Energy Conversion Devices, Inc. to Host a Media Briefing Tuesday, June 6

  What:   Energy Conversion Devices, Inc. (ECD Ovonics)
will
          host a media briefing to announce a fundamentally new device with
          potential to open a whole new field of semiconducting control
          devices.  Stanford R. Ovshinsky will discuss the Ovonic Quantum
          Control, a unique proprietary all thin-film control device based
          on his invention.  The Ovonic Quantum Control device is based on
          new physics and has multifunctionality beyond that of transistors.
          Its nanostructure size, great speed and very high current carrying
          capacity, together with unusual modulation including gain, provide
          advantages over transistors.

  Who:    Stanford R. Ovshinsky, President, Chief Scientist and Technologist
          Robert C. Stempel, Chairman and CEO

  When:   Tuesday, June 6, 2006 at 10:30 a.m. (EDT)

  Where:  Energy Conversion Devices, Inc.
          2956 Waterview Drive
          Rochester Hills, MI 48309
