Extract of sample "Solar Power: Photovoltaic Cells"

Download file to see previous pages The practical use of solar cells, however, was made possible in the 1950s with the discovery of silicon’s ability to generate electric current on exposure to light. The first usable silicon solar cells had an efficiency of six percent but the percentage today is much higher at about 20 percent. Solar power usage is also on the increase with more people turning to solar power as a source for their energy needs both in their homes and at their businesses and the technology is also being utilized in large scale by utility companies. The typical small-scale solar panels used domestically are made of solar cells clustered into modules that can accommodate up to 40 cells. The solar cell contains semiconductors which in turn contain weakly bonded electrons in their valence bands (Luque and Hegedus, 2005). These valence bonds break on the application of bandgap energy on the valence electrons, therefore, releasing the electrons to move to the conduction band. Electrons moving in the conduction band enable the material to conduct electricity. The distance separating the conduction band and the valence can be measured and is represented in electron volts (eV). The particle of light, better known as photons can provide the energy required to free the electrons (band gap energy). On exposure to sunlight, the electrons within a solar cell get hit by photons and on absorbing the energy they move to the conduction band where they are collected and driven to an external circuit (Luque and Hegedus, 2005). These electrons will lose their energy by driving machines such as water pumps, fans, sewing machines, a light bulb, mentioning but a few. ...Download file to see next pagesRead More

Solar Energy Power (Photovoltaic Systems)

The paper tells that solar energy has been the most dominant energy source since the dawn of civilization, though indirectly. But with the rise of industries and heavy machinery, solar energy has lost its importance and the use of fossil fuels has become commonplace. But as early as the 1970s, there have been researchers enjoining governments to find alternative energy sources. For example, in 1971 Farrington Daniels said: As [coil, oil and gas] diminish, atomic and solar energy will eventually become important: atomic energy in large multi-million-dollar installations near large cities and in areas where solar radiation is low, and solar energy in small inexpensive units n rural areas where solar radiation is abundant and the cos...

...? Photovoltaic Cells Solar energy, being a renewable source of energy, is a boon for those who live in isolated locations, particularly where grid power cannot reach. Van Geet home is an off-grid house that has received a special attention for its energy saving designs. Photovoltaic Cell is a heart of energy systems producing energy from sun. PV cells alone constitute almost 50 percent of the total cost of such energy system; therefore, all research is directed toward the reduction of its production cost. Though it is still a costly technology yet its cost per watt has reduced considerably in last few years. PV cells energy conversion efficiency has now crossed mark of 20 percent. Several companies, universities and research institutions...

Photovoltaic Solar Cells: Alternate Energy Sources for Electricity Generation

...Photovoltaic Solar Cells: Alternate Energy Sources for Electricity Generation Abundance of free and seemingly infinite quantity of sunlight available to the earth is a resource of energy, which has remained relatively untapped. Harnessing of this energy for conversion to electricity by photovoltaic technology is of recent origin and offers considerable potential for its commercial exploitation in the years to come, amidst dwindling resources of fossilized fuels. It has emerged as a major power source, because of its proven reliability and several economic and environmental benefits. solardirect.com suggests the factors of reliability which support its cause as given below: It is free, clean and permits storage for use, when needed.

Solar cells

Most of the energy sources we are using at present are nonrenewable in nature.
Fossil fuel energy and nuclear energy are the popular energy sources at present; however, these energy sources are not only getting exhausted but also causing problems to the environment. Moreover these energy sources are non-renewable in nature. On the other hand, solar energy is a renewable energy source. But the technologies available to exploit solar energy is not developed properly yet. Whatever the solar energy exploitation technologies available now are expensive compared to the other energy sources and hence still we are relying on conventional energy sources such as coal, fossil fuel, nuclear energy etc. However, solar energy seems to be th...

Organic solar cells

...Organic Solar Cells Organic solar cells are a kind of polymer solar cell. Organic solar cells use organic electronics for absorption of light and transport of charge to use the photovoltaic effect to generate electricity from the sunlight. The production cost of plastic employed in the organic solar cells in high volumes is low. Owing to the high optical absorption coefficient of the organic molecules, a small amount of materials can result in the absorption of light in large amount. One of the major disadvantages of the organic solar cells is their low efficiency. Other disadvantages include low strength and stability in comparison to the inorganic photovoltaic cells. Solar energy is a potential alternative to the production of energy...

... still recombine and lose relevance. Finally, those that do not combine can be collected at the electrodes of the cell and used to power man’s activities. Figure 2: The organic solar cell photovoltaic process Source: (Nalwa 5) From the above illustration, optical losses can occur due to two primary reasons; the loss of unabsorbed light that leaks out from the organic cells as well as reflection that occurs at the surface. It has been found that the best solution to this problem is to increase the thickness of the layers in the cell. Texturing the top surface can reduce losses due to reflection and application of an antireflection coating. It is necessary to have concentrators as this also reduces the amount of photons that leak out...
