Objective: The objective of this lab was to show the way light intensity is seen with a solar cell. The point of the lab was to show us the relationship between light intensity and the voltage output.
Step 1: We started the lab by having no light on the solar cell and the average my group came up with was .12.
Step 2: We then added light with a flashlight and we shined it on the solar cell for a certain amount of time. The average that we came up with was .33172.
Step 3: Then we moved the flashlight back to see if we would get a different result. We did this from different distances to see if we would get other averages. First we had the flashlight 4 inches away from the solar cell and got an average .115943. We moved it back 4 more inches, 8 inches, and the average we got was .118742. We moved the flashlight back 4 more inches, 12 inches, and we came up with .03663 as the average.
Results:
The next graph shows how we used color filters on the solar cell (green, black, and blue). We also included no filter in this graph as well.
