The in-class solar cell experiment we went through was one that examined and allowed us to understand the amount of voltage created in relation to the intensity of light. In other words, we were discovering how much energy was created/transferred through light and differing distances. We also were experimenting with how different wavelengths (colors) of light affected the voltage created/transferred.

When we were experimenting with the different distances, we first began holding the light directly onto the solar cell for 30 sec. and averaging the voltage received by the solar cell. In the following four trials, we held the light 2, 4, 6, and 8cm away from the solar cell to observe the difference in light intensity in relation to voltage received by the solar cell.

We then began experimenting with the different wavelengths of light and how the affected the voltage received by the solar cell. For these four trials we held the light directly onto the solar cell; however, we had a transparent sheet of colored plastic between the light and the solar cell to change the wavelength of the light being absorbed by the solar cell.
