Fabrication and characterization of dye-sensitized solar cells based on natural plants
In this paper, the dye-sensitized solar cells (DSSCs) were fabricated based on natural dyes extracting from carrot, mulberry, purple cabbage, potato, and grapes. The ultraviolet-visible spectra suggested purple cabbage and mulberry possess better absorption at 300-550 nm. The solar cells using purple cabbage as dye achieved a conversion efficiency of 0.162% with short-circuit photocurrent density (J(sc)) of 0.621 mA/cm(2), open circuit voltage (V-oc) of 0.541 V and fill factor (FF) of 0.484. The Infrared spectra revealed the bond of O-H, C-C, C-O, C-H were existed in purple cabbage. Finally, the optimal extraction time of dyes is also presented. (C) 2018 Elsevier B.V.
