1.Question 1

Label the IV curve

The above IV curve is shown with the following parameters: Voc, Isc, Vmpp, Impp, and MPP.

Which label is associated with D?

Voc (open circuit voltage)

Isc (short circuit current)

Vmpp (maxumum powerpoint voltage)

Impp, (maximum powerpoint current)

MPP (maximum power point)

Correct

That is correct

1 / 1 point

2.Question 2

Label the IV curve

The above IV curve is shown with the following parameters: Voc, Isc, Vmpp, Impp, and MPP.

Which label is associated with A?

Voc (open circuit voltage)

Isc (short circuit current)

Vmpp (maxumum powerpoint voltage)

Impp, (maximum powerpoint current)

MPP (maximum power point)

Correct

That is correct

1 / 1 point

3.Question 3

Select the correct statement(s)

The fill factor is the ratio of the used to unused area in a solar module

The power of a solar cell is the product of VOC and ISC

The ISC is always the maximum current the solar cell can produce

Correct

That is correct

The short circuit current is by definition always the maximum current. If a solar cell had a fill factor of 100% the current at the maximum power point would equal the ISC, however a fill factor of 100% is not physically possible.

1 / 1 point

4.Question 4

Calculate the efficiency of a solar module with the given parameters:

• FF = 59%
• VOC = 5.5 V
• ISC = 37 mA
• Area = 15 cm2
• Illumination 1000 W/m2

Please provide the answer in percentage (%), do not write the % sign (example answer 8.5).

0 / 1 point

5.Question 5

Select the correct statement(s)

The circuits in (a) and (b) are identical

Correct

That is correct

There is no difference between the circuits, both the voltmeter and the ampmeter are connected in parallel to the solar cell.

The setup in (a) allows for the measurement of VOC

The setup in (a) allows for the measurement of ISC

Correct

That is correct

An ideal ampmeter has zero resistance, while an ideal voltmeter has infinite resistance.
