Heterojunction solar cells are compatible with IBC technology, ie. the cell metallisation is entirely on the back surface. A Heterojunction IBC cell is often abbreviated to HBC.
Heterojunction solar cells are a recent advancement in the PV market which are addressing common drawbacks of standard modules. It reduces recombination and improves performance in hot climates. Come let us explore more about them. These are also known as Silicon heterojunctions (SHJ) or Heterojunction with Intrinsic Thin Layer (HIT) solar panels.
They are a hybrid technology, combining aspects of conventional crystalline solar cells with thin-film solar cells. Silicon heterojunction-based solar panels are commercially mass-produced for residential and utility markets.
Applications of heterojunction solar technology in utility-scale settings can offer efficiency from 25 to 30% efficiency. However, the pros of HJT come with cons too which are listed below: Outperform standard solar cells by converting more sunlight into electricity.
Don’t be confused about what is heterojunction technology. These are built on an N-type monocrystalline silicon substrate and have non-doped amorphous silicon layers (i-a-Si:H) placed on top which improves their efficiency and performance. These cells are made of three key materials: 1.
According to current designs, SHJ modules cost 0.48-0.56 USD/W compared to 0.50 USD/W for conventional modules. Note: The heterojunction solar cell prices may vary due to market fluctuations, brand differences and regional factors.
