solar cell
A commonly used solar cell structure. In many such cells, the absorber layer and the back junction layer are both made of the same material.
A typical 10-centimetre by 10-centimetre solar cell generates approximately two watts of electrical power. This output represents about 15 to 20 percent of the energy from the light incident on the cell's surface. Because a single cell produces a relatively small amount of power, they are commonly combined in series or parallel configurations to meet specific voltage and current requirements for practical applications.12
