Materials Engineering in Photovoltaic cells In today’s world when we think about energy sources, there are 2 classifications they can be split into: renewable and non-renewable sources of energy. Fossil fuels are the backbone for most of the energy we use today. We need this fuel for almost all of our daily routine, from lighting a fire to running heavy machinery, but with increase in population there has been an increasing demand of such energy. Fuels like these tend to give massive amount of energy but also affect the environment by producing harmful gases and residue. With the depletion of the fossil fuels such as coal and petroleum we needed to switch to alternate form of energy which and there has been an ever greater need for a cleaner and renewable form of energy. Humans have tried to find many alternative (and renewable) forms of energy such as wind and water but not at a very large scale. With an abundance of solar energy available to harvest, it is one of the most widely cultivated renewable forms of energy. Solar cells or photovoltaic are the primary devices that are able to harvest the sun’s energy in a form that can be used every day. Semiconductors are one of the more widely used materials in the solar cells industry; however other materials such as organic photovoltaic, solution-processed solar cells and dye-sensitized solar cells are also used in the market. To understand the basic principle behind the working of a solar cell, we have to look down into the
