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.
Heterojunction solar cells (HJT), variously known as Silicon heterojunctions (SHJ) or Heterojunction with Intrinsic Thin Layer (HIT), are a family of photovoltaic cell technologies based on a heterojunction formed between semiconductors with dissimilar band gaps.
A band diagram of the standard HJT solar cell is sketched in Fig. 1b .The i-a-Si:H film, as a buffer layer, enables a low c-Si surface recombination via excellent chemical passivation .
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.
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.
