Due to the rapid development of science and technology, the need for energy is increasing all over the world. Therefore, the demand for natural clean energy is increasing. The way to meet the demand for energy is the extensive use of renewable energy sources. It is best to use solar energy. In the production of solar cells, of course, it is important to fully determine the photovoltaic properties of the materials from which they are made. Almost all solar cells manufactured today are silicon-based solar cells. When preparing solar cells, it is better to first develop their model and then proceed to its production. For this reason, we calculate the physical processes that take place in silicon through the C# programming language, and then implement them in practice. The possibilities of this program are very large, unlike other programs, the possibility of using the technique is wide. That's why we use C# programming language widely. The quantity that we are currently determining is to determine the forbidden area of ​​the silicon element as a function of the external temperature. First of all, we will show how the bandgap width for silicon depends on the temperature

Eg=1.174 - (0.000473*T^2)/(T+636) (eV)

• The above formula expresses the temperature dependence of the forbidden band width for silicon. Based on this, we studied and analyzed the temperature dependence of the forbidden band width of silicon in the range from 0 to 60 using the C# programming language. Accordingly, it was focused on determining the variables based on the program. In the C# programming language, we introduce variables and constants for specific quantities.The algorithm for determining the forbidden area width for a silicon element in the C# programming language is as follows.

double E, T, T1, T2, b, c;

• double E, T, T1, T2, b, c;
• int a;
• a = 636; b = 1.174; c = 0.000473;
• Console.Write("T1=");
• T1 = double.Parse(Console.ReadLine());
• Console.Write("T2=");
• T2 = double.Parse(Console.ReadLine());
• { for (T = T1; T <= T2; T++)
• {E = b - (c * Math.Pow(T, 2)) / (T + a);
• Console.WriteLine("E=" + E); }}
• Console.ReadLine();

The C# programming language is widely used in the field of technology and science. I have compiled and calculated the algorithm of my thesis using the C# program. The algorithm for determining the forbidden area width for a silicon element in the programming language is as follows.

In this algorithm, the symbol "T" stands for temperature and its value is given to change from temperature "T1" to temperature "T2". Based on the formula given above, the value was determined in the order of increasing temperature from 0C to 60C.

• In this algorithm, the symbol "T" stands for temperature and its value is given to change from temperature "T1" to temperature "T2". Based on the formula given above, the value was determined in the order of increasing temperature from 0C to 60C.

The values ​​obtained from the program give the analytical result as follows. Each of the obtained values ​​for the forbidden area width corresponds to the values ​​from 0C to 1C. However, the value set as the maximum limit corresponds to the forbidden area width value of 60C. So this graph can be obtained. As a result of these studies, it was found that the graph corresponds to a 97% linear function. Therefore, we can say that the width of the forbidden zone changes linearly.
