Advantages of Topcon solar cells:

Higher photoelectric conversion efficiency: The conversion efficiency of Topcon cells is usually higher than that of PERC cells, with an efficiency of 24% or more, which means that more electricity can be generated in the same area.


Reduced surface recombination loss: By using tunneling oxide layer and polysilicon contact technology, the recombination loss of electrons on the surface of the cell is effectively reduced, thereby improving the overall performance.


Better temperature coefficient: Topcon cells perform well under high temperature conditions, and their low temperature coefficient means less energy loss under high temperature environment, which is suitable for hot climate areas.


Longer service life: Due to its structural design and material optimization, Topcon cells have better anti-attenuation ability and can maintain high output power for a long time.


Bifacial power generation: Topcon cells can absorb light through the front and back of the cell, which increases the overall power generation, especially under the condition of good reflection site, bifacial power generation can significantly increase the power output.


Better anti-PID performance: Potential-Induced Degradation (PID) is a common aging problem of solar cells. Topcon cells have stronger anti-PID ability through optimized design.

Luan Full-black JKL108-B-(420-440)NB solar panel uses TOPCON solar cells and adopts double-sided power generation technology. It has the advantages of high efficiency, low temperature attenuation and long life. It is an excellent choice for improving the overall power generation efficiency in the photovoltaic industry.


Application areas of Topcon batteries:

Large photovoltaic power stations: Topcon batteries are particularly suitable for large-scale ground-mounted solar power stations and photovoltaic farms due to their high efficiency in power generation and lower attenuation rate.


Commercial and industrial rooftop photovoltaic systems: The high efficiency of Topcon batteries makes them an ideal choice for photovoltaic systems on corporate and industrial buildings, helping to achieve more power output on limited roof areas.


Residential rooftop photovoltaic systems: For home users who need to optimize energy output, Topcon batteries can provide homes with higher energy self-sufficiency and reduce electricity bills.


Bifacial photovoltaic systems: Because Topcon batteries have bifacial power generation capabilities, they are suitable for projects with good reflective environments, such as reflective material ground or floating photovoltaic power stations on the water.


High temperature or extreme environments: In areas with high temperatures or harsh climatic conditions, the low temperature coefficient and high efficiency anti-attenuation characteristics of Topcon batteries give them advantages in these environments.
