Automated Mapping System SenSol

Entire surface analysis

The SenSol mapping system is designed to measure at every location on the panel, especially at the edges.

TCO mapping

TCOs can be investigated for homogeneity in thickness, sheet resistance, spectrally resolved haze H Haze in transmission at 600 nm(λ), reflection R(λ), and transmission T(λ).

Process optimization

Running-in times for new deposition processes or after cleaning the deposition systems are significantly reduced.

The at-line SenSol mapping system is designed for quality control of thin film properties Film properties: Film thickness Refractive and absorption index Haze Sheet resistance, conductivity Transmission, absorption Crystallinity Band gap in PV manufacturing of thin films on glass sheets. A large varity of sensors Sensors: Transmission sensor
for VIS or VIS / NIR Reflection sensor
for VIS or VIS / NIR Haze sensor 4-point probe sensor Camera Ellipsometer Raman can be integrated into the SenSol sensor platform. That allows for particularized process monitoring giving the opportunity to compensate process drifts.

Oerlikon Solar, Switzerland, a leading provider of thin film PV manufacturing equipment and one of SENTECH key reference customers, ensures excellent production results by process monitoring with SenSol.

SENTECH easy-to-use, recipe oriented SenSol mapping software offers a flexible and customized interface to the manufacturer host computer as well as customer specific graphical representation of the actual measurement result.
