Polymethylmethacrylate (PMMA) based quasi-solid electrolyte with binary iodide salt for efficiency enhancement in TiO2 based dye sensitized solar cells
Artikel i vetenskaplig tidskrift, 2014

Enhancement of efficiency by using iodide mixture (Pr4NI and I(1), instead of a single iodide salt, in N719 dye-sensitized solar cells with a polymethylmethacrylate (PMMA) based gel electrolyte is investigated. The salt ratio is varied to optimize efficiency. With 100 wt.% KI and 100 wt.% (Pr4NI) efficiencies under AM 1.5 illumination are 3.39% and 3.21%, while 22.2:77.8 wt.% ratio KI:Pr4NI shows the highest efficiency of 3.99%. This is an efficiency enhancement of 18%. Variation of efficiency with salt composition appears to correspond to the change in short circuit photocurrent density (J(sc)) and the iodide ion conductivity.
