2.Question 2

Do you want high or low values for the series and shunt resistance respectively for optimum solar cell performance?

Low shunt and high series

Low shunt and low series

High shunt and low series

High shunt and high series

Correct

3.Question 3

The following IV curve has been recorded for a solar cell. The short circuit current is 40 mA and the open circuit voltage voltage is 0.7V.

What can we infer about the internal parameters from the IV curve?

Notice that RS is the series resistance, and RSH is the shunt resistance.

High RS and low RSH

High RS and high RSH

Low RS and high RSH

Low RS and low RSH

Correct

That is correct

You can read more about parasitic resistances here. You can also revisit the series and shunt resistance virtual instrument.
