HelioVolt, which to date has produced mostly press releases for the press and agita for its investors, has raised an additional $19 million from SK Group, Korea’s third-largest conglomerate. SK invested $50 million in the firm in September 2011.

HelioVolt builds monolithically integrated CIGS solar modules and has raised more than $200 million since its founding at the dawn of the last decade. Investors prior to SK included Masdar Clean Tech Fund, Morgan Stanley, New Enterprise Associates, Paladin Capital Partners Fund, Solucar Energia, Sunton United Energy, Texas Emerging Technology Fund, and Yellowstone Capital.

HelioVolt claims in a release, "After several years of limited commercial product shipments from its current facility in Austin, TX, HelioVolt is preparing for global capacity expansion. The company is not yet disclosing information about future factories, though it does acknowledge its intent to expand its product areas to include innovative solutions for residential and commercial applications in addition to utility-scale projects."
