Nanotechnology, with its unprecedented control over the structure of materials, can manufacture efficient and inexpensive solar cells on large scale. Nanotechnology is producing some significant advantages in solar cells to increase the efficiency/cost ratio by using nanomaterials with suitable bandgaps (Zweibel 2000). Nanomaterials enhance the effective optical path and significantly decrease the probability of charge recombination. Nano-structured CDs as a window layer, CdTe as an absorber layer and TiO2 electrodes are of interest as in thin film solar cells.
The quest for alternative fuels has become one of science’s major pre-occupations and finding ways cost-effectively produce energy from the sun is a key battlefront. The usage of solar cells results in many useful features like require less maintenance effort, avoid the release of toxic gases or other noises and mainly avoid transmission losses and costs.
Also, the solar cells available today are not considered feasible when compared to the non-renewable sources.1 The solar cells manufactured at present are low in efficiency and very expensive if they have to be used to generate electricity on a large scale. We are interested in using the valuable features of nanotechnology so that we can manufacture efficient and cheaper solar cells in large quantities. ...Download file to see next pagesRead More

Advantages of using solar cells

...? 23 July Advantages of Using Solar Cells The environment has become a big issue around the whole world. During the last decade, it started to change quickly. The earth is becoming warmer and because of that, there are a lot of natural problems and disasters around the world. This is called global warming. People on earth caused this change in temperature. Further, people need energy in their daily lives. They need electricity, fire, hot water, heating and cooling. To produce energy that is enough for all of these activities, we need fossil fuels and coal. All the countries around the world use these two fuels to make electricity and to heat water or air. Many rich countries depend on countries in the...

How solar cells are made

...Solar Panels: Harnessing Renewable Sources of Energy The importance of using renewable sources of energy such as solar energy is a crucial issuenowadays. There are two main reasons for such 1) renewable sources are free 2) use of such type of energy does not contribute to greenhouse gas emissions as compared to fossil fuels. In Britain alone, use of solar energy is aggressively promoted by the government due to high incidence of “fuel poverty”. There are many types of solar technology that can be used depending on the needs of the consumers. However, this paper is focused on Solar Photovolatic technology commonly known as “solar...

Solar cells

...Solar cells Introduction Energy crisis is going to be the biggest problem people all over the world may face in future. Increased use of automobiles and the huge development of industries are causing big demand for energy. Scientific principles or the energy conservation theory say that the total amount of energy in this universe remains a constant. Moreover, energy can neither be created and nor be destroyed even though it is possible to convert energy from one form to another. It is assumed that the total oil energy sources available in this world are sufficient enough to meet the energy demands only for thirty or forty years more. Most of the energy sources we are using at present are nonrenewable in nature. Fossil fuel energy... ...

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...

Organic Solar cells

...14 March Organic Solar Cells Introduction Organic solar cells are devices that produce electri from sunlight through conductive polymers, which are forms of organic molecules. The technology is just gaining acceptance because of its cost implications. Organic polymers are relatively cheap and easy to access; they also posses many physical and chemical properties that allow them to be used in such applications. However, they have certain shortcomings that may limit widespread adoption. History and background of organic solar cells As far back as 1839, a physicist named Edmond Becquerel discovered the photovoltaic effect....

...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. Structure and Working of Solar Cells The...

Nitrogen-Containing Carbon Nanotubes for Solar Cells

...by mild chemical doping. To alter their molecular structure, highly reactive chemicals are needed. Sulfuric acid is one good example of that strong chemical. Phosporic acid when heated is another. Nitrogen when heated was also found to have an impact on CNTs. Radicals like peroxides (e.g. benzoyl peroxide or potassium persulfate) can transform CNTs into very soluble matter. Sample studies about these are mentioned in this paper. Synthesis Three CNT-based film structures dominated the interest of scientists in 2011 insofar as solar cells applications are concerned. These are (a) CNT graphene layers, (b) CNT amorphous films, and (c) the CNT diamond-like films. They found that adding...
