Photovoltaic Performance of Rainbow Dye-Sensitized Solar Cells using Gardenia Yellow, Blue and Red |
| 초록 |
The photovoltaic performance of rainbow dye-sensitized solar cells using yellow, blue and red extracted from gardenia was investigated to harvest light over a wide range of wavelengths. The adsorption characteristics, photovoltaic efficiencies, and electrochemical properties of the rainbow DSSCs were investigated. Adsorption kinetic data for the dyes were obtained in a small adsorption chamber. The adsorption capacities of gardenia yellow, blue, and red were 1532 mg/g, 262 mg/g, and 192 mg/g, respectively. The adsorption kinetic values determined from a pseudo-second-order model were in the range of 8.01 × 10−5 to 3.32 × 10−3 g/(mg min). The photovoltaic performance of a photo-electrode with an adsorbed mixture of the three dyes was evaluated from current–voltage measurements. It was found that the conversion efficiency of the rainbow DSSC was highly dependent on the adsorption properties of the cocktail dyes on TiO2 films. |
