    Heterojunction (HJT: Heterojunction Technology) combines the advantages of crystalline silicon and amorphous silicon thin-film technologies, offering excellent light absorption and passivation properties. It outperforms PERC technology in both efficiency and performance and is currently one of the current leading technologies in the solar industry for increasing conversion rates and power output to the highest levels.

    High Bifaciality Solar Modules

    HJT cells are designed with a symmetrical structure and an efficient conductive grid, enabling an impressive power generation capability of over 95% on the rear side. This innovative design significantly outperforms traditional PERC and TopCon technologies, offering a notable increase of 10% to 35% in power generation gain from the rear side.

  • HJT LEID

    Low Attenuation

    Due to the absence of charging possibilities on the surface of HJT cells, there are no LID (Light Induced Degradation) and LeTID (Light and Elevated Temperature Induced Degradation) effects. The power generation capacity of heterojunction solar panels degrades by no more than 11.1% over 30 years, resulting in a more stable power generation capacity throughout their entire lifespan.

    HJT-PID

    No PID Effect

    The TCO (Transparent Conductive Oxide) thin film possesses conductive properties that prevent the surface from generating polarization phenomena for charges, thereby structurally avoiding PID (Potential-Induced Degradation).

    Excellent Power Generation In Low-Light Conditions

    HJT cells incorporate an intrinsic amorphous silicon hydride (i-a-Si:H) layer between the crystalline silicon and doped thin-film silicon, effectively passivating the defects on the surface of crystalline silicon. As a result, heterojunction solar cells have a higher open-circuit voltage than conventional cells, a broader spectral absorption range, and power generation starts quicker under low-light conditions .

  • Super Abundant Busbars

    More and finer busbars achieve fewer busbar shadings and shorter current transfer distances, reducing resistance, enhancing current collection, and further improving tolerance towards micro cracks, busbar breaks.

    Ultra-low Temperature Coefficient

    Compared to PERC and Topcon cells, heterojunction cells have a lower temperature coefficient (-0.24%/°C), which makes their power generation performance more stable at elevated temperatures and suffers lower power losses.

    Non-Cutting Cell Process

    Non-cutting cell processing, which involves complete half-cell configuration, can minimize the impact of micro cracks and potential damage.

    Low-Temperature Process

    HJT cells, due to the use of silicon-based thin films to form a p-n junction, have soldering process temperatures below 250 degrees Celsius. This reduces thermal stress caused by high temperatures and minimizes heat damage to the solar cells.

    High Flexibility

    The unique cell structure of HJT solar panel significantly enhances the cell’s exceptional flexibility, reducing the risk of micro cracks during transportation, installation, and other processes, thereby improving the reliability of the entire solar system..

    30-year Product Warranty

    The HJT solar panel is equipped with weather-resistant, corrosion-resistant, and wear-resistant double-sided glass and POE encapsulation, enabling a 30-year product and performance warranty.
