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.
Silicon heterojunction (SHJ) solar cells have reached high power conversion efficiency owing to their effective passivating contact structures. Improvements in the optoelectronic properties of these contacts can enable higher device efficiency, thus further consolidating the commercial potential of SHJ technology.
Heterojunction solar panels are assembled similarly to standard homojunction modules, but the singularity of this technology lies in the solar cell itself. To understand the technology, we provide you with a deep analysis of the materials, structure, manufacturing, and classification of the HJT panels.
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 can be classified into two categories depending on the doping: n-type or p-type. The most popular doping uses n-type c-Si wafers. These are doped with phosphorous, which provides them an extra electron to negatively charge them.
