Pv system 2 - Coursework ExampleSemi conductors are used in photovoltaic cells to provide voltage as a dissolving agent of light. The semiconductor absorbs the light thereby knocking electrons and letting them flow freely. This is a typical conversion of light to electricity at atomic level. The suns power originates from the unification of Hydrogen. The proton-proton reaction levys deuterons, which is the nucleus of an isotope of Hydrogen 2 that contains one neutron and one proton as a result of the ejection of the positron and an uncharged neutron form the deuteron forms the nucleus of a deuterium which is a heavy Hydrogen (Hedegus and Luque 79). Deuteron and proton combines to form triton or Helium 3 which is an isotope of Helium. Helium 4 can also be organize through the combination of two Helium 3 to form two protons and Helium 4 or a combination of triton and deuteron that produces energy, neutron and Helium 4. The meat energy yielded is 26.7MeV. This whitethorn be obtaine d through calculations based on the atomic mass energy of Helium 4 nucleus (Hedegus and Luque 79)Part of the radiation is alienated to the outer space through radiation as some is scattered by the atmospheric gases. Some of the heat that reaches the earths surface has an honest intensity termed as solar isolation and ranges between 0.6to 1.0kW/m2. This is mostly absorbed by plants as humans also harness the solar energy to produce electricity (Hedegus and Luque 48).In the production of electricity, the solar radiations are knockout by PV cells into a silicon wafer. This is usually done through optical systems concentration may also be done through luminescence (Gratzel 6848). Solar thermal power is an option of generating electricity through solar energy. Solar power is concentrated in solar power towers and focused into a fluid that bares a fluid. The temperature increases and it turns turbines thereby producing electricity.There are commercially available PV
