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.
In a solar cell, the electrical current produced by the absorption of light is called the photocurrent. The quantum efficiency (QE) of a solar cell is defined as the number of electrons that contribute to the photocurrent divided by the number of photons with a given energy or wavelength that impinge on the solar cell.
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 QE of a solar cell is the fraction of the incident photons of a given wavelength (or energy) that are effectively used in the production of photocurrent.
As majority of our energy requirements are in the form of electricity, PV works on the principle of photovoltaic effect. The generation of thermal energy from solar can be realized using various solar reflecting collectors. Most of the technology works on the principle of reflection, radiation and convention or based on the thermosiphon effect.
Solar cells exploit the optoelectronic properties of semiconductors to produce the photovoltaic (PV) effect: the transformation of solar radiation energy (photons) into electrical energy. Note that the photovoltaic and photoelectric effects are related, but they are not the same.
