Characteristics and Synthesis of ZnO/TiO2 Semiconductor Using Sol- Gel, Spin Coating as Solar Cell Material

The purpose of this research was to characterize and synthesize ZnO-TiO2 using activated carbon, an electrolyte, a Micro Slides layer, and HCl as a precursor. Utilizing Sol-Gel or Spin Coating and grinding it with a stirrer, the characteristics and synthesis procedure was carried out. First, Scanning Electron Microscopy (SEM) type 250 Quanta, the surface morphology and XRD of ZnO-TiO2 samples with varying dehydrolysis temperatures (4000C, 5000C, and 6000C) were determined. The spectrum of the findings of SEM examination on ZnO, TiO2, and ZnO-TiO2 calcined at temperatures of ZnO 400o C, TiO2 500o C, and ZnO–TiO2 600o C ranges from (116.52), (114.84), and (600). (112.58). According to XRD examination, the crystal diameters for each dehydrolysis temperature of 400 °C, 500 °C, and 600 °C were 79.21 nm, 49.21 nm, and 45.34 nm, respectively. The fluctuation of the dehydrolysis temperature demonstrates that heating of the ZnO-TiO2 influences the performance of the solar cell, where the highest efficiency value is (5.10.045) x10-3% when measured with the IV-meter Keithley and (7.50.25) x10-3% when measured with a circuit at 600 C. This item can emit a maximum current of 2.5–3.5 mA and voltage of 3.3–8.5 eV.
