AI Customer ServiceHeterojunction (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.
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.

1. Crystalline Silicon (c-Si) – Conventional solar panels use them to build homojunction solar cells. They are of two types polycrystalline silicon and monocrystalline silicon. However, monocrystalline is the only one considered for HJT solar cells because of its better purity and efficiency. 2.
In summary, C/Si HJ solar cells provide an avenue towards low-cost but high efficiency photovoltaics. However, due to the inhomogeneities of the carbon-based film during fabrication and the lack of interface passivation, the PCE and active areas are lower than C/Si solar cells.
HJT cells can be designed for monofacial or bifacial usage, which reduces the reasons to compare them against each other since they can be combined to create superior bifacial HJT solar panels. The major difference is that bifacial can use other base technologies differing from HJT technology.
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.
