Abstract
There is disclosed a new and improved material and device for improved selective absorption of light energy for use in photothermal applications and a method and apparatus for manufacturing same. The device includes a layer of thermal infrared radiation reflecting material containing a transition metal or stainless steel. A solar radiation absorbing layer is deposited over the infrared reflecting layer. This layer comprises either amorphous boron or an amorphous alloy of boron and silicon, boron and germanium or boron and molybdenum. Finally, a solar radiation antireflecting material layer is deposited over the solar radiation absorbing layer. This layer comprises an amorphous alloy of nitrogen and either silicon or boron.
