The Cost of Solar Cells to Harvest Energy Essay -- Power Environment R

solar Cells - nada of the Futuresolar booths have been around since 1883, when the first solar cell was created. Even though they have been around for so long, many wad still wonder why they have not been implemented into wide-scale practise already. Solar cells today are highly efficient and earth-closet pass on enough energy to power many cities today. But what is holding them second from being used in developing countries that have a find out to base their society around them, or in already true countries? Simply put- the cost.Before I go in to detail well-nigh usage and implementation of solar cells, let me explain just how they work. Solar cells, also known as photovoltaic cells (Photo= light Voltaic=electricity) pose photons, convert them into electrons, and use these electrons to transfer energy to whatever you want to power. To do this, solar cells are made with a material called a semiconductor, which, for solar cells is almost always silicon. When light hits this material, it causes electrons to break loose and accrue throughout the material. By placing metal plates on the solar cell, we can capture this flow of electrons, otherwise known as current. Using the equation Power= Volts * Current, you can calculate the voltage output of a cell, which, using silicon, is about 1.1 volts- a 25% or so efficiency.There are currently trio types of solar cells- first generation, second generation, and third generation, where each generation shows to administer a certain problem with solar cells. First generation cells propose to make as many cells as possible, second generation aim to make highly effective solar panels, and third generation cells refine to create the most costefficient solar panels.
