ABSTRACT:
A solar collector for absorbing solar energy and for conversation thereof into thermal energy includes an aluminum foil. One side only of the aluminum foil is blackened to an extent such that it will absorb solar energy, preferably to an extent approximating a black body. The blackening is achieved by subjecting the one surface of the aluminum foil to an electrochemical surface etching treatment.
