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 model. Devices were Assembled using ZnO nanoparticles and natural sensitizers. DSSCs based on ZnO nanoparticles and ethanol extract of Amarathus iresine sensitizers have shown relatively better conversion efficiency of 0.039. Incident photon to current conversion efficiency (IPCE), short circuit current density (Jsc) and open circuit voltage (Voc) were measured for all the sensitizers.
