Boviet Solar To Explore TOPCon & HJT
Boviet Solar Launches Research Into N-TOPCon, HJT & 600W+ Solar Modules
Vietnamese-American PERC based solar module maker Boviet Solar plans to now venture into N-TOPCon and heterojunction (HJT) solar cell technology, as well as undertaking development of 600W+ module, as part of its new research and development (R&D) initiatives.
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.
Boron for TOPCon Cells
Boron Diffusion And Annealing Are The Other Important Additional Process Steps Involved In TOPCon Processing
The TOPCon cell manufacturing process involves a few additional steps compared to PERC. While emitter formation is not completely new, it is fairly different from what is done in PERC.
Preparing The Surface For Topcon
Dry And Wet-Chemical Etching Solutions For Surface Preparation Of TOPCon Solar Cell Processing
While the core of TOPCon lies in deposition of tunneling oxide and the polysilicon layer, producing these cells, similar to PERC, does require several processing steps that are worth mentioning, not critical though.
Deposition Options in TOPCon Cell Processing
PEALD From Leadmicro And APCVD From Schmid Are Technologies Used In Deposition Process Of TOPCon Solar Cell Processing
As mentioned in our previous articles on TOPCon solar technology published recently, nearly every know deposition technology in PV is promoted for this silicon solar cell application – and PEALD and APCVD are among those.
25.5% Efficiency For 210mm i-TOPCon Cell
