6 FAQs about [How is HJ solar cell]

What are heterojunction solar cells (HJT)?

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.

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.

What is the difference between standard and HJT solar cells?

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.

What is HJT solar cell structure?

The HJT solar cell structure combines two technologies: a crystalline silicon cell sandwiched between two layers of amorphous “thin-film” silicon. In this approach, thin-film solar has a higher temperature coefficient than crystalline silicon.

How efficient is HJT solar cell?

With a maximum cell efficiency of 29.20%, closely approaching the 29.40% of monocrystalline silicon cells, HJT is widely regarded as the next-generation solar cell technology.

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.
