Abstract
A solar light (heat) absorption material is provided which has an excellent solar light (heat) absorbing ability and a simple structure, and may be usable as a low-cost and high-performance heat absorption/accumulation material, the inventive material being usable also as a solar light (heat) absorption/control building component that allows easy change of its solar light (heat) absorption/control ability. The material comprises particles dispersed into a liquid medium having a specific heat ranging from 0.4 to 1.4 cal/g/° C. and a melting point of 5° C. or lower. The dispersed particles have L*value of 30 or less as determined by the CIE-Lab color system (light source D65).
