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.
In accordance with the data presented, possibilities were found to increase the output characteristics by improving the design of the contact grid of solar cells and modifying the structure of heterojunction solar cells.
In the first design version of these solar cells, the heterojunction was formed by using the flat n-type crystalline silicon wafer with a thin layer of p-type amorphous hydrogenated silicon (a-Si:H) deposited on its surface . The efficiency of this structure reached 12.3%.
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.
Classification of Heterojunction Solar Cells Doping differentiates these solar cells into n-type and p-type cells: N-type cells use phosphorous-doped c-Si wafers which provide additional electrons for negative charging and make them resistant to boron-oxygen-induced efficiency reduction.
3.1. Si heterojunction solar cell based on doped amorphous Si films 3.1.1. Development history: from 13% to 26.7% Si heterojunction (SHJ) solar cells consist of the happy marriage of c-Si as an absorber layer, with thin-film Si for the selective-contacts of both polarities.
