Edmond Becquerel, a physicist, at the age of 19 was the first to demonstrate the effect. He observed that when light hit silicon it generated electricity. Since then solar energy from photovoltaics (PV) has emerged as one of the most used sources of power worldwide. It powers applications ranging from household appliances and lighting to spacecraft and satellites orbiting our planet.

Solar cells serve as the components in any energy system. These cells are composed of semiconductor materials like silicon, the material utilised in the microelectronics industry. Through treatment they establish a field with a positive side and a negative side. When sunlight strikes a cell it energises the semiconductor wafer by dislodging electrons from atoms within the silicon material. Consequently an electric current is converted into electricity by the internal circuitry within the cell. For Solar Panels, go to GSM who are providers of Solar Panels
Modern PV technology employs junction cells based on monocrystalline or polycrystalline silicon. These cells selectively absorb portions of sunlights spectrum that possess energy to surpass the band gap present in semiconductors. Meaning only photons with adequate energy levels can liberate electrons, for an electric current to flow.
Researchers are currently engaged in the development of solar cells with the potential to achieve efficiencies surpassing 50%. Such advancements would result in a conversion of solar energy into electricity. To optimise photovoltaic (PV) production, it is recommended to position panels ensuring they receive full sunlight and are tilted at an angle that closely aligns with the local latitude. Additionally certain scenarios may require the inclusion of blocking or bypass diodes to address shading within an array, which has the potential to significantly diminish output.
