6 FAQs about [Heterojunction battery cost reduction]

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.

Can a reduction in paste consumption reduce the cost-advantage of SHJ cells?

A reduction in paste consumption and replacement of silver with copper paste in SHJ cells could alleviate the problem and make the cost-advantage of SHJ cells less dependent on their efficiency advantage. Our prospective analysis indicates this.

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.

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.

What is the conversion efficiency of HJT cells?

The average conversion efficiency of the cell was 25.23%, and the maximum conversion efficiency of a single cell reached 25.69%, once again breaking the company’s cell production efficiency. It is reported that the factory’s HJT cells adopt bifacial microcrystal technology combined with silver copper paste.

Does silver substitution reduce module cost?

Our results show that substituting silver with copper could decrease module cost by an additional 4-7% for SHJ modules, or 6% for c-Si modules. Copper offers similar conductivity, at only a fraction (~2%) of the cost compared to silver. The supply of copper is less constrained, although not impervious to price volatility.
