All the aspects presented in this chapter will be discussed in greater detail in the following chapters. The working principle of solar cells is based on the photovoltaic effect, i.e. the generation of a potential difference at the junction of two different materials in response to electromag-netic radiation.
The second chapter contains the review of semiconductors and their properties, and gives a comparison among semiconductors and insulators in terms of their energy band structures. In Chapter 3, the structures and types of solar cells are summarized, and general aspects of the working principles of solar cells are explained.
1.5 watts of power at 0.5 volts DC and 3 amps under full sunlight (1000 ). The power output of the cell is directly propo rtional to the inten sity of the su nlight. It means for example, if the intensity of the sunlight is halved the power will also be halved.
The power can be extracted from the device in a region shown in the fourth quadrant. The solar cell is the basic building block of solar photovoltaics. When charged by the sun, this basic unit generates a dc photovoltage of 0.5 to 1.0V and, in short circuit, a photocurrent of some tens of mA/cm2.
