N-TYPE Technology in PV

N-type technology what is it?

Differentiating between the production technology of solar modules can be as simple as it is complicated. In the following text, we will focus more on the simple distinction. The differences between the production technology of P-type and N-type are valid as manufacturers follow different technological paths to compete in terms of efficiency, cost and differentiated propositions. N-Type silicon cells are used in HJT (Mysolar,AKCOME, Jinergy or Risen), IBC and TOPCon technologies. While mono and multi P-type PERCs are being developed, the performance of N-type silicon cells is also increasing (NTOPCon from Jolywood and HJT) and has the potential to become a leading technology in photovoltaics. Mainly thanks:

The world’s highest bifaciality (double-sided production)
The low-temperature coefficient
High efficiency in low sunlight
Very low degradation
The lower temperature at which the N-Type is produced
Shorter production process

What N-Type Technology offer

N-Type Advantage

Zero LeTID&PID

LeTID (Light and Elevated Temperature Induced Degradation) is a failure or defect caused by light and high temperatures. Ntype HJT solar panels are free of it or LeTID has minimum influence on production. TCO film in the HJT module prevents charge accumulation on the surface, resulting in high resistance to PID.

Zero LID

LID effect - what is it about? LID is Light-Induced Degradation, i.e. the phenomenon of rapid but short-term degradation under the influence of solar radiation falling on the cell. The phenomenon is caused by the contamination of silicon with oxygen atoms, which binds boron introduced into the silicon wafers.

Glass Glass COVER

Due to the increased reliability of the double glazing module design, they are expected to degrade only 0.4% per year on average, as opposed to the traditional polymer back layer at 0.7% per year. Therefore. over 30 years of operation, it can be expected to continue to operate at 85% of rated power (some modules already reach over 87% after 30 years).

Bifacial POWER

Due to the technical production and properties of N-type silicon cells, the bifaciality of HJT Solar Panels is the highest on market at 80-95%. PERC bifacial factor is on average level 70%. HJT cells are the best solution for bifacial solar modules. Generally bifacial panels enables 5%-30% energy gain on the back, depending on the factors such as ground reflection, region type etc.

Lowest Temperature Coefficient

HJT (n-type) demonstrates unique advantages in high temperature/high irradiance areas. Compared to the PERC module, HJT features a lower power temperature coefficient and higher output power. It is about 4.5% more efficient in power output than the PERC module under 60℃ operation temperature.

Highest Average Efficiency >24%

Due to the high Minority carrier lifetime of N-type substrate materials, N-type crystalline silicon modules demonstrate better power generation characteristics than conventional P-type crystalline silicon modules under low light. The effective power generation time of HJT is 11.07% more than that of conventional solar modules.

Differences Between HJT and PERC

Differences between HJT and N-Type and PERC Efficiency: The most powerful solar cells currently available on the market are N-type. The main reason for their excellent performance is their longer service life. The technology based on the N base is not susceptible to the so-called Boron-oxygen defect. In the production of Boron-enriched silicon, oxygen can reach a high concentration, and this oxygen creates a region of recombination, called the boron oxygen defect, which harms performance. When using phosphorus-enriched N-type solar cells, this effect does not occur. Moreover, N-type solar cells are less susceptible to metallic silicon contamination. For Jolywood (Ntopcon), Jinergy, AKCOME, and Risen (HJT) modules, this is also a very low annual power loss of a maximum of 1% in the first year and a very low drop of only 0.4% per annum over 30 years.

N-Type: Plus at the top and minus at the bottom

N-type solar cells are constructed the other way around, i.e. N-type silicon serves as the basis of the solar cell. Interestingly, the first solar cell produced by Bell Laboratories in 1954 was a back-contact N-type solar cell. Already in the first years, there was a rapid and significant increase in the efficiency of N-type cells. One for several reasons, gradually, the structure of the P-type cell took a leading role in the history of photovoltaics development. This happened because, in the early years of its development, solar technology was mainly used for space applications. Where the P-type structure has better resistance to radiation in space. Therefore, by directly transferring space solutions, the photovoltaic industry has developed and structured P-type technology.

Why HJT Panels Are The Best?

Best Advantage of N-Type Solar Panels

HJT is considered one of the top cell technologies with highest bifaciality. Higher bifaciality allows more energy yield on the back. Bifacial solar modules Catch and convert solar light fully, so bifacial cell generates 15-30% more power.

Low temperature coefficient and high bifaciality performance allow the HJT module to bring more energy yield. According to the existing power warranty curve, the HJT module has a higher energy production effect.

Module works with HJT cells, which have much lower degradation than PERC panels, more stable and long-lasting power generation. N-type promises to provide the best quality assurance to ensure maximum customer value. Degradation is only 1% in the first year and after 0,25% yearly in 30 years.

Long Warranty for N-Type Panels. 30 years for linear power loss and at least 15 years for product (Mysolar 30 years for product) give N-type modules Top positions in the PV market. In addition, HJT gives a minimal risk of hot spots, zero LID &PID degradation what is crucial to ensure ROI of the PV investment.

frequently asked questions

What is HJT(C-Si wafer) Cell Efficiency?

HJT(ntype) efficiency can achieve even 27%. But usually producers like Mysolar, Akcome and Jinergy use Heterojunction solar cells with 24%-25% efficiency. Compare to PERC Cell, HJT can achieve even 20% more power.

What Is HJT(c-si wafer) Panels Efficiency?

HJT solar panels have the best efficiency in serial production. Scope of it is between 21%-22,53% with R&D plan even to 26%. N-type module has the best performance and most reliable characteristic resistance for most common fail from all over solar technology.

Is HJT with N-type cells Panels are expensive?

HJT solar panels with N-type cells are value for money solutions. Compare with standard backsheet modules, the price for Heterojunction is a little bit more. But compared with Bifacial, glass-glass solar panels, HJT is the best solution and has more advantages worth a few % higher price.

Best Solar Panels for Utility scale?

Higher power, bifaciality, efficient production under extreme conditions, combined with the world’s lowest degradation, no LID and PID effects and a double glass structure (GLASS-GLASS), allows you to generate significant savings over 30 years of use compared to PERC panels.

Advantage of Double Glass Panles?

Glass is the best protection for the silicon cells that are the heart of the photovoltaic module. A cell is a unit that generates electricity, but it is made of a delicate material that needs to be reinforced and secured externally. For this purpose, we have a good ally in the form of solar glass, which, in addition to being transparent, is an electrical insulator.
