At present, there are two main ways to use solar energy: photothermal conversion and photoelectric conversion. A flat-plate solar collector is a light-to-heat conversion device that absorbs solar radiation energy and transfers heat to a working fluid. It refers to a non-concentrating heat collector in which the heat absorber is basically flat. The heat absorber refers to the device in the collector that absorbs solar radiation energy and transfers heat to the heat transfer medium.
