An improved solar energy absorber is provided in which the absorber surface is prepared from a multiplicity of fibers having free ends which are tapered and coated with a low emissivity material. The fibers are straight, aligned in a parallel relationship and have diameters of from about 4 to 100 micrometers. The fibers are spaced together very tightly so that the distance between adjacent fibers is from about 1 to 10 micrometers. The fiber surface presents an improved solar trap for absorbing solar energy.
