1. A heat collector comprising two opposite surfaces and one or more surrounding sides; wherein a matrix of the heat collector is made from a thermally conductive material; an adiabatic dope selected from a group consisting of polymers, ceramics, silicon oxides, and asbestos is mixed within the matrix; and a relative concentration distribution of said adiabatic dope increases from one of the opposite surfaces to the other opposite surface, and decreases from the surrounding sides to the center of the heat collector.
