Rochester Hills, Michigan, United States September 1, 2005

Energy Conversion Devices, Inc. (Nasdaq:ENER) announced today that, with the increasing acceptance of and demand for its Ovonic products as it continues its transition from a highly successful advanced technology research-oriented company to a more commercially focused manufacturing business, its Board of Directors has approved changes in its corporate organizational structure.

All production manufacturing and commercial operations will now report to James R. Metzger, executive vice president and chief operating officer. Stanford R. Ovshinsky, currently president and chief technology officer, will be named president and chief scientist and technologist. In this position, he will continue to lead the development of the full potential of the emerging "Hydrogen Economy," while focusing on further developing the science and technology of amorphous and disordered materials. Both Stan Ovshinsky and Jim Metzger continue to report to Robert C. Stempel, chairman and CEO of ECD Ovonics. The three executives comprise the office of the chairman, responsible for the Company's overall strategic direction.

To better serve the diverse photovoltaic market demands, the Board also approved the formation of two solar divisions.

The Ovonic Solar-Terrestrial Division which will report to Jim Metzger, will have responsibility for manufacturing and sales of building-integrated photovoltaic (BIPV) and PV roofing products. This division will also be responsible for the current 25/30MW solar module manufacturing plant in Auburn Hills, Michigan, as well as the recently announced second 25/30MW plant. The Terrestrial division serves a highly competitive and rapidly growing market, with multiple customers mostly from the building, roofing and construction industries. As chief operating officer, Jim Metzger will also be responsible for the Production Technology and Machine Division, hydrogen storage canister production, and the two joint ventures now in commercial production, Cobasys LLC, a 50-50 nickel metal hydride battery manufacturing joint venture between ECD Ovonics and Chevron Corporation, and Rare-Earth Ovonic, a joint venture with Inner Mongolia Baotou Steel Rare-Earth High Tech Co., Ltd.

The Ovonic Solar-Space and R&D Division will report to Stan Ovshinsky who continues to direct the overall advanced PV technology. Ovonic Solar-Space and R&D will have responsibility for government and military contracts, research and development, and the advanced ultra-lightweight PV for space and airship applications being developed under a contract with the U.S. Air Force. The Space and R&D division, due to its unique customers in the military and certain government agencies and industrial users, will be devoted to the development of new and advanced technology, such as meeting the rigorous demand of outer space and improved efficiency. As chairman of the Ovonyx joint venture, Stan has joint responsibility with Tyler Lowrey, president of Ovonyx. Ovshinsky also is responsible for the advanced solid hydrogen storage and cognitive computer development programs.
