Solar energy converters convert solar radiation into usable heat energy by means of a reflector which collects and focuses the solar radiation onto an absorber provided with an internal chamber through which a heat exchange fluid may be passed. As the absorber is heated by radiation focussed thereon the heat may be extracted into the fluid. To minimize the volume of the internal chamber and thus increase the efficiency and sensitivity of the heat transfer, the absorber is formed with curved walls to define an internal chamber having a crescent-shaped cross-section.
