Austin, Texas – April 21, 2008 — HelioVolt Corporation, a producer of highly-efficient thin film solar energy products, announced today that Louay Eldada, Ph.D., has joined as chief technical officer. A technical leader with proven track record at both small and large companies, Dr. Eldada joins HelioVolt from E.I. du Pont de Nemours & Company (DuPont) where he served as CTO, vice president of technology, vice president of engineering and board director for DuPont Photonics Technologies. In the new position at HelioVolt, Dr. Eldada will direct strategic technology planning and development for the company's advanced thin film solar energy products.

"HelioVolt has consistently hit its milestones for bringing our advanced solar technology to the global energy market, momentum that we aim to sustain as we launch and diversify our product offering," said HelioVolt CEO and founder Dr. BJ Stanbery.
