  • TOPCon mass production shows great potential
    Dec 10, 2020 TOPCon mass production shows great potential
    TOPCon mass production shows great potential Commercialized solar cells aim to achieve over 24% efficiency in the near future. Since PERC cell gradually approaches its efficiency limit, TOPCon solar cell is regarded as the most promising technology to be the major product in the next solar cell generation which can replace PERC cells. As technology of solar cell tends to be mature, the reduction of the cost of Si, glass, installation system and mounting rack is very difficult. In the future, the reduction of LCOE of solar energy depends on the increments of solar cells’ efficiency. Based on the current cost, 1% efficiency increment will reduce 2.82cents/Wp. Compare with PERC cell, TOPCon cell has higher potential on efficiency and stablility. LID and LeTID are always a big problem of PERC cells. However, the TOPCon cell doesn’t have the risk of LID and LeTID due to the features of N-type c-Si. Furthermore, the efficiency limit of TOPCon cells is around 28.7% which is much higher than 25% of PERC and 27.5% of HJT. It is very close to ideal efficiency limit of c-Si, 29.43%. Thus, TOPCon cell has higher potential to develop. In the past few years, had great achievenments on N-type TOPCon solar cell. The efficiencies of TOPCon solar cells reach 24.5%. The new technology, J-TOPCon 2.0, apply the original POPAID (Plasma Oxidation&Plasma Assisted Insitu-doping Deposition) technology. Compare with J-TOPCon 1.0, 2.0 reduces the processing steps and achieve the higher efficiency and yield. J-TOPCon 2.0 curtail 3 manufacturing processing steps. The single-side surface poly-Si deposition and doping of poly-Si can be completed in one step which can further decrease the cost. J-TOPCon 2.0 achieves 24.5% solar cell efficiency by omitting the etching step of wrap-around Poly-Si which avoid the damage of pyramids of the surface. TOPCon module produces more electricity per watt compared with p type. Each 10W increment on the module will bring 0.05RMB/W premium. In the future, the LCOE of TOPCon modules will be continuing reducing to achieve the same cost of PERC modules.

  • 23.5%! NTOPCon battery mass production efficiency hits a new high!
    Mar 16, 2020 23.5%! NTOPCon battery mass production efficiency hits a new high!
      23.5%! NTOPCon battery mass production efficiency hits a new high!   The conversion efficiency of NTOPCon high-efficiency double-sided solar cells in mass production reached 23.5%, which once again refreshed the N-type cell mass production efficiency, laying a solid foundation for the further popularization of N-type photovoltaic products.   The efficiency breakthrough is based on the N-type 158 square silicon wafer, double-sided power generation design, by optimizing the boron expansion process and redesigning the matching metallization process to increase the mass production efficiency to 23.5%, and the highest single-chip efficiency 23.8%. Compared with the 23.2% at the end of last year, the efficiency has increased by 0.3%, and the effective output has increased by 35%. Under the condition of no cost increase, the effect of improving efficiency and reducing costs is significant.
