Abstract:
     This invention is applicable to solar energy utilization device such as solar greenhouse, solar house, solar drying house, and solar pit, etc., as light-heat energy trans-formation material of non-metal heat absorbing surface. The material is basically composed of Z parts, organic and inorganic, containing mainly carbon black as heat absorber, this material absorbs 95-96% of solar energy. When properly bound to the bottom layer, it can be used for long period in moist conditions and at a temperature above 80 deg.C, and it can be exposed to strong sun light for more than 5 years without any decaying of its properties. It is easily built, and will not bring about any pollution to environment.
