Abstract
Here, we describe a nanocomposite polymer electrolyte prepared using a solution casting technique.
Highlights
Solid polymer electrolytes (SPEs) are prepared by complexing polymers with metal salts
In order to assess the performance of the nanocomposite polymer electrolytes (NPEs), the sample was fabricated in an fluorine-doped tin oxide (FTO)/TiO2-dye/Polyethylene oxide (PEO)–lithium iodide (LI)–0.6 wt% NCC/I2/Pt dye-sensitized solar cell (DSSC) and tested under illumination of light
Free PEO–LI standing films with various NCC weight ratios were successfully prepared via performing a solution casting technique
Summary
Solid polymer electrolytes (SPEs) are prepared by complexing polymers with metal salts. The diffusion of electrons in the conduction band of TiO2 is considered to occur via an ambipolar diffusion mechanism.[29–31] In these studies, the lithium cation (Li+) was used due to the above considerations and due to its small cationic radius allowing it to penetrate into the dye-coated TiO2 film and form ambipolar Li+–eÀ pairs with the electrons in the conduction band of TiO2. The lithium cation (Li+) was used due to the above considerations and due to its small cationic radius allowing it to penetrate into the dye-coated TiO2 film and form ambipolar Li+–eÀ pairs with the electrons in the conduction band of TiO2 This feature has been indicated to increase the transport speed of electrons in the TiO2 network and enhance current density ( JSC) levels of the DSSCs.[32,33]. The potential practicality of the polymer electrolyte in DSSCs was investigated
