Abstract

Dye Sensitized Solar Cell (DSSC) is the third generation of solar cells. DSSC is formed by sandwich structure, there are five parts: ITO glass (Indium Tin Oxide) as substrate; TiO2 as semiconductor material; dye (chlorophyll-turmeric-mangosteen) as an electron donor; gel electrolyte as electron transfer and active carbon as a catalyst in the counter electrode. The synthesis of nanometer-sized TiO2 powder is obtained by coprecipitation method. From the research that has been done, the efficiency of DSSC with 10 µm TiO2 layer thickness bigger than 20 µm and 30 µm layer thickness. The DSSC efficiency result is 0.25% for 10 µm TiO2 layer thickness , 0.143% for 20 µm TiO2 layer thickness, and 0.195% for 30 µm TiO2 layer thickness.
