The difference between p-type and n-type solar panels

The difference between p-type and n-type solar panels

The main difference between P-type and N-type solar panels lies in the semiconductor materials and performance characteristics they use. P-type solar panels use boron doped P-type silicon wafers as the substrate, while N-type solar panels use phosphorus doped N-type silicon wafers as the substrate. The differences in electronic structure and conductivity between these two materials lead to their different performance in photovoltaic effect and efficiency: 

N-type solar panels:

Using N-type silicon material, it has higher electron mobility and fewer impurities.

Usually has higher photoelectric conversion efficiency and lower attenuation rate.

Having better resistance to photo induced attenuation means more stable performance under long-term illumination.

Higher power and higher conversion efficiency. Under standard testing conditions, the conversion efficiency can reach 24.6%, and the solar panel power can reach over 575W.

P-type solar panels:

Using P-type silicon material, the production process is relatively simple and the cost is low.

Although the performance is not as good as N-type solar panels, it is still sufficient to meet the needs in many applications.

The component power can reach over 550W and the conversion rate is 23.5%.

At present, the mainstream product in the photovoltaic industry is P-type solar cells corresponding to P-type silicon wafers. However, with the advancement of technology and the reduction of costs, the market share of N-type solar panels is gradually increasing. The advantages of N-type solar panels make them more advantageous in applications that require higher efficiency and more stable performance.
