Abstract: Natural pigments extracts from Bougainvillea spectabilis, Carissa Ovata, Hibiscus sabdariffa, Amarathus iresine herbisti, Beta vulgaris, are used as natural sensitizers for a dye sensitized solar cell (DSSC). ZnO nanoparticles were synthesized using sol-gel method and the size of the nanoparticle was determined using effective mass approximation mo... Show More

Abstract: Dye-sensitized solar cells (DSSCs) were fabricated using natural dyes extracted from roselle flowers and carica papaya leaves extract as photosensitizers. The photovoltaic perfomance of the DSSCs were evaluated under 100 mAcm^-2 light intensity. The roselle (Hibiscus Sabdariffa) extract sensitized solar cell gave a short circuit current density (Jsc...
