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.
The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device.
Individual solar cell devices are often the electrical building blocks of photovoltaic modules, known colloquially as "solar panels". Almost all commercial PV cells consist of crystalline silicon, with a market share of 95%. Cadmium telluride thin-film solar cells account for the remainder.
The actual current densities of the most efficient silicon solar cells reach values higher than 42 mA/cm 2, remarkably close to the theoretical maximum. In a solar cell, the electrical current produced by the absorption of light is called the photocurrent.
For most solar cell measurement, the spectrum is standardised to the AM1.5 spectrum; the collection probability of the solar cell, which depends chiefly on the surface passivation and the minority carrier lifetime in the base.
The working principle of solar cells is based on the photovoltaic effect. The PV effect can be divided into three essential procedures [18, 19, 20]. Absorption of photons in a p-n junction electronic semiconductor to generate the charge carriers (electron-hole pairs).
