Adhesion testing for photovoltaic laminates

An adhesion test allowing for the realistic assessment of adhesion needs for PV modules has been developed. The difference is that the test is conducted in-situ during ageing experiments. Weights were attached to the backsheet of tested PV mini-modules in order to test stability of lamination and adhesion. All samples were tested at standard test conditions of module temperature of 85ºC and 85% relative humidity. It is shown that appropriately laminated samples were able to withstand the force of 20g/cm for 1000 hours.
