Semprius, a Durham semiconductor startup that is building a solar panel manufacturing facility in Henderson, announced Thursday that it has raised $3 million in additional funding from a group of investors that includes Chapel Hill-based Morgan Creek Capital Management.
The private company has already raised more than $30 million in venture funding, including a $20 million round that closed in July. Corporate giant Siemens, a leading builder of solar farms, acquired a 16 percent stake in the company in June.
Other investors in this latest round include the Illinois Emerging Technologies Fund and In-Q-Tel, an investment firm affiliated with the CIA.
Semprius also announced Thursday that Gregory Wolf, president of Duke Energy Renewables, has joined the company's board of directors.
Semprius employs 38 people in Research Triangle Park.
