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.

本研究提出了利用ZnO和TiO_2的核壳结构制备高效染料敏化太阳能电池的设想。为了提高染料敏化太阳能电池（DSSC）的效率，制备了ZnO纳米棒（NR）与TiO_2浸渍包覆颗粒、ZnO NR与TiO_2丝网印刷颗粒以及ZnO小NR与TiO_2颗粒混合的核壳结构，并对其DSSC性能进行了研究。采用湿化学法在FTO导电玻璃上直接合成了ZnO NR。采用浸渍法将TiO_2溶胶涂覆在ZnO NR上，形成核壳结构。采用丝网印刷法在ZnO上沉积了TiO_2壳层。最后，采用丝网印刷法将ZnO/NR/TiO_2纳米粒子混合沉积在FTO基底上。制作了DSSC电池并对其性能进行了研究。
