6 FAQs about [HJT photovoltaic panels]
What is HJT solar panel?
Heterojunction (HJT) solar panel, also known as Silicon heterojunctions (SHJ) or Heterojunction with Intrinsic Thin Layer (HIT) solar panel, is a collection of HJT solar cells that leverage advanced photovoltaic technology. HJT cells combine the benefits of crystalline silicon with thin-film technologies.
Why are monofacial HJT solar cells better than heterojunction solar panels?
This three-step process is the reason why monofacial HJT solar cells have achieved solar efficiencies of up to 26.7%. Heterojunction technology is based on traditional c-Si panels, improving the recombination process and other major flaws.
Which material is used for HJT solar cells?
There are two varieties of c-Si, polycrystalline and monocrystalline silicon, but monocrystalline is the only one considered for HJT solar cells since it has a higher purity and therefore more efficient. Amorphous silicon is used in thin-film PV technology and is the second most important material for manufacturing heterojunction solar cells.
What are the advantages and disadvantages of HJT solar panels?
When comparing Heterojunction Technology (HJT), Tunnel Oxide Passivated Contact (TOPCon), and Passivated Emitter Rear Cell (PERC) solar panels across various technical parameters, the following data highlights the advantages of HJT: In terms of bifaciality, HJT solar panels lead with a 95% efficiency, surpassing TOPCon at 85% and PERC at 70%.
Are HJT solar panels reliable?
In terms of temperature coefficient, HJT solar panels stand out with a lower value of -0.243%/°C, indicating reduced sensitivity to temperature variations compared to TOPCon (-0.32%/°C) and PERC (-0.35%/°C). This characteristic contributes to the consistent and reliable power generation of HJT solar panels across diverse environmental conditions.
What is the structure of HJT solar cell?
Structure of HJT solar cell - Source: De Wolf, S. et al. The absorber layer of the heterojunction solar cell encloses a c-Si wafer-based layer (blue layer) placed between two thin intrinsic (i) a-Si:H layers (yellow layer), with doped a-Si:H layers (red & green layers) placed on top of each a-Si:H (i) layer.
