The working principle of heterojunction solar panel under photovoltaic effect is similar to that of other photovoltaic modules. The main difference is that the technology uses three layers of absorption materials and combines thin film and traditional photovoltaic technology.
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 basic difference in the carrier collection for both homo-junction and hetero-junction solar cells lies in the following fact. At a distance from the surface in both cases, the light intensity and collected carriers are found to be more improved for hetero-junction solar cells.
The following table compares the essential features of bifacial and heterojunction (HJT) solar PV modules: Absorb light from both the front and back sides. A layered structure improves the separation of electron-hole pairs for higher efficiency. Achieve over 30% efficiency. Achieve up to 26.7% efficiency.
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.
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.

Principle of photovoltaics
Most ideal heterojunction solar cells expect both the p and n regions to have the same doping concentration and that there is no inter-diffusion of carriers between them. However, in reality, the doping concentration is deliberately kept higher to reduce the resistance in the surface layer, which causes most of the hetero-junction solar cells ...
