In this study, it was aimed to show the effect of frequency of light on current and potential values in a solar cell. According to the research question: ‘How does current and potential values read on a standard solar cell change when the light intensity changes due to the change in frequency?’, an experiment was done by using a standard solar cell, a powerful light source, transparent glass films and Vernier data logger measurement devices. In the experiment, the solar cell is placed in front of the light source and light probe, and ampermeter and voltmeter are connected to it. By covering the surface of the light source with red, orange, yellow, green, blue and purple transparent glass films respectively, the frequency of light is changed. Increase in frequency means increase in energy of photons of light. When the energy of photons increases, their ability to excite electrons from solar cell surface rises as well. As a result, number of electrons passing through the circuit in unit time, which means current, improves. As the internal resistance of the system is constant, potential increases due to the increase in current. Not only current and potential, but also illuminance changes when the frequency changes as the total energy of photons increases light intensity. In the result of the experiment, it is concluded that the current and potential values read on a solar cell is directly proportional with the frequency of light. As the frequency of light is increased from red to purple, the power in the solar cells will increase due to the increase in current and potential values.
