Abstract

This study was aims to get unique morphological structure of CNT/TiO2doped ZnO nanocomposite using sol-gel method for better DSSC efficiency. The ZnO solution was prepared as follows; zinc acetate was dissolved in ethanol and stirred for 15 min at 60 °C. The CNT/TiO2solution start with a combination of 2-propanol (50 ml) anhydrate, TTIP and 0.5 gram of CNT were initially prepared. The 2 solution were combined and stirred vigorously. All samples are designated as CNT/TiO2 - x, where x is the mol % of the Zn [x = (a) 0.1, (b) 1.5 and (c) 2.5]. The SEM analysis images composed of porous TiO2and nanoflake ZnO nanocomposite, and the thickness of the CNT/TiO2doped ZnO paste sample is around 19.73μm. The XRD analysis showed two different main peaks for TiO2(110) and ZnO (101) were formed as anatase/hexagonal structure. The crystalline size of anatase TiO2nanoparticle was 18.04 nm, and hexagonal ZnO were 40.99 nm and 73.78 nm in diameter. The percentages efficiency (η) for 0.5%, 1.5 %and 2.5mol %were as follows 2.2 %, 2.4 % and 2.8 %, respectively.
