure and different weight percentage (wt%) ratios (2%, 3%, 4%, 5% and 6%) of...
Gel polymer electrolytes (GPEs) consisting of polyvinyl alcohol (PVA) and double iodide salts have been prepared using ethylene carbonate (EC) and propylene carbonate (PC). Potassium iodide (KI) and tetramethylammonium iodide (TMAI) were used as mixed salts for making the electrolyte ion conducting. The highest room temperature (298K) conductivity of 12.91 mS·cm−1 is obtained for the GPE containing...
In this work, polyvinyl alcohol (PVA)-salt gel polymer electrolytes (GPE) have been prepared with ethylene carbonate (EC) and propylene carbonate (PC) dissolved in dimethyl sulfoxide (DMSO). Potassium iodide (KI) and tetrapropyl ammonium iodide (TPAI) salts have been used to provide the conducting ions. The single salt system (containing KI only) with composition 15.20 wt. % PVA - 31.73 wt. % KI -...
Films of solid polymer electrolyte based on chitosan and silver triflate (AgCF3SO3) have been prepared by casting technique. As a confirmation, the UV-vis results show the temperature dependence of silver nanoparticles. The dielectric constant increases with increasing salt concentration. The dielectric constant and dielectric loss curves show the higher values in the low frequency region and they...
