Fabrication and Characterization of Dye-Sensitized Solar Cell using Chemically Grown ZnS Nanoparticles

In this work, we have fabricated dye-sensitized solar cell (DSSC) based on chemically grown ZnS nanoparticles with three different source of dye namely Gerbera jamesonii, Rosa indica and Acalypha wilkesiana leaves extract. Anthocyanin, a kind of natural dye found in the leaves of plants and flowers was used as photosensitizers in preparing dye-sensitized solar cell. The optical properties of anthocyanin present in three dyes were also studied. Morphological properties have been studied by atomic force microscopy on ZnS film as well as on ZnS film with dye. The current-voltage characteristics of the dye-sensitized solar cell had been studied in light condition. The DSSC is characterized by the measurement of open circuit voltage, short circuit current density; efficiency and fill factor. The efficiency of three dye solar cell is different and it is maximum for Acalypha wilkesiana leaves extract dye.
