Semprius has secured another $3 million in financing, including more funding from the investment arm of the Central Intelligence Agency.

The Durham-based company, which focuses on modules utilized in solar power panels, also named a Duke Energy executive to its board of directors.

Among the investors in the latest funding is a new backer for Semprius – Morgan Creek Capital Management.

Other participants were In-Q-Tel, the CIA group that has already helped fund Semprius’ develop-ment, and Illinois Emerging Technologies Fund.

Last July, Semprius said it would build a solar cell plant in Vance County that will employ more than 250 people within five years.

Semprius will invest $89.7 million in the plant and could get up to $18.3 million in state and local grants if it meets investment and hiring targets.

The company has patented a manufacturing process in which semiconductors are printed on glass, plastic or other materials for use in solar panels, liquid-crystal displays, advanced disk drivers and other devices.

Joining the booard is Gregory Wolf, president of Duke Energy Renewables.

“There is a large market opportunity for Semprius as they capitalize on the growing global demand for utility-scale solar,” said Wolf in a statement. “I’m eager to work with this outstanding North Carolina growth company as they accelerate the adoption of solar energy in many key markets.”

In December, a tiny dot of a solar cell made by Semprius won plaudits from a federal testing laboratory for its energy-conversion efficiency.

The U.S. Department of Energy’s National Renewable Energy Laboratory, which helped Semprius with seed money, said it has validated greater than 41 percent efficiency at a concentration of 1,000 suns for tiny cells made by Semprius.

The performance by the 600 micron-wide cells is “one of the highest efficiencies recorded at this concentration,” the lab said.

The new funds will be used in the building of a pilot production plant.

Semprius closed on a $20 million funding round led by Siemens Venture Capital last July. This new funding is an addition to that found, the company said.

“The additional capital, together with our investors’ and board’s support, will help us advance key initiatives to position Semprius for aggressive growth,” said Joe Carr, chief executive officer of Semprius. “In addition, the ability to attract an industry veteran like Greg to join our board is a solid testimonial to the value of the technology we are pioneering.”
