Research Abstract	In the present research proposal, the core shell structures of ZnO and TiO_2 were proposed to fabricate high efficient dye sensitized solar cells (DSSC). In order to achieve the high efficiency, the core shell structures of ZnO nanorods(NR) with dip coated TiO_2 particles, ZnO NR with screen printed TiO_2 particles and the mixture of ZnO small NR and TiO_2 particles have been fabricated and studied for DSSC performance. The ZnO NR was directly synthesized on conducting FTO glass by a wet chemical method. The core shell structure was formed by dip coating a TiO_2 sol on ZnO NR. Moreover, the TiO_2 shell layer was deposited on ZnO by screen printing of the TiO_2 particles paste. Finally, the mixture of ZnO small NR and TiO_2 nanoparticles were deposited on FTO substrate by screen printing. The DSSC cell was fabricated and studied for the performance.
