The Working Principle of a Solar Cell

The Working Principle of a Solar Cell In this chapter we present a very simple model of a solar cell. Many notions presented in this chapter will be new but nonetheless the general idea of how a solar cell works should be clear. All the aspects presented in this chapter will be discussed in greater detail in the following chapters.

A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light. Individual solar cell devices are often the electrical building blocks of photovoltaic modules, kn…
