Basic principle of photo thermal solar energy conversion
Photothermal conversion of solar energy, to produce hot fluid or hot air, takes place in solar collectors. Efficient conversion requires that a solar-absorbing surface is in thermal contact with the fluid or gas, and that thermal losses to the environment are minimized.
