Fraunhofer Center for Silicon Photovoltaics CSPGas Permeation Measuring Stand
At the gas permeation stand, thin films (foils, gels) can be examined for their barrier properties and permeation parameters.
In gas permeation, the transmission rates of thin films can be determined.
- Characterization of barrier properties and permeation parameters of thin films (foils and gels)
- Determination of transmission rates: WVTR (water vapor) following ASTM F-1249, HeTR (helium), OTR (oxygen from air), also of other gases (e.g. H2S).
- Different temperatures and gas humidities are achievable
- Determination of transmission rates: WVTR (water vapor) following ASTM F-1249 and DIN EN ISO 15106-3
