A solar energy conversion system is provided which includes a black body receiver for transferring energy from focused solar radiation to a circulating gas. The receiver includes a honeycomb heat exchanger located within a chamber sealed with impingement cooled windows, the outermost one of which acts as a one way trap or diode to prevent energy radiated by the heated honeycomb from escaping to the atmosphere. The heat exchanger is formed with a number of tubes which are oriented to be illuminated "end on" for minimizing retroreflection of the incoming energy. Because of the "end on" orientation, a large majority of the incoming energy impinges on the internal walls of the tubes and is internally reflected until it is absorbed. Cool gas, which may be air, is introduced into the receiver under pressure such that the gas passes through the tubes of the heat exchanger where it is heated to temperatures that are typically in the vicinity of 1700 DEG F. The heated gas is then extracted from the receiver downstream of the tubes.
