Heterojunction battery cost and price

Can silicon heterojunction PV modules reduce production costs?

Silicon heterojunction PV modules can have lower production costs compared to conventional crystalline silicon. High efficiency is essential for low-cost silicon heterojunction modules. There is potential for significant cost reductions in prospective silicon heterojunction PV modules.

Why are SHJ cells expensive?

SHJ cells are expensive primarily because of the high cost of the low-temperature paste used in their processing. The high cost is due to the increased amount of paste required because of its lower as-cured conductivity. This results in higher cell costs for SHJ designs (USD/cell), which is partly offset by the high efficiency of heterojunction technology.

What is the cost of a SHJ module?

The cost of a SHJ module is 0.48–0.56 USD per Watt-peak ( W p).

What is a silicon heterojunction solar cell?

A silicon heterojunction (SHJ) solar cell is a type of solar cell produced from silicon wafers using a low temperature process that does not exceed 200 °C.

Does metallization affect the cost of SHJ modules?

The use of metallization in SHJ modules increases the cost compared to conventional crystalline silicon modules due to the high cost of the low-temperature paste needed for SHJ cell processing and the increased amount of paste required.

Are SHJ modules cheaper than conventional monocrystalline silicon modules?

Our analysis shows that current SHJ modules are comparable in price to conventional monocrystalline silicon modules, but using more expensive materials in SHJ production incurs cost penalties that need high efficiencies to be offset.
