Example of PV Analysis (3)
Chemical Analysis and Physical Properties Evaluation of Sealant



ANAC can prepare samples of a sealant of PV module at various positions and can analyze and evaluate those samples to get various kinds of chemical and physical data.

The main Evaluation items of a Sealant

Evaluation Items Analytical Methods
Cross-linked state Solid viscoelasticity, Pulse NMR
Electric resistance Volume resistivity (high‐humidity/temperature)
Light transmittance Ultraviolet / Visible Spectroscopy
Quantity of free acetic acid Ion Chromatography (IC)
Quantity of additives FT-IR, GC, GC/MS, LC/MS, ICP etc.
Quantity of water Karl Fischer method
Specific heat capacity DSC

※Sampling of sealants from a PV module is available as well as measurements.

Example : Viscoelasticity and Volume Resistivity

No difference in Elastic Modulus and Volume Resistivity between samples at a normal position and a whited position was observed.
