In the solar cell lab we looked at the measuring the correlation of voltage difference between the front and back of a solar cell. We took a ruler at and measured the voltage produced on LabView software at various distances; first starting with zero distance. The light intensity by defintion is the measure of energy of light and voltage is the amount of energy per charge required to move the charge around a circuit. The higher the intensity, the more photons that are generated which equals greater current flow and voltage. We found that this was conclusive in our experiement because the further away we measured the light from the solar cell, the lower the voltage was and the less intense the light was as well.We also put different colors of film across the solar cell light (blue, pink, and teal) with no distance away from the solar cell to see how the light intensity would be affected there as well. Pink had the highest light intensity with blue and finally teal following. Our results are showcased in the following Excel spreadsheet along with corresponding charts and bar graphs:
I found the house wit the solar panel on the roof very unique. It blended in with the house. Lverall, the post was very insightful and anyone can learn a lot about solar energy.
I really like the two diagram pictures in this post. The display’s showing the science behind what we’re testing are extremely beneficial to someone who has never done this experiment. The more information and visual aids, in addition to the the elaborate procedure, significantly contribute to understanding the science of the tests. Both are a great addition to the detailed procedure of the experiment.
The introduction of the diagrams into the beginning of the post was a great way to slowly ease the audience into the actual beginning of the post. The description of the actual experiment gave a credibility that is enhanced with the excel sheet of your results, allowing to the reader to physically see exactly what the results meant, in comparison to each other.
