Generation of Electricity - Assignment ExampleHowever, the PVs may also be ustilised in the production of alternating current when appropriate appliances atomic number 18 utilised.According to Knier (2002), photovoltaics uses the atomic level to convert white directlt into the contemporaries of electrical energy. These involve using materials that can absorb light photons and later release electrons, such materials are said to have photoelectric effect. The capturing of the electrons produced by the photoelectric effects helps in the generation of electricity.According to the plat above, rays from the sun are tapped by the photovoltaic cells. A common photovoltaic cell is a te cell that consist of N-type and P-type silicon. Thses silicon are located at the top most part of the material. The generation of electric field takes place at the upper part of the cells where the two silicons are situated. They comes into contact with the articulation of the materials (referred to as P- N junction) (McNichol, 2006 Bazilian et al., 2013). The sunlight strikes the electric filed to induce motion of the electron that results in the flow of current. The size of the fall out area of the PV cell determines the amount of electricity generated. The intensity of the rays from the sun also affects the amount of current generated. The larger the size of PV cells and the more intense the rays, the higher the amount of electrons generated hence increased electric supply. For instance a cell with an area of 150 cm2 will generate 2 watts power.When a solar panel is exposed in the sunlight as shown in the diagram below, it will generate electricity that can be measured. The voltage produced is around 100volts on a single day when there is best sunshine. This can be stored on batteries arranged in series as shown in the diagram below. The results of such a strategy depends on the size of the panel and the amount of sunshine ( Knier, 2002 Wolfgang, 2013).Primary batteries are gi mcrack because
