A new series of transparent gel polymer electrolytes are prepared by adding various weight percent of thiourea coupled with poly(ethylene oxide) for the application of dye-sensitized solar cells. Coupling of thiourea in the presence of iodine undergoes dimerization reaction to produce formamidine disulfide. Fourier Transform Infrared spectroscopy shows that the interactions of thiourea and formamidine...
Dye-sensitized solar cells were fabricated using viologen impregnated PVDF with TiO 2 nanofiller as a solid polymer electrolyte sandwiched in between N3 (cis-di(thiocyanato)N,N′-bis(2,2′-bipyridyl-4,4′-dicarboxylic acid)-ruthenium(II)) dye adsorbed over TiO 2 nanocrystalline film as anode and conducting carbon cement coated over conducting glass as cathode to mainly impede the back-electron...
