n-TOPCon Solar Cell Smart Production Line

  Features  

·A layer of ultra-thin silicon oxide and doped polysilicon layer was prepared on the back of the cell, which together formed a passivated contact structure and effectively reduced the surface recombination; 

·By optimizing the metal contact structure on the back, the photocurrent loss is reduced, and the VOC is high, which significantly improves the conversion efficiency; 

·With the advancement of mass production, the investment cost of TOPCon cell production line has been significantly reduced; 

·Compared with PERC cells, TOPCon cells have the advantages of high efficiency, high bifaciality, low attenuation and low temperature coefficient; 

·TOPCon technology is quite mature, highly compatible with the existing PERC production line, easy to upgrade the production line, and has become the mainstream mass production technology.
