PVTIME – Silfab Solar, a US-based photovoltaic module manufacturer, has announced the acquisition of a patent portfolio for back-contact (BC) solar cell technology from EnPV, a solar research firm and subsidiary of German energy company EnBW. The move aims to bolster Silfab’s development of high-performance solar solutions tailored to the American market.

The portfolio includes the Selective Area Back Contact (SABC) technology, which Silfab highlights for enabling precise alignment during cell and module production while enhancing electrical performance. EnPV notes that SABC is designed as an upgrade to TOPCon cell technology, featuring a production process that costs less than TOPCon, adapts easily to existing TOPCon lines, and offers greater efficiency and sophistication than traditional back-contact manufacturing methods.
Paolo Maccario, President and CEO of Silfab, stated that the SABC technology was purposefully engineered for the US market. Acquisition of the cutting-edge patents and intellectual property would allow the company to develop next-generation solar modules for its Silfab Elite series and future product lines. This ensures continued delivery of high-quality, high-performance modules manufactured in the US, while preserving strategically important innovations from Europe and America.
Silfab is currently establishing a TOPCon solar cell manufacturing plant in South Carolina, having secured multiple funding rounds for the project. While construction has been delayed by local opposition, the SABC technology is expected to enhance the plant’s capabilities upon operation, solidifying Silfab’s role in driving domestic renewable energy innovation.
