Last Monday, we conducted an experiment involving solar cells, also know as photovoltaics, in order to see how the light intensity and voltage output affected each other. Photovoltaics are one of the green energy alternatives we learned about in class.
My partner and I first started off by connecting the necessary cords to NXT adaptor and the computer in order to track the results of each run. We then started off with no light then increased the distance of the light from 0 cm to 18 cm holding it for 30 seconds each time. This measured the intensity and energy of the light, the closer the light the higher the intensity and the farther the light the lower the intensity. We also experimented with a red color filter at 10 cm and and a green filter at 12 cm to see how that effected the output and intensity.
| No Light | 0.106339667 |
| Light at 0 CM | 0.516472 |
| Light at 6 CM | 0.168779 |
| Light at 12 CM | 0.175194 |
| Light at 18 CM | 0.16493 |
| With Color | |
| Light at 10 CM (Red) | 0.222665 |
| Light at 12 CM (Green) | 0.122591 |
I really enjoyed the layout of this blog. By adding in the graphs as a visual aid, it helps your audience process the information added into the table.
