In this study, ZnO-TiO2 heterojunction photoanodes consisting of nanoparticles, nanorods, and hierarchical branched nanorods for dye sensitized solar cell (DSSCs) were synthesized using one step hydrothermal method technique on indium tin oxide (ITO) substrate at different temperatures (100, 150 and 180 oC) in a solution containing ZnCl2, TiCl4, ethanol and HCl. For ZnO-TiO2 heterojunction photoanodes, X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and UV–Vis absorption spectroscopy were utilized to characterize the thin films. The photoelectrochemical performance results show that the DSSCs composed of ZnO-TiO2 thin films have the power conversion efficiency on nanoparticles (1.21%), nanorods (2.91%), and hierarchical branched nanorods (6.61%), respectively. Because of the high power conversion efficiency, hierarchical branched nanorods can be taken account of as a considerable development in the solar cell performance for QDSCCs.

Öz

Bu çalışmada, boya ile duyarlılaştırılmış güneş pili (BDGP) için nanopartiküller (NP), nanoçubuklar (NÇ) ve hiyerarşik dallı nanoçubuklardan (HDNÇ) oluşan ZnO-TiO2 hetero yapı fotoanotları, indiyum kalay oksit (ITO) substratı üzerinde ZnCl2, TiCl4, etanol ve HCl içeren bir çözelti ortamında farklı sıcaklıklarda (100, 150 ve 170 ° C) bir adım hidrotermal yöntem tekniği kullanılarak sentezlendi. ZnO-TiO2 hetero yapı fotoanot ince filmleri karakterize etmek için X-ışını Kırınımı (XRD), Taramalı Elektron Mikroskobu (SEM), Enerji Dağılımlı Spektroskopi (EDS) ve UV-Vis Spektroskopisi kullanıldı. Fotoelektrokimyasal performans sonuçlarından, ZnO-TiO2 ince filmlerden oluşan BDGP’lerinin nanopartiküller (% 1,21), nanoçubuklar (% 2,91), ve hiyerarşik dallı nanoçubuklar (% 6,61) üzerinde güç dönüşüm verimine sahip olduğu görülmektedir. Yüksek güç dönüşüm verimi nedeniyle hiyerarşik dallı nanoçubuklar, BDGP'ler için güneş pili performansında önemli bir gelişme olarak dikkate alınabilir.
