Abstract
In this study, it was aimed to show the effect of light intensity on voltage produced by the solar cell. According to the research question: ‘How does voltage produced by the solar cell change when the light intensity changes?’, an experiment was done by using a light source, standard solar cell, transformator, light meter and voltmeter. In the experiment, the solar cell is placed under the light source and voltmeter is connected to it. Light meter is placed near the solar cell to measure the light intensity. Light source is connected to the transformator and intensity of the light source is changed by using the transformator. Voltage and intensity of the light values are measured in each intensity. Increase in intensity of light means increase in number of photons. Thus the total energy of the photons increase and more electrons are emitted from the solar cell. After all, potential of the cell increases. In the result of the experiment, it is found out that there is a logarithmic relation between light intensity and the voltage produced. After an intensity value, increasing rate of voltage decreases due to the characteristic property of the solar cell. Also, it is found out that light intensity is directly proportional to the fifth power of the voltage. As the intensity of light increased, the power in the solar cell will increase due to the increase in voltage.
