Solar power is one of the three main energy sources associated with alternative energy amongst hydro and wind. In today’s world, the need for this alternative energy is at an all-time high as fossil fuels and other conventional sources of energy are beginning to damage this planet’s ecosystem at an alarming rate. Solar energy, although not completely pollution-free, is an inexhaustible fuel source. Every hour energy from the sun is sent into Earth’s atmosphere and within this hour, there is enough energy provided and harnessed to fuel the entire planet for one year. 1Today, this solar power is utilized in a manner that only allows it to produce less than 1/10th of 1% of Earth’s total demand for fuel and/or energy. 2This planet receives approx. 174 petawatts (PW) on incoming solar radiation in the upper atmosphere, and while 33PW of this radiation is absorbed or reflected back into space by the atmosphere, clouds and the earth’s surface, the remaining 89 PW is an attainable energy source that is currently almost completely absorbed by land and oceans. Although not completely utilized, solar radiation is still harnessed through ever-changing technologies such as solar heating, solar thermal energy, solar architecture and artificial photosynthesis.

When the sun’s light hits an object, the energy from this radiation is transformed into heat. Using this same ideal when using certain materials, the radiation can be transformed into an electrical current instead. This concept is…
