Concentrated Solar Power System Receiver

A solar energy receiver forming an inlet aperture disposed along a side thereof, the solar energy receiver further comprising:

• a container structure adapted to contain a molten salt pond with an exposed surface, the container structure defining an opening that permits passage of solar radiation directly from the inlet aperture therethrough to impinge on at least one of:
• the exposed surface and penetrate into the pond;
• and
• an underside of the any cover prior to impinging on the exposed surface and penetrating into the pond;
• and
• a vertically movable divider plate disposed horizontally in the container structure so as to divide the container structure into an upper portion and a lower portion, the divider plate forming an annular gap space that allows flow of the molten salt between the upper and lower portions of the container,
• wherein the exposed surface is exposed across an entirety of the opening of the container structure and the exposed surface is exposed to ambient environment.
