A heterojunction is a junction between different materials or between the same materials, but with different crystal structure. Junctions between differently doped regions of the same semiconductor material are called a homojunction, while a junction between two different types of materials is called a heterojunction
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.
01. Homojunction: Is a semiconductor interface that befalls within layers of alike semiconductor material. These materials have similar band gaps but typically have unusual doping. Junctions between differently doped regions of the same semiconductor material are called a homojunction.
heterojunction means the device consist of two or more junctions based on two or more difference semiconductor materials with difference doping (intrinsic and extrinsic) homojunction- silicon pn junction , here they have same band gap.
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.
