Hanwha Q CELLS’ touts success of its anti-LeTID module performance in Fraunhofer CSP tests

Recently billed by solar industry experts as another degradation crisis that could be worse than the impact on PV module performance than PID (potential Induced Degradation), ‘Silicon Module Super League’ (SMSL) member, Hanwha Q CELLS has highlighted that both its mono and multicrystalline products have performed exceptionally well in LeTID (Light and elevated Temperature Induced Degradation) tests undertaken by Fraunhofer CSP.

Is LeTID degradation in PERC cells another degradation crisis even worse than PID?

When we visit conferences and industrial players, we are very often surprised at how many responsible scientists for PERC production have never heard about the severe degradation effects that PERC devices can show – in particular when talking about LeTID (Light and elevated Temperature Induced Degradation) alias Carrier Induced Degradation (CID).
