Solar Energy Lab

The goal of solar experiment was to see how lights on different distances and with different colors affects voltage on a solar cell.

For this experiment we have been given the solar cell, which we plagued in to the battery and to the computer, five filters of different colors and a flashlight. By clicking start on the computer, our experiment began and we were supposed to light the solar cell. First five trials were without any filters, but the distances of lighting were changed every time. We used the ruler to measure it. For the next five trials, we used five different colors, but the distance stayed the same.

After every trial the computer implemented calculations of the voltage. All we had to do is to sum the last ten and then we had an actual number for the specific trial.

When all the trials have been finished, by using excel, we were able to make diagrams based on our results.

That leads us to the conclusion that the bigger the distance, the lower the voltage. Also, colors have an impact on lights intensity, because there is diverse voltage for every color.
