Silicon solar cells on a cleanroom conveyor

Silfab Solar announced on May 20, 2024 that the Department of Energy selected it for awards to advance USA-made solar cells, including a $20 million project to develop next-generation back-contact cells in South Carolina.

The projects

  • The cell project aims for back-contact N-type cells with efficiencies of 26 percent or better.
  • Work will run on a 300-megawatt pilot line alongside Silfab’s main N-type cell production at its new Fort Mill, South Carolina plant.
  • DOE’s share is $5 million, with Silfab putting in $14.9 million, according to DOE’s project listing.
  • A separate $500,000 award will develop building-integrated solar spandrel panels at Silfab’s Washington state plant.

Why cells matter

Most solar modules assembled in the USA still use imported cells. Silfab says the Fort Mill plant will add 1 gigawatt of USA cell production and 1.3 gigawatts of module production, helping close that gap.

“Silfab Solar is leading the way in U.S. integration of innovative solar cells and modules.”
