SUMMARY

The discussion centers on obtaining thin films of P3HT:PCBM for Differential Scanning Calorimetry (DSC) analyses, specifically for solar cell applications. The user initially attempted drop casting but found it inadequate for achieving the desired structure. A recommended method is to spin coat the P3HT:PCBM mixture onto silicon (Si) or silicon oxide (SiOx) wafers, allowing for effective DSC analysis on wafer chips. This approach ensures compatibility with the small sample sizes required for DSC containers.

PREREQUISITES
  • Understanding of P3HT:PCBM polymer blends
  • Familiarity with Differential Scanning Calorimetry (DSC) techniques
  • Knowledge of spin coating processes
  • Experience with silicon and silicon oxide substrates
NEXT STEPS
  • Research spin coating techniques for polymer films
  • Learn about the properties of P3HT:PCBM blends in solar cells
  • Explore the principles of Differential Scanning Calorimetry (DSC)
  • Investigate substrate interactions with polymer films during thermal analysis
USEFUL FOR

Researchers and practitioners in materials science, specifically those involved in solar cell development and thermal analysis of polymer films.

Hi

I want to do DSC analyses of P3HT PCBM film (active layer of the solar cell), but I'm not sure how to obtain that thin layer separately from the substrate. You know that the containers for DSC are very small.
I tried with drop casting but I think it's not the best way because I don't have the same structure as for the solar cell.

Could anyone help me?

Thanks

you could just include the substrate. Is it a solid substrate? it probably won't react near the same temperatures as the polymers.
Or you could spin coat p3htpcbm on si or siox wafers and run DSC on wafer chips.
