I measured the voltage of the solar cell between the fresnel lens 30 seconds after I shined the light and the results showed that the solar cell produced highest voltage when the distance between Fresnel lens and the 2nd parabolic reflector was greater. With the presence of Fresnel lens, the light rays were able to concentrate into the solar cell, demonstrating higher efficiency. The voltage produced increased as the distance between reflector and the lens increased. The rapid increase in the trend of the graph show great impact of Fresnel lens in voltage production of solar cells.
