Investigating the link between LeTID and hydrogen induced contact resistance in PERC devices
AIP Conference Proceedings, 2022 In recent years academia and industry have made significant efforts to mitigate the problem of LeTID in silicon solar cells, particularly in p-type multi crystalline PERC cells. Many of these approaches involve a post-firing thermal anneal between 300-500 °C after metal contact firing.

Impact of Temperature and Doping on LeTID and Regeneration in mc-Si
, 2017 Light and elevated temperature induced degradation can be observed in multicrystalline Si PERC solar cells and results in efficiency losses of up to 12%rel. This work investigates the impact of temperature as well as doping on the degradation and regeneration behavior of lifetime samples.

Study of changes in PL spectrum from defects in PERC solar cells with respect to LeTID [PDF]
AIP Conference Proceedings, 2019 Illumination at elevated temperature may cause an efficiency loss of more than 10 %rel. in mc-PERC cells. In this study, we have looked for changes in the photoluminescence spectrum of mc-PERC cells before and after light and elevated temperature induced degradation and, subsequently, after a following regeneration has commenced. We found that combined

Journal of Applied Ecology, Volume 63, Issue 9, September 2026.Researchers should move from characterising factors impacting scientific evidence use to identifying and testing interventions to facilitate its use by conservation decision makers. Since these factors are interlinked, implementation and testing of actions that tackle multiple barriers should be prioritised.
