본문내용
* Dye is varied depending on the
type of substituent X
* 3 conditions are needed
- absorb all visible light.
- bond with nano-oxided substance.
- resist against heat and optics.
* Dye have a major impact in the
efficient of DSSCs
1.Illumination of Sunlight
- Absorbed by Dye sensitized.
2. Excited Dye molecule injects
electron to TiO2.
3. Electron moves to external
load and transmits electric
energy.
4. Dye becomes to ground
state by redox in I3- -> 3I-
reaction.
