Solar Energy

more popular all over the world. There are primarily two technologies for converting solar energy to electricity. Solar thermal-electric power plants use mirrors to gather solar radiation and focus it on a small area to produce high temperatures. Photovoltaic cells, when struck by light, release electrons that combine into modules and later arrays. Solar energy is very abundant. The surface of the earth receives 120,000 terawatts of solar radiation (sunlight) – 20,000 times more power than what is needed...

Solar Energy: the Energy of the Future

last way to convert solar energy is the use of solar cells or photovoltaic cells. Photovoltaic cells are made up of at least two semi-conductor Li, 3 layers, one layer being positively charged, and the other being negatively charged. "When a photovoltaic cell is exposed to sunlight, photons from the sunlight are reflected, pass through, or absorbed by the solar cell." (solarenergy, 1) When enough photons are absorbed by the photovoltaic cell, electrons are freed from the negatively charged semiconductor...

Sources of energy

development. Solar[edit] Main articles: Solar power and Artificial photosynthesis The primary obstacle that is preventing the large scale implementation of solar powered energy generation is the inefficiency of current solar technology. Currently, photovoltaic (PV) panels only have the ability to convert around 16% of the sunlight that hits them into electricity.[95] At this rate, many experts believe that solar energy is not efficient enough to be economically sustainable given the cost to produce the...

Physical Principles of Solar Energy

collector. The overall idea here is to heat water using the suns energy so that people may have hot water when showering, washing dishes, cleaning clothes, and more (How Solar Energy Works). The last concept that will be discussed is known as photovoltaic, which is another way of generating electricity by collecting the suns energy. However, water is not involved with this method. Instead, a semi-conductor material is used and when sunlight comes in contact with the outside of the PV panel, electricity...
