Improvement of the dye loading that could be correlated with an increase in the surface area of the layer and enhanced Jsc performance in dye-sentisized solar cell’s. Also shifts the conduction band edge of TiO2 photoelectrode toward a negative potential value enhanced Voc performance in dye-sentisized solar cell’s. Beside, to better penetration of electrolyte, it is essential to use the mesoporous or macroporous TiO2 photoelectrode structure than microporous TiO2 photoelectrode structure. For this reason, TiO2 nanoparticles size, morphology and structure in dye-sentisized solar cell’s photoelectrode are a very important factor for the solar energy conversion efficiency.That’s why enhanced photovoltaic performance of dye-sentisized solar cell’s were achived by modifying the TiO2 for photoelectrode with ATRP process with polymer POEM andsol-gel process with TTIP. Finally, DSSCs with various size Janus novel morphology TiO2 (TiO2-POEM/TTIP) in photoelectrode showed the best photovoltaic performance with inorganic/organic electrolyte (Jsc) of 7.27mA/cm2, (Voc) of 0.771V, (FF) of 0.59 and the (η) of 3.33% under illumination of 100mW/cm2, respectively) |
