1. From your results in Tables 2, 3 and 4- of your lab procedure: a. Plot the power across the 1 K0. resistor for the three solar cells as a function of illumination level for shadow, at and direct sunlight b. Plot the power per square cm of solar cell area across the 1 K9. [or 1009] resistor for the three solar cells as a function of illumination level for shadow, at and direct sunlight c. Plot the power per solar cell dollar across the 1 K11 [or 10011] resistor for the three solar cells as a function of illumination level for shadow, at and direct sunlight Table 2 - Flat Amorphous CIS Monocrystalline Voltage without load 3. 938 V 4. 187 v 6.45 V Current without load 3. 98 MA 34. 02 m A 9. 29 mA Voltage across 1kQ 1 3. 065 V 3. 961 V 5. 89 V 4. Leaving the EB where it is, have one partner use a hand and cover each solar cell in a shadow while you make your measurement. Now, only diffuse sunlight enters the solar cells. Repeat the measurements taken in Step #1 in this new lighting configuration. Record your measurements in Table 3. Table 3 - Shadow Amorphous CIS Monocrystalline Voltage without load 3. 854 V 3. 187 V 4.98 V Current without load 3. 10 m A 3.0 m A 0. 82 MA Voltage across 1kQ 2, 56 V 2. 182 V 1.046 V 5. Have one partner tilt the EB so that the solar cells are facing directly towards the sun, with no shadows falling on it. Repeat the measurements taken in Step #1 in this new lighting configuration. Record your measurements in Table 4.

Get data from the pre-calibrated CIS solar cell on EB#1 from your TA. You will use the current without load measurements in the calibrated cells to later determine the incident solar radiation on the roof during your lab section. Record these values in Table 5.
