Solar Energy Discovery and its Father

Solar Energy has been used by different and various ancient civilizations since the humans started thinking.Some ancient buildings are constructed with the idea to focus the sunlight inside the living area of a building,Providing an available path for entering sunlight is not only the reason but also the flow of air from downward to upwards by removing the building heat automatically."Our Forefathers are that much brilliant"However ,the person who came up with an idea to harness the solar power to create electrical energy was Alexandre Edmond Becquerel.This is the first move in modern world to create electricity from
sunlight.

Alexandre Edmond Becquerel built the world’s first photovoltaic panel at the young age of 19 and that was in the year of 1839

He was a French Scientist,He was born on March 24th 1820 in paris,France.His Father Antoine Cesar Becquerel,another renowned french scientist,He continued his fathers work and research.His main area of interests are "Electricity","Magnetism","Optics","Solar Spectrum",He joined as a professor at Agronomic Institute in Versailles,1849.

Invention of Phosphoroscope:

He had an active interest in the study of light,He started research on Phosphorescence,photochemical effects,electric light and solar radiation.He was the first to research these topics extensively.He invented Phosphoroscope,A phosphoroscope is piece of experimental equipment devised to measure how long it takes a phosphorescent material to stop glowing after it has been excited.

It consists of two rotating disks with holes in them. The holes are placed on each disk at equal angled radial lines and a given distance from the centre but they do not align with each other. A sample of phosphorescent material is placed in between the two disks. Light coming in through a hole in one of the discs excites the phosphorescent material which then emits light for a short amount of time. The disks are then rotated and by changing their speed the length of time the material glows can be determined.
