Photovoltaic Materials Essay

In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these. As a world, we are dependant on dwindling fossil fuel supplies and take for granted electricity, oil, and gas. There are four completely renewable sources of energy around us that should be used and developed, they are: wind, growing plants, flowing water, and the sun. These sources of energy are the ones we should be tapping, because they are reliable and renewable. Harnessing the suns energy is the most certain and ultimate energy source. Looking at a brief history and some facts about solar energy, a glimpse of the future can be seen, a future not dependant on

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

It is interesting to note that when man was created, his needs were all around him. Some were obvious such as food and water, but other needs needed discovery like solar energy. Solar energy is the most ancient kind of energy known to man, however, man started researching it in the early 19th century.

Solar energy is constantly improving, whether that be financially or more efficiently. As a result, solar panels, a large focus in solar technology, are becoming less expensive. The price of producing panels has decreased dramatically. However, a popular belief is that solar energy is more expensive than fossil fuels. A recent Arabia

In addition, solar energy operational costs are manageable. It is free from monthly charges compared to conventional sources of energy. Solar energy does not require raw materials such as oil and coal, and once the panels are built, there will be no monthly charges. In addition, the prices of fossil fuels are increasing day by day, and this means conventional energy will be very expensive. Solar energy will remain the most capable world’s future power supply because, it is cost effective once the plants are built, and there will be no transport costs like for conventional energy sources. Therefore, solar energy is cost-effective, and will help in future energy supply, as the maintenance cost is affordable, as long as they are installed properly, and are working efficiently ( Hans, 2012). Furthermore, with the improvement and advancement of technology, it will increase its efficiency, and cost of production thus, making it more cost effective and the world’s best

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.

As world population continues to rise and economic development drives energy consumption upward, the necessity of energy diversification will intensify. Obvious concerns for fossil fuels, such as their inherent finitude and the pollution costs, only further accentuate the need for adoption of non-fossil fuel energy sources. In the renewable energy market solar energy is an increasingly popular option. Over the past 15 years, falling prices and increasing efficiency have resulted in a 20% increase in solar energy production; furthermore, as the Sun provides enough radiant energy to Earth each day to power society for year, the potential for solar development is markedly high but requires substantial development (National Geographic 2014). Solar energy production often takes two general forms: for residential power production, the photo-voltaic cell panel (hereafter PV) is the dominant mode; for commercial production, solar energy is converted to thermal energy and harnessed via turbine. Regardless of implementation, the primary obstacles of solar energy adoption are geographic space and high costs; otherwise, solar energy is a remarkably adaptable technology that can be deployed nearly worldwide despite differences in climate (National Geographic 2014). For the purposes of this research report, the focus will revolve around PV

The solar industry has been riding a roller coaster over the past decade. Beginning with stratospheric poly-silicon prices and growing demand, the industry first hit a period of robust governmental subsidies, and market and investor hype. Typically, one might have expected an era of growth and stability to follow. Instead, the industry was beset by the financial crisis, the elimination of feed-in tariffs and other subsidies by governments seeking to marshal resources or avoid defaults during the European debt crisis, cheap natural gas, the much-maligned inexpensive Chinese imports of solar panels, a plummeting price of poly-silicon and a steady drumbeat of bankruptcies seeking to re-set long term

The US government is also actively providing grants under the SunShot initiative to help encourage the widespread adoption of solar energy. Mechanization and factory automation could further reduce the cost of solar panel assembly.

Solar photovoltaic cells are catogorized into three generational groups. First generation cells are made from crystalline silicon, expensive to construct, and offer little flexibility. Second generation cells are made from amorphous (non-crystalline) silicon, cheaper to make than crystalline, offer some flexibility, yet still utilize rare and often toxic materials. Consequently, the maturation of the build process for 1st and 2nd generation

“The sun's light (and all light) contains energy. Usually, when light hits an object the energy turns into heat, like the warmth you feel while sitting in the sun. But when light hits certain materials the energy turns into an electrical current instead, which we can then harness for power” (Alivisatos). The method of transforming light into energy by human means is called PhotoVoltaics. Having this general knowledge, humankind created different devices made of a certain kind of material which could turn the solar power into energy; these devices are called PhotoVoltaics cells or solar cells. With those tiny cells, humans have created (for a much efficient use of this power) a much bigger device called solar panels. Solar panels are

Abstract: The current energy situation with fossil fuels as the main source of the world’s energy has two main flaws: fossil fuels contribute to global warming via the greenhouse effect and they are limited in the quantity that remains. Solar power solves both of these problems and can be captured by utilizing photovoltaic cells. However, photovoltaic cells have their own drawbacks due to their high costs of installation and maintenance.
