letid

August 10, 2020
Understanding of LeTID remains incomplete, although its effects on PV power plant performance are recognised as being potentially significant. Friederike Kersten, Matthias Pander, Max Koentopp, Marko Turek, Werner Bergholz and Thomas Pernau of the LeTID Norm consortium outline progress towards developing a standardised test for the defect, a key step inw minimising its impact

TÜV Rheinland has awarded the first small group of PV module manufacturers with certification against LeTID (Light and elevated Temperature Induced Degradation), also known as Carrier Induced Degradation (CID).
January 30, 2019
Leading ‘Silicon Module Super League’ (SMSL) member JinkoSolar has highlighted success using new LeTID (Light elevated Temperature Induced Degradation) testing standards in minimising performance losses in its P-type mono-PERC and N-type monocrystalline solar cells.

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.

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).
October 24, 2018
PV Tech caught up with Daniel Chang, technical director at major China-based PV manufacturer JinkoSolar, to discuss the performance of installed PERC products, new testing regimes, what consumers are asking for and how to release new modules to market.
October 19, 2018
‘Silicon Module Super League’ (SMSL) leader JinkoSolar said it had supplied 10MW of its P-type mono PERC ‘Eagle’ modules (JKM295M-60) series for a PV power plant project built by Huaneng Renewables in Inner Mongolia, China.
