N-type silicon-based solar cell test dispels myths on efficiency and degradation

  • N-type silicon-based solar cells are increasingly being used for achieving high efficiency and lower degradation.
  • In order to study and compare the light induced degradation of N-type panels with P-type panels in the real world condition, an investigation had been conducted by a third party testing institution CGC ( China General Certification) on generation performances, degradation (LID) and other electrical properties of n-type TOPCon solar modules are compared with those of p-type PERC modules.
  • The 12-months (July 1,2022 – June 31, 2023) outdoor experimental results shows the yield gain of Jinkosolar’ s N-type TOPCon modules is 4.8% over P-type PERC modules.
  • One of the critical causes for the gain are interpreted by lower First-year degradation of N-type’ s 0.65% versus 1.72% of P-type. 

JinkoSolar’s pioneering collaboration with the prestigious CGC has unveiled the extraordinary advantages of N-Type modules in real-world settings.

Here are the fast facts:

  • Duration: July 1, 2022, to June 31, 2023 Power Generation Performance: Jinko N-type bifacial module outperformed 4.80% higher relative performance Jinko P-type bifacial module
  • Relative performance:  Jinko N-type had 4.80% higher total effective hours compared to Jinko P-type
  • Operating Temperature: Maximum operating temperature of Jinko N-type was 0.05°C lower than Jinko P-type First-Year Power
  • Degradation: Jinko N-type: 0.65% (Astonished Low LID) Jinko P-type: 1.72%

Green Building Africa promotes the need for net carbon zero buildings and cities in Africa. We are fiercely independent and encourage outlying thinkers to contribute to the #netcarbonzero movement. Climate change is upon us and now is the time to react in a more diverse and broader approach to sustainability in the built environment. We challenge architects, property developers, urban planners, renewable energy professionals and green building specialists. We also challenge the funding houses and regulators and the role they play in facilitating investment into green projects. Lastly, we explore and investigate new technology and real-time data to speed up the journey in realising a net carbon zero environment for our children.
