Heterojunction technology (HJT) is a N-type bifacial solar cell technology, by leveraging N-type monocrystalline silicon as a substratum and depositing silicon-based thin films with different characteristics and transparent conductive films on the front and rear surfaces respectively.
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.
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.
Heterojunction technology is currently a hot topic actively discussed in the silicon PV community. Hevel recently became one of the first companies to adopt its old micromorph module line for manufacturing high-efficiency silicon heterojunction (SHJ) solar cells and modules.
They are a hybrid technology, combining aspects of conventional crystalline solar cells with thin-film solar cells. Silicon heterojunction-based solar panels are commercially mass-produced for residential and utility markets.
Heterojunction solar cells are compatible with IBC technology, ie. the cell metallisation is entirely on the back surface. A Heterojunction IBC cell is often abbreviated to HBC.

The Al-alloyed back-surface field (Al-BSF) solar cell, 11 depicted in Figure 1 B, was the mainstream cell technology in production for many years until PV manufacturers switched to the passivated emitter and rear cell (PERC) technology for realizing higher efficiency silicon modules. The PERC device architecture, 12 also shown in Figure 1 B, was developed to …
