6 FAQs about [Heterojunction Cell Low Temperature Process]

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 are the advantages of silicon heterojunction solar cells?

How do heterojunction solar cells work?

In the case of front grids, the grid geometry is optimised such to provide a low resistance contact to all areas of the solar cell surface without excessively shading it from sunlight. Heterojunction solar cells are typically metallised (ie. fabrication of the metal contacts) in two distinct methods.

Is low-temperature soldering suitable for SHJ solar cells?

Since the passivation by the amorphous silicon layers of SHJ cells cannot withstand temperatures above 250 °C [7, 8], low-temperature soldering is considered as a suitable technology. The main challenge is to overcome the known weak adhesion between metallization paste and wafer surface, observed after soldering on SHJ solar cells .

What is a heterojunction IBC cell?

A Heterojunction IBC cell is often abbreviated to HBC. A HBC structure has several advantages over conventional SHJ cells; the major advantage is the elimination of shading from the front grid, which improves light capture and hence short circuit current density .
