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.

HJT Solar Cell Review
Heterojunction CELLS Ranking
Heterojunction (HJT) solar panels are a promising technological development in the solar energy industry. HJT solar cells are able to combine the benefits of crystalline silicon and film silicon technology. This results in exceptional light absorption and passivation effects.
Compared to traditional Passivated Emitter and Rear Contacts (PERC) technology, HJT solar cells have shown to be superior in terms of efficiency and performance. The HJT solar cell technology has been identified as a leading battery technology, offering significant improvements in conversion rate and power output.
HJT solar panels also exhibit a bifacial structure, effectively improving the backside power output of module products and increasing power generation income. The low-temperature coefficient helps maintain stable power output performance even in high-temperature environments. Furthermore, the exceptional power output capacity under weak light conditions extends the duration of power generation and further advances overall power generation income.
Ultra-High Conversion Efficiency of Heterojunction Solar Cells
Heterojunction (HJT) solar cells exhibit excellent performance due to the use of intrinsic amorphous silicon thin films as passivation materials. These thin films minimize the loss of minority carriers’ lifetime within the contact area, leading to a substantial increase in the open circuit voltage to 750mV. As a result, HJT solar cells can achieve a power conversion efficiency of up to 25% initially. By implementing double-sided microcrystalline, the doping efficiency and transmittance of the thin films are further enhanced, which contributes to a significant improvement in current density and an overall increase in the cells’ conversion efficiency by more than 25.2%. Consequently, HJT solar cell modules can deliver a power output of 710W+. These findings demonstrate the potential for HJT technology to improve the efficiency and performance of solar energy systems.
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
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.
