Silicon Heterojunction Technology (HJT) Solar PV Cells

HJT, or Silicon Heterojunction Technology, is a cutting-edge approach to solar PV cell design. It utilizes a unique structure where both the emitter and back surface field (BSF) are formed by depositing ultra-thin layers of amorphous silicon (a-Si:H) on meticulously cleaned monocrystalline silicon wafers. These wafers are remarkably thin, typically less than 160 micrometers, and designed to optimize the generation of electrons and holes upon exposure to sunlight.

Key Features of HJT Solar PV Cells

HJT offers several compelling advantages over traditional solar cell technologies:


  • High Cell Efficiency:

HJT cells boast the potential to achieve efficiencies exceeding 24.8%. This is achieved through a combination of phosphorus fettering and a nano-crystalline process.


  • Superior Performance in Hot Climates:

HJT cells exhibit an ultra-low temperature coefficient. This translates to maintaining higher power output even in scorching temperatures, a significant benefit in many regions.


  • Unmatched Durability:

Unlike some solar cells, HJT technology experiences minimal degradation over time. This is due to the absence of light-induced degradation (LID) and potential induced degradation (PID).


  • Maximum Module Power:

HJT modules are engineered to maximize power output. This is achieved through a combination of factors:


  • Half-cell design:

This approach minimizes power loss due to mismatch between individual cells within the module.


  • Bifacial construction:

HJT cells can capture sunlight from both sides, further boosting overall power generation.


  • Lower Levelized Cost of Energy (LCOE):

HJT’s high efficiency, durability, and power output all contribute to a lower LCOE for solar power systems.


Applications of HJT Solar PV Cells

HJT’s impressive features make it suitable for a wide range of applications:


  • Rooftop solar panels:

HJT’s high efficiency is ideal for maximizing power generation in residential and commercial rooftop installations.


  • Utility-scale solar farms:

Large-scale solar farms benefit from HJT’s ability to generate more electricity per unit area.


  • Building integrated photovoltaics (BIPV):

The thin profile and potential for bifacial light capture make HJT cells well-suited for integration into building materials.


Summary of 210mm HJT Solar PV Cell


  • Larger and More Efficient Solar Cells:

Scientists have developed a new type of solar cell called HJT that is bigger than usual. This bigger size allows solar panels to use fewer cells overall.


  • Benefits of Bigger Cells:

Having fewer cells in a panel can make them easier to manufacture and also reduce energy loss. On top of that, the larger size of the HJT cells can also lead to more power generation per panel.


  • The Future of Solar Energy:

In short, HJT solar PV cells are a big step forward in solar technology. They are very efficient, durable, and work well in hot weather.
