Abstract: Organic solar cells (OSC) represent a young photovoltaic technology that uses organic semiconductor materials to convert sunlight into electricity. These materials can be deposited at low temperatures in a continuous process on flexible substrates, enabling a very high throughput. As a consequence the production costs are dominated by the material costs. The technology used for the manufacture of solar cells is predominantly silicon based an inorganic material. The semiconductor industry developed a deep understanding of the properties of this material, allowing for an easy transfer for use in the solar cell as a solar cell practically mimics the operation of a semiconductor wafer, in that it allows for the transport of an electric current. In this paper a program is written in C++ to estimate the solar radiation in different areas and calculate the total power which can be generated through the solar energy. It also calculates the angle at which the solar panel is fixed to trap maximum solar radiation. Then a fuzzy logic based C++ program is written to track the solar panel by sensing the voltage and temperature of the panel. For computing the solar radiation different inputs such as monthly average global radiation, regression constant, extraterrestrial solar radiation, declination angle, latitude angle etc. were noted. When these inputs are given to the written program then it will automatically give the total possible energy production through the solar radiation. We use organic solar cells has low production costs in high volumes. Combined with the flexibility of organic molecules, organic solar cells are potentially cost-effective for photovoltaic applications. Thus, it costs approximately five times as much for electricity from solar cells. If the cost of producing solar cells could be reduced by a factor of 10, solar energy would be not only environmentally favorable, but also economically favorable.
