i am working on aqueous base DSSC and facing the dye desorption issue from the photoanode when interact with water, i want to know some techniques to reduced dye desorption.
Thanks
Dear Muhammad Sadiq , you may want to refer to the following: https://purehost.bath.ac.uk/ws/portalfiles/portal/187920954/Thomas_Risbridger_PhD_Thesis.pdf
Hope it helps.
Dear MS
1. Increase the surface area of the TiO2 particles.
2. Increase the hydrophobicity of the TiO2 surface.
3. Increase the thickness of the TiO2 layer.
4. Use a hydrophobic binder to bind the TiO2 particles together.
5. Use a hydrophilic binder to bind the TiO2 particles together.
6. Increase the pH of the electrolyte solution.
7. Use a surfactant to reduce the surface tension of the electrolyte solution.
8. Use a dye with a higher affinity for the TiO2 surface.
9. Use a dye with a lower solubility in the electrolyte solution.
10. Use a dye with a higher molecular weight.
Hi!
Dye desorption is a common issue in DSSCs that can lead to a decrease in the overall performance of the device. There are a few different techniques that can be used to reduce dye desorption in aqueous-based DSSCs:
It's worth noting that in order to effectively reduce dye desorption it may be necessary to use a combination of these techniques. Additionally, it's important to keep in mind that each DSSC system is unique and the most effective technique(s) will depend on the specific system being studied.
