THE EFFECT OF ZnO-TiO2 SYNTHESIS ANALYSIS USING SOL-GEL METHOD ON CALCINATION TEMPERATURE OF THIN FILM AS AN ALTERNATIVE ENERGY MATERIALS

The manufacture of solar cells from ZnO – TiO2 is synthesized at 400°C, 500°C, and 600°C. This research was carried out by synthesizing ZnO, TiO2, and ZnO + TiO2 with the sol-gel method and was ground using a stirrer at 80°C, 200 rpm for 30 minutes. In this study, the thin-film glass used was Select Micro Slides, which measures 76 x 26 mm of 1.0/1.2 mm thick. The synthetic mixture used is 98% ethanol. Before testing, materials synthesis resulted from 2x2 mm coated thin glass was furnished for 1 hour with the calcination temperature of 400°C, 500°C, and 600°C. The results or the characterization performed on ZnO with a temperature of 400°C, has a peak point: 50 - 20. The graph described that there are two pairs of the same peak point, namely: 27 and 20. TiO2 with a temperature of 500oC has a peak point of 300 - 20, and 20. And ZnO + TiO2 with a temperature of 600°C has a peak point of 340 - 4. The temperature of crystal size varied; ZnO at a temperature of 400°C has a crystal size of 792.0585 AO or 79.205 nm, TiO2 at a temperature of 500oC has a crystal size 492.10489 AO or 49.21 nm, and ZnO + TiO2 at a temperature of 600°C has a crystallite size of 453 440 Ao or 45.34 nm. The result of the synthesis was different from the XRD characterization, wavelength, and crystal size. ZnO and TiO2 can influence various characteristics such as; increasing peak point, wavelength, crystal size, and other effects that can provide heat or electrical energy.
