Block C Group 5 Taylor Frost & Jake Gurecky


 * Question:** How Does the Angle of a PV Cell to a Lght Source affect the Electrical Output?


 * Hypothesis:** If the PV cell is angled directly towarded a light source, then the electrical output will be higher.


 * Materials Needed:** -Light Source, multimeter, 2 aligator clips, 3 science books, protracot, PV Cell, meter stick


 * Procedure:** 1) place light on table. 2) Atatch multimeter to PV Cell using aligator clips. 3) Place 3 books on table in fron of light source and measure 35 cm from light bulb and place PV cell there. 4) make sure PV cell is at 0 degres (facing straight up) and turn on light. 5) record output. 6) increse angle of PV cell to 45, then 90, 135 and finally 180 degrees (facing straght down) record all outputs from multimeter at eac degree. 7) make all final data recordings.


 * Graph:** On paper


 * Conclusion:** This did support our hypothesis. A 90 degree angle has more volts then 0, 45, 135, 180 degree angles.This relates to using a real photovolotaic panel at my house because this could charge a pare of batterys for you.


 * Problems:** 1) We could use better protractor so that the angle of the PV cell is more precise to make our data more accurate. 2) We should have included different distances of the PV cell from the light source in our experiment which could have affected our results making them more accurate. 3) One error with our data is that it was hard to get the protractor right next to the PV cell because the aligator clips were in the way, this may have made our angles for which we reccorded voltage not exactly the angle stated in the procedures. This is not all that big of a deal, but as scientists we need to be extremely precise or else the data we find may be somewhat inaccurate.
