Environmental and Market Driving Forces for Solar Cells • Solar cells are much more environmental friendly than the major energy sources we use currently. • Solar cell reached 2.8 GW power in 2007 (vs. 1.8 GW in 2006) • World''s market for solar cells grew 62% in 2007 (50% in 2006). Revenue reached $17.2 billion.
Solar cell is a device or a structure that converts the solar energy i.e. the energy obtained from the sun, directly into the electrical energy. The basic principle behind the function of solar cell is based on photovoltaic effect. Solar cell is also termed as photo galvanic cell. The electricity supplied by the solar cell is…
FIGURE 3 A PV cell with (a) a mono-crystalline (m-c) and (b) poly-crystalline (p-c) structure. Photovoltaic (PV) Cell Components. The basic structure of a PV cell can be broken down and modeled as basic electrical components. Figure 4 shows the semiconductor p–n junction and the various components that make up a PV cell.

Using the same logic, a team of MIT researchers have stacked a bunch of photovoltaic solar cells together to produce up to 20 times the power output of conventional solar power installations.
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron …
