Block C Group 1

1. Question - How does air temperature affect the electrical output of aPV cell?

2. Hypothesis - If the temperature changes, Then the amount of electrical engery produced wont change.

3. Materials -
 * PV cell
 * Cardboard Box
 * 2 Heat Lamps
 * Thermometer
 * Clear Plastic Warp
 * 2 Alligator Clips
 * Tape
 * Stop Watch
 * Multimeter

4. Procedure-
 * 1) Gather Materials
 * 2) Place Needed Materials in Box
 * 3) Connect Alligator Clamps to Mulitmeter/PV Cell
 * 4) Place Clear Plastic Wrap over Box - Tape Down
 * 5) Turn on the light and Take a Base Voltage Reading
 * 6) Record Voltage Every 2 Degrees Celcius for 20 Minutes

5. Data table Air Temperature to voltage
 * Temperature (Celcius) || Volts ||
 * 25 degrees || 4.55 ||
 * 27 degress || 4.50 ||
 * 29 degress || 4.45 ||
 * 31 degress || 4.40 ||
 * 33 degress || 4.36 ||
 * 35 degress || 4.31 ||
 * 37 degress || 4.26 ||

6. Conclusion
 * The temperature does effect the amount of volts it produces.
 * The amount of volts droped because it was storing the energy.

7.Problems with the lab
 * we should of had sunglasses to view the thermometer and read the temperature
 * use more tape because some heat might have escaped
