Used combinations were (i) TiO 2-n (ii) TiO 2-b (iii) ZnO-n (iv) TiO 2-n: TiO 2-b in 1:1 ratio (v) ZnO-n: TiO 2-n in 1:1 ratio (vi) ZnO-n:TiO2-b in 1:1 ratio respectively along with N719 dye. Bulk and nano TiO 2 were blended individually with nano ZnO and their photo voltaic parameters were examined. The Particle size was further confirmed by XRD analysis. The morphology, porosity and grain size of the ZnO was studied by SEM analysis. ZnO nanoparticles were synthesized by sol-gel process. In this study, working electrode modification was done by using hybrid metal oxides as in the fabrication of DSSC to increase the efficiency of the device. We anticipated that combination of these two should help us to get the better devices. But on the other hand, wide band gap semiconductor such as ZnO has higher stability and electron mobility. ![]() ![]() Most of the time best choice of metal oxide semiconductor is TiO 2 because of its high electron injection rate. Dye sensitized solar cells (DSSCs) have fascinated researchers across the globe since their inception in 1991, due to their easy preparation protocols compared to the conventional silicon solar cells and eco-friendly nature.
