oxidation of copper and aluminum composite flat plate solar collectors

  • R.

    The efficiency of solar photothermal collectors is increased by the use of a spectrally selective absorber which has a high absorptivity over the range of the solar spectrum and low emissivity in the infrared. Such a collector absorbs much of the incident solar energy but loses little energy by reradiation. Composite .
