Technical Background The Department of Energy's Solar Thermal Technology Program was started in 1975 and was concerned mainly with the use of concentrated solar energy to produce electricity. In solar thermal systems, solar radiation is concentrated win mirrors onto a receiver, where it is absorbed as heat.

The goal of the present work was to determine whether special advantages might result from using concentrated solar photons for photochemical, photoelectrochemical, and thermal processes and to assess the state of the art of potenha1 applications, such as water and waste treaunent. Other possible applications of solar photons, such as materials processing and solar pumping of lasers, were also considered.

Furthermore, as part of He committee's mandate to review relevant international research and development activities In solar chemistry and technology, it undertook two efforts. Ibe committee chairman, Allen Bard, attended the International Energy Agency Symposium on Solar High-Temperature Technologies, in Davos, Switzerland, on August 27-31, 1990, and exchanged perspectives with various European experts at the symposium.
