Abstract

Abstract Zinc oxide having the chemical formula ZnO, while titanium dioxide is titanium oxide having the chemical formula TiO2. Zinc oxide and titanium dioxide are inorganic compounds. Zno and TiO2 are often used for Dye-Sensitized Solar Cell (DSSC). This research was conducted by mixing ZnO and TiO2 as photoanodes. The mixture of ZnO and TiO2 is made by mixing ZnO and TiO2 with a ratio of 1:1, 1:2, 1:3 then dissolved in ethanol. The natural dye used is broccoli extract (Brassia oleracea var. italica). Fabrication is carried out using FTO glass with a work area of 1cm × 1cm. The efficiency results obtained by nanocomposite ZnO/TiO2 (1:1) with an efficiency (η) of 0.07180%, nanocomosite ZnO/TiO2 (1:2) with an efficiency (η) of 0,1555% nanocomosite ZnO/TiO2 (1:3) with an efficiency (η) of 0.1713%. When compared to the efficiency using ZnO/TiO2 (1:1) with TiO2, the efficiency increased by 0.002%. At ZnO/TiO2 (1:2) the efficiency increased by 0.0886%. Whereas at ZnO/TiO2 (1:3) the efficiency increased by 0.1023%.
