Best PV CELLS - HJT Technology?

How To Choose Best HJT Solar CELL?

HJT (Heterojunction) technology is a superior solar cell that generates energy from both sides. This bi-facial cell combines the advantages of N-type crystalline silicon (c-Si) with the excellent absorption and passivation characteristics of amorphous silicon (a-Si: H).

The N-type c-Si makes HJT cells immune to (LID) while the TCO coating protects the cell from (PID) on both sides of the cell. As a result, HJT cells generate a higher energy yield while exhibiting a lower temperature coefficient than conventional solar cells.

24.5% max. Cell Efficiency

Heterojunction technology plus state of art automatic production line ensure one of the best in class M6 efficiency.

high Performance N-Type Wafers

Thin-film technology with an n-type structure guarantees no LID&PID effects and the lowest power loss after 30 years.

HJT Solar CELL Advantage - HUASUN

Huasun HJT solar cell

Up to 6.75W Power

HS-9BB-M6 HuaSun solar cells can produce even 6,75W energy from each cell. Additional HJT provides the highest bifacially >90%.

Leading temperature co-efficient

Only -0.26%/C is one of the best results in the PV industry. Less power loss as temperature rises is one of the biggest advantages of HJT Cell.

HJT Solar Cell Review

Heterojunction CELLS Ranking

How to choose the Best Solar CELL?

Before the final decision important is to answer of questions below:

Where solar panels will be mounted? For roof installation mostly size and weight have very important meanings. HJT Cells perfect fit for installation with not too much space because of higher energy yield than standard PERC cells.

How big an investment is planned? LCOE and BOS cost in utility forced to chose the strict category of modules. HJT Solar cell thanks to zero PID&LID and natural high bifaciality helping improve ROI.

Quality and fewer problems in the future or cost-cutting and risk? HJT from the beginning increase costs, but low degradation and best performance gives additional profits for 30 years.

Nice look or highest power production? Hjt gives both even in full blacks panels. Additional heterojunction cell has stable color on all modules surface.

HJT with a natural bifacial high rate is perfectly compatible with Glass Glass modules gives the highest anti-fire protections. 

Bifacial or front side only? Even on the roof, bifacial modules give extra power, and when the cost is similar better is choose front&rear side production power.

Geographical localization analysis – why it’s important? In the hot area, the temperature coefficient is crucial (HJT has the best in comparison to all other technologies). In small solar radiation places and cloudy or foggy regions very important is to efficiently produce power in the low radiance (HJT has the best solar abilities).

HJT Advantage for utility-scale projects?

Big investments project like solar farms and utility-scale solar power plants, need to generate profit and have a high ROI. 

HJT technology compares to PERC ensures:

1. Greater performance potential and energy yield.

2. Better Bifacial Index, HJT solar module/cells offer more than 92% on the rare side.

3. HJT Cell takes advantage of this by building solar cell in three different layers of PV materials. The middle layer of N-type mono silicon completes most of the work of converting sunlight into electricity.

4.Lower temperature coefficient, low light performance (better high temperature performance).

Overall Decision Factor

Efficiency of solar Cell is key factor. HJT technology has best serial producing efficiency on average level 24.5%
Leading Co-Efficient -0.26%/C
Bifaciality Index especially in hJT is on top level > 90%
Modern M6 cell size ensure long time Durability
High Power HJT Solar Cell up to 6.75W
N-Type Heterojunction Solutions, ensure best Performance and no failures
9BB and 12BB construction solution for better performance
Current(Isc) 0.055% and Voltage(Voc) -0.27%

Feature of a good PV Modules&Cell?

HJT efficiency can achieve even 27%. But usually producers like HuaSun or Jinergy use Heterojunction solar cells with 24%-24,5% efficiency. Compare to PERC Cell, HJT can achieve even 20% more power.

HJT solar panels have the best efficiency in serial production. Scope of it is between 21%-22,5% with R&D plan even to 26%. HJT module has the best performance and most reliable characteristic resistance for most common fail from all over solar technology.

HJT solar Panels with 120 cells have a scope of power between 370W-390W and for 144 cells 425W – 470W. At the end of 2021 Power of HJT modules will achieve >500W and in soon future will be >600W.

HJT technology ensures a long safe warranty for 30 years of production and 12 -25 years for a panel, depends on the producers. It’s more approx. 5 years than common PERC panels.
