Nowadays, pollution is getting worse and worse. It can be one of the biggest killers, affecting more than 100 million worldwide. You don’t want to die fast, right? Let’s save the world and be green with solar panel!
Pollution is one of the biggest issues that every nation faces right now. Every nation only competes to be the number one in economic development and sometimes ignore about environmental condition. The fact is every nation should attain sustainable development, which is balance between economy, environment, and social community.
Energy which is very important for economic development of nations is getting fewer. Every nation exploits energy in order to achieve rapid economic growth. Total energy needs in the world currently reach 10 Terra Watt and this number will increase until 30 Terra Watt in 2030. The increasing number of total energy needs collide with the sustainable concept that human needs to pay attention to. Solar panel as alternative energy source can solve this problem.
Solar panel is a panel designed to absorb the sun’s rays as a source of energy for generating electricity or heating. Solar energy is actually the most promising energy sources because it is unlimited and sustainable. The sun is expected to address future energy needs problem because most of energy sources are limited and not environmental friendly.
Solar panel work using p-n junction principle, which is the junction between p-type and n-type semiconductor. This semiconductor consists of bonds in which atoms are electrons as the basic constituent. N-type semiconductors have an excess of electrons (negative charge) while the p-type semiconductor has excess holes (positive charge) in the structure of the atom. The role of p-n junction is to form an electric field so that electrons (and holes) can be extracted by contact material to produce electricity. When the p-type semiconductor and n-type contacted, then the excess electrons will move from the n-type semiconductor to the p-type to form a positive pole on the n-type semiconductor, and conversely the negative pole to the p-type semiconductor. As a result of the flow of electrons and holes is to formed electric field which when the sun light on the composition of the p-n junction will push electrons move from the semiconductor toward the contact negative, which in turn is used as electricity, and vice versa hole moves toward the positive contact waited electrons come.
Solar panel consist of substrate/metal backing, semiconductor materiel, contacts metal/contact grid, antireflective coating, and encapsulation/cover glass. Substrate/metal backing is material that sustains all components of solar cells and it must have a good electrical conductivity. It can be made by metal material such as aluminum.
There’s a lots of advantage using solar panel, especially solar panel doesn’t cause any pollution and it’s free energy! You can be go green, save the world, and less money!
