WebFor the transfer of heat from the sun to the earth, the energy emitted from the sun has to travel through the vacuum. This is possible by the radiating electromagnetic wave by the sun which can easily travel in a vacuum. This mode of heat transfer is known as Radiation. To know, why it takes place only by radiation, we should know all possible ... WebMoreover, the use of these diffuse reflectors can offset the negative effect of the optical losses in the case of glazed PV-T collectors, achieving higher electrical and thermal efficiency. Thermal efficiencies of up to 80% and 75% for water and air extraction modes respectively have been reported [ 71, 73 ].
