Abstract

Dye sensitized solar cell (DSCC) is one of the most promising devices for the solar energy conversion due to their low production cost and environmental friendliness. Being rich in biodiversity, Nepal has good potential to extract natural dyes for the research of dye sensitized solar cells. The extract of pomegranate (Bedana) Punica granatum L.; Indian Black Berry (Jamun) Syzigium cumunii and Seabuckthorn Hippophae sp were used as a natural sensitizer of a wide band gap semiconductor ZnO based in DSSC. ZnO nanorods layer were fabricated using sol-gel spin coating technique. This paper reports the fabrication and study of I-V characteristics of ZnO based DSSCs with natural dyes using equivalent circuit one-diode model. The equivalent circuit parameters of DSSCs with natural dyes were studied. The electric energy conversion efficiency was found to be 1.41%, 1.19% and 0.97% for Bedana, Jamun and Seabuckthorn dyes, respectively.
