Clarification on What Is Solar Technology

he idea of using sunlight as an energy source is not so new.
In 1839, for the first time, this effect was discovered by Alexandre Edmond Becquerel.
He found in some experiments with electrolytic cells that current flows are little more light than in the dark.
However, it will still take some time before this discovery could be used in practice. 1883 the first forerunner of today’s solar cells was developed, it was built by Charles Fritts.
1921 managed to Albert Einstein, the theoretical explanation of this effect, for which he received the Nobel Prize in Physics.
Two years later, the effect could also be confirmed in an experiment, and so he also received a Nobel Prize.
