Fine Line Dispensing Process to apply Narrow Metal Contacts onto Solar Cells

HighLine Technology GmbH is a ISE spin-off from Fraunhofer Institute for Solar Energy Systems with exclusive IP rights to redefine the standard METALLIZATION process to apply the small contact lines made of silver onto Si-solar cells.

With silver costs for metallization as the 2nd most expensive step in solar cell production, the PV industry is being responsible for >10% of the global silver demand. When it comes to cell efficiency, mainstream PERC cells have achieved max 23.5% efficiency and 0.05/kW cost limits.

The promising next step in cell technology/efficiency with Heterojunction cells (HJT) requires more than double the silver laydown compromising industry adoption despite its efficiency benefits above 26%.

Designed to streamline metallization for today (PERC) and future (HJT) cells, HighLine FINE-LINE DISPENSING TECHNOLOGY enables cell producers the precise application of thinner contacts at 25% lower silver needs, 1% efficiency gains and 50% higher throughput.
