Abstract
Our project aims to study a different combination of solar cells (photo-voltage) and trying to produce a samples of it contains more than a type of materials.
The properties we want to catch is a combinations which ensure a good efficiency and have the ability to absorb the largest amount of sunlight to turn it into a voltage of the appropriate amount.
The project contains the principle of experimenting with more than one installation method and more than one model so that each model has a certain material and a different installation method to apply the sun projection experiment on each model and study the efficiency of the voltages that we can reach in each model, taking into account the (optimum tilt angle) mechanisms that achieve the best angle Dropping of the rays located on the cell surface.
On the other hand we are trying to focus our attention on the effect of the rise in the external temperature of the solar cell and the adverse effect obtained on its efficiency . and for achieve that we decided to use a miniature solar cell model of 10W of power , and we'll test it under certain condition then monitor its efficiency as its temperature rise . After that we will work on three different models so that each model has a different idea but the same principle is the principle of using repeated water movement inside the pipes and used it for cooling the cell .
We have divided the three models into the following :
• The first is to add a network of water pipes in the back of the solar cell to pass cold water from them (heat extraction with fluid circulation) .
• The second model focuses on the idea of adding small pumps of water on the outside of the cell (glass) so that it pumps water on the surface of the cell every period of time, which also helps to get rid of the dust accumulated on the surface of the cell, which reduces its efficiency as well .
• The third model is simply the process of merging the two previous models together .
After applying the previous models we will measure the efficiency of each of the models under the same basic weather conditions and compare them together to know the best way to cool the cell and get the continuity of its efficiency, which ensures its work properly and produce energy as it should
