Heterojunction (HJT) means that solar cell is not made with homogenous material like monocrystal cell. HJT is a combination of Moncristal Silicon and amorphous Silicon Thin-film/ Layer. This innovative Idea to combine to kind of Silicon was developed by SANYO with the name “HIT” (Heterojunction with Intrinsic Thin-layer technology). HJT technology combines the best advantage of crystalline silicon N-Type and thin-film giving:
Highest Efficiency and power of solar panels 710W
30 years with only 0,25% annual degradation
N-type & Bifacial Cells cover in Glass glass frame
Differences between HJT and N-Type and PERC Unlike standard (PERC and N Type) crystalline solar cells which are homogeneous devices. Which means that the p-type and n-type semiconductor layers are formed on the same base material. Heterojoint cells, on the other hand, are made by combining two different types of materials. In the case of HJT silicon, the connection is made between the crystalline and amorphous silicon materials.
Sanyo, which is a pioneer of HJT technology. He proposed placing an internal amorphous layer between the enriched surfaces of amorphous and crystalline silicon. This gave rise to the famous and patented "Heterojunction Sanyo" with an "Intrinsic Thin" layer, commonly known as HIT. For practical reasons HIT structure composed of crystalline silicon wafer, typically n-type, disposed between the inner and opposite enriched layers of amorphous silicon deposited at both sides and a transparent conductive oxide (TCO) on top. Almost all existing HJT concepts are based on this template
In some ways, solar cells are really simple. The light shines into them, precipitating electrons from silicon atoms. A cell is built in such a way that electrons are often blocked from returning to the atoms they came from. Instead, they travel through the fine mesh of wires at the top of the cell to the back of the cell and are transformed into electricity as they travel. This is what is done in the P-type solar cell because P is positive (positive) and the solar cell has a positive base that attracts him negatively charged electrons. The exact opposite process takes place in N-type cells. Since the base is negative, the electrons travel from the negative bottom to the positive top.
Up 15% more production in 30 years
UP to 9,3% less construction costs
6,4% lower cost of MC4 and cables
Up to 10.4% lower labor costs
LCOE reduction 4,4%
Up to 20% lower BOS costs
HJT efficiency can achieve even 27%. But usually producers like Acome and Jinergy use Heterojunction solar cells with 24%-25% 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 -30 years for a panel, depends on the producers. It’s more approx. 5 years than common PERC panels.
HJT solar panels 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.
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.
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.
