What are the advantages of N-type modules?
N-type modules are photovoltaic modules assembled using N-type solar cells. N-type solar cells are doped with small amounts of elements with a valence of 5, such as phosphorus (P), antimony (Sb), and others, during the cell doping process.
When the atoms of these 5-valence elements replace certain silicon atoms in the silicon lattice, they provide extra electrons, making the electron density in the module much higher than the hole density. The more free electrons there are, the lower the resistivity, which enhances the module's electrical conductivity.
Advantages of N-type Modules:
- N-type modules have a higher bifaciality, providing higher energy yield in power plants with high ground reflectivity.
- N-type modules have a lower temperature coefficient, meaning they are less affected in high-temperature environments.
- Given the same total output power, N-type modules generate more energy over their entire lifespan, with a lower degradation rate and higher efficiency.
- N-type modules respond better to spectra under low light conditions, allowing for longer effective operating times.
Overall, N-type modules offer better economic benefits, but their price is relatively higher.
This concludes the introduction by Hengyuantai on the advantages of N-type modules.
