Alexander Edmond Becquerel opened the photovoltaic effect in far 1839. In 44 years Charles Fritts managed to construct the first module that could use the solar energy. And selenium coated with thin layer of gold served as the basis then. Scientists have found that this combination of elements makes it possible, albeit marginally (about 1%), to convert solar energy into electricity.

Every day brings many pleasant and not very pleasant surprises to the evolution of humanity. We must pay with something for every progress peak` conquest. All of us know from school the truth about the limitless nature of human needs. Their implementation requires an incredible amount of resources, which are not infinite.

The question how to make the sun work for us, how to make the process of the sun’s rays energy extracting simple, cost effective and cheap?

The year 1883 is considered to be the year of the solar energy era birth. However, not all people think so. There is a perception in the scientific world that the “father” of the solar energy epoch is the great Albert Einstein. In 1921, Einstein was awarded with the Nobel Prize. Many people believe that a great scholar of 20th century was awarded due to his rationale formulated theory of relativity, but it is not true. It turns out that the physicist got the prize for an explanation of the photoemission laws.

Over a hundred years a man could see a development of the industry experienced sharp rises of private and public institutions investment that were stimulated with scientists. But the history knows the bitter falls, that prompted the society to forget about “solar technology” for years.
