Abstract: A solar receiver is provided, comprising a receiver housing, a window positioned within the housing and configured to allow solar radiation to penetrate therethrough, a receiver volume defined between the receiver housing and the window, a fluid inlet operative to allow a fluid to flow therethrough into the receiver volume, a fluid outlet operative to allow the fluid to flow therethrough out of the receiver volume, and a solar radiation absorber disposed within the receiver volume. The solar radiation absorber surrounds at least a portion of the window so as to be heated by the solar radiation penetrating therethrough, and is configured for heating the fluid within the receiver volume. The solar radiation absoτber defines therein a helical fluid channel between the fluid inlet and outlet for flow of the fluid therethrough.
