Solar Cells. Silicon photovoltaic cells are typically thought of as voltage supplies, but they are also useful as sensitive detectors of light and near infrared. Solar cells are silicon wafers which are doped to produce a p-n junction monly used "cells" are produced as wafers of diameter about 8 cm and 3 mm thickness which are cut from a crystalline silicon rod.
Solar cells started in 1876 with William Grylls Adams along with an undergraduate student of his. A French scientist, by the name of Edmond Becquerel, first discovered the photovoltaic effect in the summer of 1839. [7] He theorized that certain elements on the periodic table, such as silicon, reacted to the exposure of sunlight in very unusual ways.
Solar cells are commonly recognized as one of the most promising devices that can be utilized to produce energy from renewable sources. As a result of their low production costs, little material consumption, and projected increasing trajectory in terms of efficiency, thin-film solar cells have emerged as the technology of choice in the solar …
