Dye sensitized solar cell (DSSC) is a well-known photovoltaic device that is used for low power application. One of the main components for DSSC is semiconductor material photoanode which will provide the pathway for electron transportation and thus determine the energy conversion efficiency of the DSSC. The most commonly used material for the semiconductor photoanode is titanium dioxide (TiO2).TiO2is a semiconductor material with wide bandgap material that is existed in three crystalline phase; rutile, anatase and brookite. This paper emphasizes the best annealing temperature for commercialized TiO2, 98% anatase powder where the temperature varies from 300 oC – 600 oC. Through this research, the best annealing temperature for anatase TiO2photoanode is at 420 °C (0.094%) with the crystallite size of 18.76 nm and particle size of 19 nm that is favorable for the dye attached and thus enhances the energy conversion efficiency of the DSSC.

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.
