This Deal Matters: Khosla Places Big Bet on Thin Film Solar
Last week, Greentech Media reported on a deal that took place quietly back in October. In a letter to creditors and shareholders, a financial services firm representing Stion, one of the many struggling producers of Copper-Indium-Gallium-(di)Selenide (CIGS) thin film solar PV cells, disclosed that existing shareholder Khosla Ventures had taken a controlling stake in the company and provided for “an assignment for the benefit of creditors”.
After conventional silicon PV markets experienced a dramatic oversupply and subsequent price crash in the past few years, thin film solar producers, which haven’t yet matched the conversion efficiency of silicon PV and so had been competing primarily on cost, found themselves unable to compete — resulting in several bankruptcies and fire sales. Khosla Ventures’ investment in Stion, which had raised nearly $250 million from investors including Khosla, Braemar Energy Ventures, General Catalyst Partners, Lightspeed Venture Partners, AVACO, and others, is a significant bet that thin film solar can still work. Time will tell, as they say, whether this bet turns out to have been a wise one.
