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…
In a nutshell, solar panels generate electricity when photons (those particles of sunlight we discussed before) strike solar cells. The process is called the photovolatic effect. First discovered in 1839 by Edmond Becquerel, the photovoltaic effect is characteristic of certain materials (known as semiconductors) that allows them to generate an electrical current when …

Solar cell efficiency is typically expressed as a percentage and is calculated by dividing the electrical power output of the solar cell by the total solar power input. The electrical power output is determined by multiplying the voltage and current generated by the solar cell, while the solar power input is determined by the intensity of sunlight falling on the cell.
