Come let us explore more about them. These are also known as Silicon heterojunctions (SHJ) or Heterojunction with Intrinsic Thin Layer (HIT) solar panels. These are a group of HJT solar cells that use advanced photovoltaic technology. Don’t be confused about what is heterojunction technology.
Heterojunction solar panels are assembled similarly to standard homojunction modules, but the singularity of this technology lies in the solar cell itself. To understand the technology, we provide you with a deep analysis of the materials, structure, manufacturing, and classification of the HJT panels.
Standard (homojunction) solar cells are manufactured with c-Si for the n-type and p-type layers of the absorbing layer. HJT technology, instead, combines wafer-based PV technology (standard) with thin-film technology, providing heterojunction solar cells with their best features.

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.
HJT technology was first developed in the early 1990s, but it became popular these last decades, which explains the 5% market share and higher production costs, but this is only a temporary setback that is expected to be surpassed in the near future. The structure of bifacial panels is similar to the heterojunction solar panel.
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.
