Enhanced Light Harvesting Efficiency by Först Resonance Energy Transfer using Organic Blue Dye in Quasi-solid State DSSC |
| 초록 |
The mechanism of DSSC is based on the injection of electrons from the photo excited dyes into the conduction band of the semiconductor electrode. Thus, the light harvesting effect of dye plays an important role in capturing the photons and generating the electron/hole pair, as well as transferring them to the interface of the semiconductor and the electrolyte, respectively. We have demonstrated Först resonance energy transfer (FRET) in the quasi-solid type dye-sensitized solar cells between organic fluorescence materials as an energy donor doped in fluorine polymer gel electrolyte and organic dye as an energy acceptor in quasi-solid electrolyte. The strong spectral overlap of emission /absorption of energy donor and acceptor is required to get high FRET efficiency. The judicious choice of energy donor allows the enhancement of light harvesting characters of energy acceptor in quasi-solid dye sensitized solar cells which increase the power conversion efficiency. |
