Abstract

A selectively absorbent layer for solar collectors, comprising a mixture of chromium oxides resulting from thermal decomposition of chromium hexacarbonyl or substituted chromium carbonyl. The absorbent layer is deposited from a process gas containing the carbonyl gaseous phase, oxygen, and inert carrier gas. An intermediate reflective layer is provided between the absorbent layer and the substrate.
