Silicon heterojunction solar cells (SHJ) is a promising candidate for cost-effective high-efficiency solar cells. The high performance is driven by a superior surface passivation provided by the solar cell structure where a thin silicon amorphous buffer layer separates the bulk from the highly recombinative metallic contacts.
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.
The prominent examples are low-thermal budget silicon heterojunction (SHJ) solar cells and high-thermal budget tunnel-oxide passivating contacts (TOPCon) or doped polysilicon (poly-Si) on oxide junction (POLO) solar cells (see Fig. 1 (e)– (g)).
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.
The term heterojunction derives from the fact that the junction P-N is formed using silicon with two different morphologies, i.e. the absorber is n -type crystalline silicon (c-Si) and the p -region is formed by p -doped amorphous silicon (a-Si). The competitive advantages of SHJ cells are:
Its double-heterojunction scheme is considered as an ideal solar cell structure for carrier-selective passivating contacts . In SHJ solar cells, Phosphorus (P)-doped and Boron (B)-doped silicon thin films are utilized to extract the photogenerated electron and hole carriers from the bulk crystalline silicon (c-Si) wafer, respectively.
