The increased of photovoltaic dye-sensitized solar cell (DSSC) efficiency using nanocomposite ZnO/TiO2 with natural dye leaves of grass jelly (Cyclea barbata)

Zinc Oxide (ZnO) is a semiconductor material that is used in addition to Titanium Dioxide (TiO2) used in the manufacture of Dye-Sensitized Solar Cell (DSSC). ZnO synthesized by using sol-gel mixture of zinc nitrate tetrahydrate (Zn (NO3)2.4H2O), ammonium hydroxide (NH4OH) and polyethylene glycol (PEG). In this study, the dye was extracted from the leaves of grass jelly (Cyclea barbata). Nanocomposite ZnO/TiO2 (mixture between ZnO and TiO2) was obtained by adding the results of the synthesis of ZnO and TiO2. From fabrication deposited one layer on the FTO glass with a spacious work area 1cm × 1cm obtained increase in conversion efficiency (η) on nanocomposite ZnO/TiO2 compared with ZnO and TiO2, with efficiency (η) TiO2 0.0130%, ZnO 0.0011% and nanocomposite ZnO/TiO2 0.0696%.
