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. They are a hybrid technology, combining aspects.

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.
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.
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.
Originally developed by Sanyo in Japan in 1990, this technology has since become a cornerstone of high-efficiency solar cells. To avoid patent issues, various companies have adopted different names such as HJT, SHJ, and HDT, but they all refer to the same core technology. What is an HJT Solar Cell?
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.
The solar industry produced 5GW in heterojunction solar panels in 2019, making HJT technology hold around 5% of the retail market, with the largest manufacturers being Tesla in the US and Panasonic in Malaya and Japan, but this is expected to grow in the future.
