Solar Cells

Paper Summary:

This paper defines what solar cells are, how they are created and the technological history behind their development. It provides scientific theories to support this information and explains the uses of solar cells in today's technology.

From the Paper:

"A solar cell is any device that directly converts the energy in light into electrical energy through the process of photovoltaics. Unlike batteries or fuel cells, solar cells do not utilize chemical reactions to produce electric power, and, unlike electric generators, they do not have any moving parts. Solar cells are also called solar batteries and, as the term solar implies, they are in most cases designed for converting sunlight into electrical energy.
"In the basic structure of a typical solar cell, light enters the device through a layer of material called the antireflection layer. The function of this layer is to trap the light falling on the solar cell and to promote the transmission of this light into the energy-conversion layers below. Such materials as silicon oxides or titanium dioxide are employed as the antireflection layer in solar cells."
