The photovoltaic effect is based on the creation of an electric current in a material, usually a semiconductor, upon light irradiation. When sunlight irradiates the solar cell, some photons are absorbed and excite the electrons, or other charge carriers, in the solar cell.
The performance and efficiency of solar PV vary according to types of cells. The mono-crystalline solar cells feature high energy efficiency, but it has a complex manufacturing process. The multi-crystalline solar cells are cost-effective but suffer from low efficiency in comparison to mono-crystalline solar cells.
Above 90% of the current photovoltaic production is based on silicon (Si) solar cells. However, typical commercial solar cells have an average efficiency of around 15%. That is, about one-sixth of the sunlight irradiating the Si solar cells is transformed into electricity.
Current-voltage characteristics and power as a function of solar cell voltage. The most important parameters for users of photovoltaic systems include: maximum power, fill factor and photovoltaic conversion efficiency (photovoltaic cell efficiency) [24–28].
PV cell efficiency increases with solar irradiance, as the greater number of photons associated with higher solar irradiance creates more electron–hole pairs and consequently more current in the photovoltaic cell.
In the international renewable energy production frame, photovoltaics (PV) is a well-established technology, which aims to produce electric energy from the sun radiation . Above 90% of the current photovoltaic production is based on silicon (Si) solar cells. However, typical commercial solar cells have an average efficiency of around 15%.
