UK scientists observe LID in action
A team of researchers from Manchester University claims to have identified the dominant process causing light-induced degradation in silicon solar cells. The process, termed “trap-assisted auger recombination”, arises from a defect in the bulk of the silicon material which lies dormant until exposed to sunlight.
Let’s mitigate LID & LeTID!
Cell degradation: LID in p-type monocrystalline PERC cells has caused serious issues in PV plant performance. Now, it can be prevented with regeneration processes or by replacing boron with gallium. The cause of LeTID in multicrystalline PERC cells, meanwhile, is still a mystery, but researchers have proposed an industrial solution to address it.
