SOLAR ELEMENT

摘要

The invention concerns individual solar energy - photoelectric transformers or solar elements, producing electric energy from solar radiation. Under the influence of solar radiation the temperature of the solar element rises and its efficiency decreases. One of ways for cooling the element is to place it into circulating dielectric fluid, transporting the unnecessary heat to another heat consumer. The essence of the invention is: In order to increase the efficiency of a solar element in the cooling solution some pigment and/or paint is added, which evens the absorption curve of the solution. By choosing corresponding paint it is possible to reach practically perfect absorption of certain part of solar radiation spectrum into the dielectric solution. The paint has to be chosen so that the dielectric qualities of the solution are not lowered.
