After 40 years of research, scientists have found a flaw that reduces the efficiency of solar panels by 2%

Important. At first sight, that 2% - this is just ridiculous and minuscule, but in fact if you look at the broader issues, in a planetary scale, increasing the efficiency of the panels by only 2% will completely stop a few average NPP power.

Alternative energy grows and the solar panels are the leader in the development of this industry, and on how they will be effective depends on the amount of electricity generated.

Above the constant increase efficiency Panels operate many groups of scientists around the world, and that one of them managed to find the cause of the so-called light degradation (LID) Of solar panels in the first hours of their work.

In order to find this defect was produced silicon analysis using experimental apparatus Deep-level transient spectroscopy (DLTS), The use of which has revealed weaknesses in the panels.

Thus with this apparatus it has been found that in the process of converting sunlight into electricity of the electrons fall into the so-called

"Structural traps". This process reduces the efficiency of the panel by about 2%, and leads to degradation of the material.

It was found that the panels used where a high-quality silicon, this defect is observed to a lesser extent.

The same researchers as a result of experiments it was possible to return the panel to its original state. To this end, the material has been warmed up in complete darkness up to 200 degrees Celsius and subjected to "annealing" quite a long time.

After such a "roasting" the panel has restored their original properties. Ucheny a process called annealing, and the panel that has passed this procedure - the solar panel in the annealed condition.

Most strongly such a defect occurs in the first few hours of the solar panel (until it warmed up by the sun). So now the scientists and engineers the task to eliminate this phenomenon in the production of new panels.

All of its research and calculations of researchers published in the journal Journal Of Applied Physics.
