What are HJT Solar Panels?

HJT Solar Panels is Heterojunction solar cells that combine two different cell technologies into one cell crystalline silicon cell sandwiched between two layers of amorphous. This combination increases the efficiency of the cell’s conversion of light into electricity making it one of the most efficient solar cells currently available. HJT Solar Panels where first founded by SANYO Electric in 1980s which recorded efficiencies of 21% at the time which was shocking to the huge potential of solar panels making HJT Solar cells a strong pillar in today’s solar energy hype. Also, there are predictions that the HJT Solar Panels will have around 70% market share by 2030.

What are the advantages and disadvantages of HJT Solar Panels?

Advantages

  • 1-Higher efficiency: HJT Solar Panels have higher efficiency than all other types that reaches 21% and expected to reach 30% in the coming years making it very competitive technology in the market.
  • 2-Lifetime: HJT Solar Panels can reach a lifetime of 30 years and expected to exceed this period as the technology develops further.
  • 3-Cost: HJT Solar Panels are cheaper as they use amorphous layers that are much cheaper than other materials used in normal silicon cells.

Disadvantages

  • 1-Manfacturing equipment: HJT Solar cells use very expensive manufacturing equipment to produce such cells in the required quantity which will need large investment cost to setup a production line for HJT Solar Panels.
  • 2- Technology Development: HJT Solar Panels are very fast in the technology development which makes it very hard for manufacturers to produce large batches because as they start producing a new developed HJT is ready to be implemented.

What are the use cases of HJT Solar Panels?

  • 1-un-even surfaces: HJT Solar Panels have the flexibility making them suitable for different kinds of applications that don’t have even surface or need to be bent somehow.
  • 2- rooftops: HJT Solar Panels are used all types of rooftops either homes or industrial because they are more efficient & their shape is non-disturbing appearance on the rooftop it is installed on. Compared to the normal crystalline solar cells that always look very odd on any rooftop.
