In class, we connected a small solar cell to the NXT adaptor and measured the cell's acquired voltage with a probe. To do this, we placed a small flashlight from varying distances and aligned the data acquired by the NXT adaptor with the different distances measured. The chart below exhibits that the voltages acquired by the solar cell gradually decreases as the flashlight is distanced further away.
Next, we placed four different colored film filters in order to see how different light spectrums affected the acquired voltage of the solar cell. The light was placed directly against the solar panel with each respective film sheet in between them. The chart below shows that the darkest hue, blue, limited the voltage the most. Whereas the lightest hue, pink, emitted the most light and gave the cell the most voltage.
