Traditional Solar Cells Advantage And Applications

Currently solar power is beginning to expand horizontally throughout communities. This growth is creating a demand that is beginning to reduce the expense of purchasing and installing solar panels. The concept is catching on and the technology is improving as the demand increases.

Commonly, renewable energy is defined as energy which is able to be captured from existing natural resources that are replenished rapidly, such as flowing water, sunshine, wind, geothermal heat flows and ocean [2]. Renewable energy technologies are required to provide technologies to use one or several renewable energy resources. There are some different types of renewable energy technologies, which include solar energy, bioenergy, hydropower, wind energy, geothermal energy and tidal energy. This thesis project will focus on the solar photovoltaic which is currently one of types of solar energy technologies, and this technology using photovoltaic cells to converts sunlight directly into electricity.Solar photovoltaic system can generate electricity from sunlight through using PV modules, and the system can be integrated into building designs, installed on rooftops, or large scale power plant. With the development of photovoltaic technologies, solar photovoltaic capacity has been increased from 3.7 GW (2004) to 177GW (2014) [3]. Figure 2 shows this change from 2004 to 2014, there is a big trend of increase in these years. The increase of PV capacity can reduce the carbon emission and provides more job opportunities. It also helps to reduce air pollution and make a friendly environment for living. One of the common PV system is

Recently, the price of unrenewable energy resource such as oil, coral and natural gas is increasing by time because of rare and more and more usage for individual and industries. Solar panels which use energy from Sun are considered as renewable energy through the form of solar radiation, UV. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they

In the last decades energy consumption has come to a time where people started noticing the climate changes and the effect of fossil fuel energy for not only being environmentally destructive, but also causing Global warming (the warming that occurs as a result of increase emissions of greenhouse gases) has become a very big issue worldwide. The fossil fuels (Oil, Coal, and Natural Gas) which is the main sources of the world’s energy sources, is also one of the main causes of the climate change. In addition with some human activities (e.g. through burning fossil fuels), they have contributed immensely to the global warming, which has also affected the climate conditions in the world. The affect of these changes has prompted some people to propose alternative energy like solar panels. According to Abby Gruen, after realizing the issues, the engineers at Bell Laboratories come up with the first useful photovoltaic cell, an alternative to fossil fuel energy but less harmful for the environment and the pocket. Solar panel which uses renewable energy like the sun to light homes heat and produces electricity. Unlike fossil fuel, solar panels is less harmful for the environment. Since it creation few decades ego, just recently solar panel started getting popular in homes in the United States and around the world. When it was invented people were not interested about it, because of the high installation price, however the price has changed dramatically since then. Even though

Solar cell or photovoltaic (PV) systems usually transformed energy from the sun in to electric current. It can be measured in terms of ‘‘conversion efficiency’’, the proportion of solar energy transformed to electricity. (Henderson, Conkling, & Roberts, 2007) Sunpower primarily focused on the production of solar cell. But by moving in to wafer manufacturing it soon incorporated in to manufacturing of solar power module units. In general Sunpower manufacturing process needed approximately two times as many steps as the usual solar manufacturing process need and many of these steps were distinctive to Sunpower. Sunpower has nearly 15 -20 established cell manufactures, a handful of silicon – based cell manufacturing upstarts and a number of thin film solar companies offering potentially unsettling technologies.

Sure, solar cells are a tremendously active research area and there are improvements being made every day. But even taking this into account, it is not conceivable that solar cells, even when pushed to the limit, will replace conventional sources of energy in even the medium term. Compare the ambitious 20,000 MW goal for 2020 with the overall target of 62,500 MW for 2012 and the scales are clear. While solar energy could prove to be significant locally to states like Gujarat and Rajasthan, on a national level, solar energy cannot be our main source of energy for the next 20 years or so.

increased due to the limited amount of available oil. Global warming is considered as a byproduct

The process of creating the Solar panel is not an easy process. Solar panels are made up of mostly different types of silicon and glass-like substances. The process of making them and installing them is costly, but after that they are done, they are fine. A photovoltaic cell is a cell that converts solar energy into electrical energy(

Wind energy is another common renewable energy source. Wind turbines are used to convert the wind energy or

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

The limited resources of non-renewable energy and the fluctuation of fuel price have forced the world to find clean and economical natural energy resources by means of renewable energy. Solar energy is a sustainable alternative option that can be utilized in various ways and can be used in many applications.

Green technology is most utilized today in the quest for alternative energy. Solar energy, wind turbines, and using the oceans energy are in the lead for making a softer imprint on the planets environment and its resources. Solar panels use the heat from the sun to convert into useable electricity. That energy can either be stored in batteries or returned to the local energy provider if still connected to them. The idea of this is to utilize the local grid as a bank to receive credit for the energy you provide and pull it out when needed with little to no charge. The panels that provide this are fast becoming more cost effective, easier to handle, and readily available to the average consumer. Robbins (2009) demonstrates an example of these promising ‘thin film’ solar cells as seen in Figure 2 of this paper.

Solar cells are also known as photovoltaic cells, which suggest that light energy is being converted to electrical energy. Most photovoltaic cells consist of silicon in its crystalline structure. In that structure, each silicon atom has four valence electrons, and each one bonds to an adjacent electron. Silicon then is a poor conductor since electrons cannot move freely through the substance, but the addition of impurities such as phosphorus, which is called doping, to the silicon crystalline structure provide extra electrons called free carriers that can be knocked off the atom via light energy.6 The section of the photovoltaic cell that is doped with phosphorus is called the N-type because it has numerous negatively charged electrons flowing and creating a current. On the other hand, the section of the photovoltaic cell that is doped with boron is called the P-type because boron only has three valence electrons.7 When the N-type and
