1.Question 1

What creates the potential difference (voltage) in a solar cell?

The absorbed photons

The bonds between the silicon atoms

The pn-junction

The outside circuit

Correct

That is correct

1 / 1 point

2.Question 2

Select the correct statement(s)

Photons absorbed in the n-type layer outside the space charge region do not contribute to the photo current

Photons absorbed in the p-type layer outside the space charge region do not contribute to the photo current

Photons absorbed inside the space charge region contribute to the photo current

Correct

That is correct

Photons absorbed in the space charge region will contribute to the photo current.

1 / 1 point

3.Question 3

Which direction will the electron move given the indicated electric field?

Left (towards the n-type)

Right (towards the p-type)

Correct

That is correct

The electron will move in the opposite direction of the field.
