Assessment of hydrogen-induced contact resistance in TOPCon solar cells
Researchers have looked at how hydrogen-induced contact resistance could help to reduce changes in series resistance, in either TOPCon or PERC solar cells. They said degradation occurs purely at the n-type silicon-to-silver (Ag) contact on both cell architectures.
Longi reports US decision dismissing Hanwha patent claims
The Chinese solar giant today announced a final written decision published by the American authorities which reportedly invalidates Hanwha Q Cells patents. That development appears to have come 12 days after the Korean manufacturer carried out a seizure of a Longi panel shipment in Rotterdam on the basis of the potential for the infringement of Hanwha patents which apply in Europe.
Preventing LID in a 23.83% efficient Longi PERC cell
Australian researchers have unveiled hydrogenation technology to reduce light and elevated temperature-induced degradation in Czochralski silicon PERC solar cells. The developers say the process can minimize degradation without sacrificing performance in cells and modules.
