Solar Power
The purpose of our project was to determine the electrical output of a photovoltaic cell when several factors were varied. Through research we decided on the following variables: the illuminance of the light source upon the cell (as determined by the distance between the source and the cell), the presence of a magnifying glass to focus the light upon the cell, and the wavelength of the light. As logic would suggest, we found that the electrical output in both volts and amps was maximized when the illuminance of the light source was greatest and the magnifying glass was present to focus the light. Surprisingly, the relatively low-energy "yellow" light produced the best results. Although it was not definitively determined by our experimentation, our data suggested a relationship between the change in voltage and amperage when certain factors were varied.
