Dye Sensitized Solar Cell (DSSC) has been made from ZnO-TiO2, activated carbon, electrolyte, ITO coatingHCl and Na2SO4. The process of making ZnO-TiO2 used the method sol gel. The results of the ZnO-TiOlayer2 with various dehydrolysis temperatures: 3000C, 5500C, 8000C, 10000C and 12500C, were characterized using X-Ray to determine the crystal size and peak wavelength. The results of X-Ray analysis on the ZnO-TiO layer have grain sizes ranging from (457.425; 45.74), (427.717; 42.77) and (374.419; 37.44) nm. The X-Ray The highest and lowest peaks were found at 800oC. The size of the Scanning Electron Microscopy (SEM) type EVO MA 10 was to determine the surface morphology. The results of SEM analysis on the ZnO-TiOlayer2 have grain sizes ranging from (35.325±4.701); (47.451 ± 13.242) and (51.541 ± 13.564) μm for each dihidrolisis temperature of 300 ° C, 550 ° C, 800 ° C, 1000oC and 1250oC. To determine the absorbance of the dye to a layer of ZnO-TiO2 used UV - VisSpectrophotometer RayLEIGH – UV-1601 and I-V brandmeter Keithley for DSSC current and voltage measurement. The UV-Vis Spectrophotometer results showed that the ZnO-TiOlayer2 successfully absorbed the solution dye in the visible light absorption area. The temperature change of the hydrolysis suggests that heating the ZnO-TiOlayer2 influences solar cell performance. The maximal efficiency at 800C is (7..1±0.025)x10-3 % using IV-a meter Keithley and (8.5±0.35)x10-3 % using a circuit. The result can provide a current of 1.9-4.5 mA and a maximum voltage of 3.7 - 8.5 eV.
