Since the sun is generally the source of radiation, they are often called solar cells. Individual PV cells serve as the building blocks for modules, which in turn serve as the building blocks for arrays and complete PV systems (see Figure 1). Figure 1. The basic building blocks for PV systems include cells, modules, and arrays.

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…
