Vijit Sabnis, one of the founders of concentrated photovoltaic (CPV) semiconductor startup Solar Junction, now works for Khosla Ventures as a venture partner, according to his LinkedIn profile. In July of last year, we reported that Solar Junction had been acquired by Saudi entity King Abdulaziz City for Science and Technology and one of its investment arms, Taqnia. Last month, Solar Junction announced, "The Committee on Foreign Investment in the United States has approved Taqnia International’s recent investment in Solar Junction Corporation. [...] Solar Junction Corporation, based in San Jose, California, will remain a U.S. company." Mike Wiemer, a Solar Junction founder, has resigned from the firm, according to sources; he notes one of his achievements as having "sold" Solar Junction in a "full acquisition" on his LinkedIn page. Yet another founder, Homan Yuen, has also resigned from the firm. Solar Junction raised more than $30 million from investors ATV, DFJ and NEA. The startup executed on its technical goals, developing record-setting triple-junction solar cells in the lab for CPV applications at a relatively modest burn rate. But building semiconductor components for a systems market that barely exists is not a workable business plan for a VC-funded firm. What will the Saudis do with this science project?
