The Degradation Of Solar Cell

After becoming familiar with the topic we had to create a program. Part of the code again was provided but we had to modify it in order to obtain the specific output instructed. I have to tell you this time I had some questions and frustrations writing the code,

Our intention of this project is to create and deliver a working prototype for our clients as a possible solution to the problem. Guidance and demonstration will be provided to the client for

1. Use of phase gate model and project management tools same as traditional. On top of this, the Primavera software was used for the scheduling of the project.l

Purpose: The purpose of this paper is to give you an opportunity to apply and demonstrate your understanding of the tools and principles covered in the class to a project of your choice.

In this project, I am looking forward to solve a possible problem of my client as part of my A-Level Course.

Introduction: The tradition solar cells have many faults and are dangerous to the environment. The TSC gives out a lot of pollution through its waste such as silicon tetrachloride. Also, when the reactors need to be cleaned several harmful greenhouse gases are used. The eye sensitized solar cells that are being designed in this lab are much cleaner for the environment. No waste is produced and no harmful gases are need to clean them.

There are many organizations that work for this project. The following are some of the organizations that author will describe in this paper.

Over time plants have come up with possibly the most proficient power supply in the world. This power supply is known as photosynthesis. This is the transfer of sunlight, carbon dioxide and water into utilizable power, giving off oxygen along the way. When it comes to plants, usable fuel comes in the form of proteins, fats and carbohydrates. People, alternatively, are looking for liquid power in order to run things like cars and refrigerators. Scientists believe that trying to artificially recreate photosynthesis can be a way to solve the expensive and dwindling energy issues that society faces today (Layton, 2012).

Subsequently, the next box is “none of these words.” This box must be combined with another one of the boxes above as it is meant to pick out the words typed in and exclude any resources that mention those words. Functioning as a Boolean “not.” In order to use this box to narrow the number of results, pick a term that is not relevant to what is being researched, but related to the topic. For the example search, if “wind,” “nuclear,” and “coal” are typed into the “none of these words” text box the search will be more focused on solar energy instead of other sources of renewable energy. An example that reflects the change made with the search is the “Solar Industry Data” the article tracks trends and growth related to solar energy, and is

Solar cells are categorized into three major generations , First generation solar cells are based on silicon wafers and have an efficiency of 15-20%, The major advantage of first generation solar cells is their stability ,However due to heavier production costs ,large amount of energy is involved during their production that makes their large scale production uneconomic and unaffordable .

2.1     The first practical solar cell was developed at Bell Laboratories in 1954. With the advent of the space program, Photovoltaic cells made from semi-conductor grade silicon quickly became the power source of choice for use on satellites. The systems were very reliable, and cost was of little concern. In the early 1970s, the disruption of oil supplies to the industrialized world led to serious consideration of Photovoltaic as a terrestrial power source. This application focused research attention on improving performance, lowering costs and increasing reliability.

A Silicon solar PV Cell is a device which is made up of semiconductor materials that produce electricity when exposed to light energy. [1] The doping process of a Silicon based PV Cell works by the photovoltaic material converting the light energy, photons, it absorbs into electrical energy. [1]

After that day we started our research on this project from 22 February, 2012. We got our honorable faculty as our advisor and also as our mentor.

The satisfaction and euphoria that accompany the successful completion of any task would be incomplete without the mentioning of the people whose constant guidance and encouragement made it possible. We take pleasure in presenting before you, our project, which is result of studied blend of both research and knowledge.
