HJT technology introduction

HJT- Heterojunction powerful solar technology – introduction

HJT (high-efficiency crystalline p-n transition silicon) technology is a new approach to harnessing solar energy in photovoltaics. HJT is a type of solar cell that differs from traditional silicon cells in that it consists of two layers of crystalline p-type and n-type silicon placed side by side.

One of the main advantages of HJT technology is its high efficiency, which means that the cell can produce more energy from the same amount of sunlight compared to traditional silicon cells. HJT’s high efficiency is made possible by the use of two layers of p-type and n-type crystalline silicon, which are more efficient at capturing and converting solar energy into electricity.

Power range for HJT modules up to 715W

Super high power output, up to 710W in the lab and 700W in mass production with dimensions of 2384*1303*35mm. Characterization of the cell on an N-type substrate with silicon in amorphous form gives higher efficiency and durability. Which allows you to squeeze more power out of the same size and provide better durability. Actually Mysolar GOLD HJT, Akcome and Huasun produce solar panels of up to 700W.

Efficiency HJT solar panel

High efficiency of solar modules, up to 22.86% for 710W. In general, HJT’s series-produced silicon cells are breaking efficiency records. Thanks to the combination of two types of silicon. In addition, there are development plans for HJT + Perovskite cells.

Lowers degradation rating for solar panels in the market

Lower annual degradation: only 1% in the first year and 0.25% in the second year and each every. This is an extremely key element even in terms of carbon footprint. That is, a technological process that consumes less energy and a longer effective use gives additional bonuses.

Super low-temperature coefficient percent

Lower temperature coefficient: -0.26%/℃, meaning that HJT panels generate up to 3.5% more electricity than general mono-perc panels. In Polish/Swedish/Scandinavian conditions, this is also an important parameter. Our weather windows can be used much better because the intense sun occurs less often and then the high temperature decreases the use of its power. With HJT we will make much more effective use of hot days.

No degradation factors compare to PERC technology

There is no LID effect because the N-type wafer has no B-O(Bor-Oxygen) bond. This is purely a manufacturing disadvantage of PERC vs N-type. This can be defined by impurities, affecting the strength and operation of N cells in this case N + silicon “film”.

Low radiation efficiency solar panels

Much better low-light performance, which contributes to a 1% increase in power. This also includes better production from reflected light. The angle of the sun’s rays affects production. With N and silicon film, the angle matters less by making the production range larger.

Strength and highest reliable

There is less risk of microcracking because the processing temperature of HJT cells is lower than 250℃. Also, the cut and the number of production processes work in favor of HJT’s strength and smaller carbon footprint.

Most powerful bifiaciality in the solar panel market

Significantly higher bifaciality (up to 95%) in HJT cells compared to mono perc cells, meaning that bifacial HJT panels can generate 3.5-6% more power per watt. N-type is a range of 80%-85% bifacial, HJT is 85% -95% and PERC is 70%-75%.

Mysolar HJT Gold longest warranty for product

Longest warranty: 30-year limited product warranty plus 30-year linear performance warranty (@91.75% rated power in 30 years). There is no other technology and only a few companies can compete with Mysolar in this matter
