Solar Energy Lab

Part 1:
To start the experiment, we recorded the minimum voltage with no light coming on the solar cell.
We exposed a solar cell to a light coming from a flashlight at different distances, first against the solar cell ( to get the maximum voltage ), then we put back the flashlight at 10 cm of the cell, and finally at 20 cm.
We recorded the average of the voltages for each case on a excel data sheet. Then we drew the corresponding graph.

Conclusion:
The closer is the light, the higher is the voltage.

Part 2:
In the second part of the experiment, we have almost done the same thing. In this part we used three color filters (red, yellow, green) just in front of the solar cell. We recorded the average voltage with no filter, and then with the three other filters.
Here is the graph we have got so far:

Conclusion:
We get more voltage when there is no color filter.
