Tom Kenning reports on the testing of next-generation modules and efforts to ensure their longevity in the field. PV modules are generally performing well across the solar industry but recent results from leading test labs suggest that some forms of next-generation modules are showing surprising levels of degradation in just a few years.
The PVLab researchers quantify that behavior using a measure called lifetime—the average time an electron remains in an excited state before it recombines with a hole. Lifetime critically affects the energy conversion efficiency of a solar cell, and it is “exquisitely sensitive to the presence of defects,” says Buonassisi.

When solar radiation shines onto the material, electrons can absorb enough energy to jump from the valance band to the conduction band, leaving behind vacancies called holes. If all is well, before the electrons lose that extra energy and drop back to the valence band, they travel through an external circuit as electric current.
Professor Hoex emphasized that sodium is present in almost every component of PV solar panels, including glass and encapsulants. Sodium-related degradation can lead to severe issues, particularly with series resistance and contact corrosion.
