Scientists from Trina Solar, Longi, Fraunhofer ISE, and other entities have looked at light and elevated temperature-induced degradation (LeTID) in gallium-doped Czochralski silicon (Cz-Si:Ga) PERC cells. They have found little relevant degradation.Over time, LeTID can cause significant performance losses in PV modules in the field. The problem was first recognized around 2012; the industry did not know the exact cause behind it, but it has been quick to develop mitigation strategies. Understanding the effectiveness of these strategies, and ultimately eliminating performance losses associated ...Den vollständigen Artikel lesen ...
