The complex chemistry of organic photovoltaic films make PHI
TOF-SIMS instruments an attractive option for compositional
characterization of these films. Using an argon gas cluster ion beam
for sputtering and a liquid metal ion gun for analysis,
characteristic mass fragments of the various materials in the complex
film structure are observed.
