The purpose of this lab was to be able to understand how the relationship between light intensity and voltage output works, as well as the relationship between the wavelength of light and the voltage output of the solar cell. We performed many experiments to try to gain an understanding of this, shown below.
For filters, the frequency of blue light is higher than red, so more volts were produced under the more transparent, blue light.
For the red filters, the output of voltage were .282119(V) for light red #26, and .3057V for medium salmon pink, #32 .
The blue filters, medium violet #359 , and mist blue #61, had voltage output average of .3638V, and .3732V respectively.
| Light Type/Info | Average Voltage Produced (v) | |
| RED | Light red / #26 | 0.2821 |
| Medium Salmon Pink/ #32 | 0.3057 | |
| BLUE | Medium Violet/ #359 | 0.3638 |
| Mist Blue/ #61 | 0.3732 |
Voltage vs Intensity:
High intensity: .358663 voltage output, 97.23 light intensity
Med intensity: .3264 output, 94.4 light intensity
Low intensity: .2987 output, 88.06 light intensity

The graph and chart above show that there is more energy reaching the solar cell, which means more voltage is the result. If there is a higher amount of voltage, then there is also a higher intensity level, which is demonstrated above.
