In this report, the cell performance of quasi solid dye-sensitized solar cells based on the low molecular weightPoly(ethylene glycol) (PEG400), 1-methyl-3-propylimidazolium iodide (MPII), iodine (I2) with and without the addition of hybrid inorganic-organic nanoparticle (TiO2-POEM, SiO2-POEM) is investigated. The effect of hybrid inorganic-organic nanoparticles (TiO2-POEM, SiO2-POEM) in electrolytes, were studied on the coordination interactions (FT-IR), structure change (WAXS), galation phenomenon (DSC, Photo), morphology and network change (EF-TEM), penetration to TiO2 photoelectrode (FE-SEM), ionic conductivity and cell photovoltanic performance of quasi solid electrolytes (TiO2-POEM/PEG400,SiO2-POEM/PEG400). The quasi solid dye-sensitized solar cells with PEG400 electrolyte including 10wt% hybrid inorganic-organic nanoparticles (TiO2-POEM, SiO2-POEM) showed the best photovoltaic performance. (short circuit current (Jsc) of 9.142, 8.813 mA/cm2, open circuit voltage (Voc) of 0.628, 0.679V, fill factor (FF) of 0.572, 0.481 and the overall solar energy conversion efficiency (η) of 3.29, 2.88% under illumination of 100mW/cm2, respectively) |
