Measurement procedures for materials used in photovoltaic modules - Part 1-4: Encapsulants - Measurement of optical transmittance and calculation of the solar-weighted photon transmittance, yellowness index, and UV cut-off frequency
EN 62788-1-4:2016

This part of IEC 62788 provides a method for measurement of the optical transmittance of
encapsulation materials used in photovoltaic (PV) modules. The standardized measurements
in this procedure quantify the expected transmittance of the encapsulation to the PV cell.
Subsequent calculation of solar-weighted transmittance allows for comparison between
different materials. The results for unweathered material may be used in an encapsulation
manufacturer’s datasheets, in manufacturer’s material or process development, in
manufacturing quality control (material acceptance), or applied in the analysis of module
performance.
This measurement method can also be used to monitor the performance of encapsulation
materials after weathering, to help assess their durability. The standardized measurements
are intended to examine an interior region within a PV module, e.g., without the effects of
oxygen diffusion around the edges of the cells. Subsequent calculation of yellowness index
allows for quantification of durability and consideration of appearance. The change in
transmittance, yellowness index, and ultraviolet (UV) cut-off wavelength may be used by
encapsulation or module manufacturers to compare the durability of different materials.
