Block D group 3

1.Question How does air temperature affect the ectrical output of a PV cell?

2.Hypothesis If a PV cell is measuring solar energy then the air temperature has no effect on the output.

3.Materials
 * lights
 * a handfull of wires
 * thermometer
 * PV Cell
 * electrical socket
 * clear plastic wrap
 * voltmeter
 * masking tape

4.Procedure 1.You will place lights into a cardbored box with a thermometer taped in the box. 2.You will place a PV cell into the box infront of the lights and connect the alligator clips then cover the box with plastic wrap to keep the heat in. 3.You will plug the lights in and watch the meter and record the data every degree it goes up.

5. Results As the air temperature increased, we found that the electrical output of a PV cell decreased.

6.Conclusion Air temperature does have an affect on the electrical output of a PV cell

7. Challenges Thinking about whether or not the experiment was realistic or not was our biggest problem. The air was not as "free" as the air in the atmosphere, it was trapped inside of a confined space and much hotter.
