Plating for HJT Solar Cells
Laser Pattern Transfer Printing And Copper Plating Are 2 Promising Approaches For Improving Metallization Of HJT Cells
In our recent articles on HJT cell processing we also mentioned several approaches explored in metallization of HJT (see Developments In Metallization For HJT). We now look further into alternate methods to improve the metallization process.
Developments In Metallization For HJT
Low Temperature Metallization Paste Solutions For HJT And Perovskite Tandem Cells Aim To Reduce Costs And Improve Efficiency
The metallization process and role of screen printing technology are being discussed in this article of our series on HJT solar technology.
Putting Contacts On Topcon Cells
For Metallization Of TOPCon The Paste Usage Doubles, While Rena Promotes Plating To Reduce Costs
Metallization is the tricky part in the manufacturing process of TOPCon cells. As with PERC, 2 influencers of costs are the usage of silver pastes and the deposition process itself.
