Improving n-type TOPCon solar cells
Scientists in China have studied the formation of contacts in tunnel-oxide passivated contact (TOPCon) solar cells, and the role of high-temperature annealing processes on the quality and performance of cells. Their findings could open up pathways for scientists looking to squeeze even more efficiency out this rapidly growing cell technology.
Degradation and regeneration in polysilicon passivation layers
Scientists in Australia took a close look at the long-term performance of passivation layers in silicon solar cells, and discovered a surprising process of degradation and regeneration at work within the material. The results could have implications on the processes used in industrial scale solar cell production.
