Solar Energy Name Institution Solar Energy The sun provides an implausible amount of energy, which plants change into chemical energy to manufacture their own food. The sun is therefore, the source of energy to most of the renewable power harnessed on earth…
A distinctive mesophyl cell contains 30 to 40 chloroplasts. In plants, a strike of sunlight excites one electron in the chlorophyll molecule to bump it up into a higher level of energy. Before it drops back to the initial state, life is enhanced between these two processes and the electron is drawn back within its machinery thus utilizing the energy (Maders, 2010). According to Maders (2010), solar cells are simple in that they are made from specific sources that are neither electricity conductors such as copper wire nor insulators such as plastics. When they are exposed to the sun, they absorb photons which are light particles and other types of electromagnetic radiations. These materials are called semi-conductors as they allow electric currents to be produced. Photons contain several energy amounts depending on the varying wavelengths of the solar range. This level of energy determines what happens immediately the photons hit a photovoltaic cell the place where they pass, get absorbed or reflected. Some of the photons absorbed are used to generate heat, others electricity while some do not reach the external circuit. Similarities between Photosynthesis and semiconductors Photosynthesis and semi-conductors are the same in the sense that they aim to trap solar energy. For instance, plants utilize photosynthesis to trap solar energy to manufacture food. ...
