The third generation of solar cells that found by Gratzel in 1991 was called Dye Sensitized Solar Cell (DSSC). DSSC is composed of five parts namely Indium Tin Oxide (ITO) as a substrate; TiO 2 and SnO 2 nanoparticles as semiconductor materials; natural dyes (chlorophyll alfalfa) as an electron donor; gel electrolyte as electron transfer; active carbon as a catalyst which can convert light energy into electrical energy. The layer of two semiconductors was deposited on top of an substrat by doctor-blade method. Characterization of DSSC photoanoda materials that will be carried out in this research are: electrical characterization using Keithley IV meter, optical characteristic characterization and bandgap analysis using UV-Vis Spectrophotometer, DSSC efficiency using TiO 2 as a semiconductor highest than DSSC using SnO 2 as a semiconductor. Characterization of photoanoda layer with X-Ray Diffraction (XRD …
