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.

Though growth is on the way for n-type technology – it is expected to account for a 12% market share in 2021, p-type wafers, whether mono or multicrystalline, will continue to represent an 88% market share, according to the International Technology Roadmap for Photovoltaic (ITRPV) Eighth Edition 2017. However, p-type cells can suffer from light-induced …
