Characterization methods for dye-sensitized solar cells (DSC)

Toolbox: A series of methods to characterize dye-sensitized solar cells (DSC)

  1. How are electrons transported through the porous TiO2 film? 
  2. What factors affect charge transport and recombination?
  3. How can we optimize the DSC?

These are just a few questions that we try to answer in our research. We use a series of characterization techniques, the "Toolbox", that we use on complete DSCs under typical solar cell operating conditions.

The toolbox gives information on:

  • Electron transport
  • Electron lifelime
  • Electron concentration
  • Fermi level (electrochemical potential) in TiO2

In addition, we use Photoinduced Absorption spectroscopy to see the spectrum of electrons and intermediates in DSCs.
