Telah dilakukan penelitian tentang pembuatan pasta ZnO dengan penambahan dish detergent dan PVA pada kaca konduktif terhadap efisiensi dye sensitized solar cell (DSSC) dari ekstrak bunga rosela (Hibiscus sabdariffa L.). Penelitian ini bertujuan untuk menghasilkan lapisan ZnO nanopori dan untuk mengetahui pengaruh pembuatan pasta ZnO dengan penambahan dish detergent dan PVA terhadap efisiensi dye sensitized solar cell (DSSC). Penelitian dilakukan dengan pembuatan elektroda kerja (working electrode) dari lapis tipis ZnOyang mengadsorb antosianin bunga rosela, elektroda perlawanan (counter electrode) dari karbon dan elektrolit I-/I3- sebagai pasangan redoks. Karakterisasi DSSC meliputi serapan panjang gelombang zat pewarna bunga rosella, kristalinitas ZnO, struktur morfologi lapis ZnO dan karakteristik ikatan antara ZnO dengan senyawa antosianin. Nilai efisiensi DSSC ditentukan dengan metode kurva arus dan tegangan. Hasil penelitian dapat diperoleh lapisan ZnO berukuran nanopori sebesar 71,43 nm, dan efisiensi DSSC yang diperoleh untuk ZnO dengan dish detergent sebesar 2,964 x 10-4% sedangkan ZnO dengan PVA diperoleh efisiensi sebesar 0,712 x 10-4%.

ThePreparation of nanorod involves simple and novel design of sol-gel process. Further, by using the prepared nanorods,working electrode will be prepared and it will be sensitized with ruthenium dye. A platinum coated FTO electrode will beused as a counter electrode. Dye sensitized solar cell will be assembled by using the working electrode and counterelectrode. FE-SEM and UV characteristics have been carried out at 250ᵒC, 350ᵒC&450ᵒC. The size and band gap ofnanorod at these temperatures has been found out to be 1μm and 2.95eV, 200nm and 2.86eV, 100nm and 2.79eVrespectively. The power conversion efficiency and the fill factor have been obtained as 2.72% and 0.722 respectively.

Working Electrode

This study investigates the optimization of a ZnO-coated TiO2 working electrode and the effect of this hybrid electrode on the power conversion efficiency of a dye-sensitized solar cell (DSSC). This electrode was fabricated by dipping the TiO2 electrode with the TiCl4 treatment in a solution of zinc acetate dehydrate [Zn (CH3COO)22H2 and ethanol. The effect of the concentration of Zn (CH3COO)22H2O on the band gap of a working electrode and on the power conversion efficiency of a DSSC was also examined. As the concentration of ZnO decreased to 0.002 from 0.004 mol/L, the band gap of the working electrode decreased to 3.08 eV from 3.87 eV, and the power conversion efficiency () of the DSSC increased to 3.8573% from 3.3514%. Interestingly, the of DSSC with a ZnO-coated TiO2 hybrid electrode substantially exceeded that of the conventional DSSC due to TiO2 orbital hybridization and an energy barrier between ZnO and TiO2 that suppressed the electron recombination.

Optimum Annealing Temperature

Titanium Dioxide (TiO2) layer was deposited on conductive transparent glass substrate (ITO glass) at room temperature using doctor blade method. The TiO2layer was annealed at 450 °C, 550 °C and 650 °C in a vacuum chamber for 1 hour. The morphology and porosity of TiO2after annealed at different temperatures were characterized using Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and Spectrum Parameter Analyzer (SPA). Photocatalytic activity at different annealing temperatures was measured for dye sensitized solar cell that was fabricated using the new in-house carbon nanotubes-graphene hybrid as the dye material. The results showed that, the optimum annealing temperature was 450 °C. At that temperature, the active photocatalytic activity, which was initiated by the anatase TiO2formation in paired with hybrid system as the working electrode, has contributed to the highest conversion efficiency of 0.0016% of the device performance.
