HJ Solar Support Material Price List

What is HJT solar panel?

With excellent photoabsorption and passivation effects, HJT has outstanding efficiency and performance, which make HJT solar panel as one of the technologies to improve the conversion rate and power output to the highest level, and also represent the trend of the new generation of solar cell platform technology.

Which material is used for HJT solar cells?

There are two varieties of c-Si, polycrystalline and monocrystalline silicon, but monocrystalline is the only one considered for HJT solar cells since it has a higher purity and therefore more efficient. Amorphous silicon is used in thin-film PV technology and is the second most important material for manufacturing heterojunction solar cells.

What is the difference between standard and HJT solar cells?

Standard (homojunction) solar cells are manufactured with c-Si for the n-type and p-type layers of the absorbing layer. HJT technology, instead, combines wafer-based PV technology (standard) with thin-film technology, providing heterojunction solar cells with their best features.

How much do heterojunction solar cells cost?

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.

What is HJT bifacial solar?

HJT technology was first developed in the early 1990s, but it became popular these last decades, which explains the 5% market share and higher production costs, but this is only a temporary setback that is expected to be surpassed in the near future. The structure of bifacial panels is similar to the heterojunction solar panel.

What challenges do HJ solar cells face?

HJ solar cells pose specific challenges to equipment manufacturers in printing parameters, thin wafers handling and thermal process window. Applied Materials offers a dedicated version of the Tempo Presto metallization line designed explicitly for HJ cells with multiple solutions for drying ovens and two alternative designs for curing ovens.
