Below you see a plot of an ideal and a non-ideal JV curve. Based on this plot and assuming an irradiance of 1000W/m2, give approximately the numerical values to the questions bellow:

Question

I. Estimate the ideal Fill Factor (in %):

II. Estimate the non-ideal Fill Factor (in %):

III. Estimate the ideal efficiency (in %):

IV. Estimate the non-ideal efficiency (in %):

V. Which of the following statements is TRUE?

The inverse of the slope of the non-ideal curve at V=Vocis approximately equal to the shunt resistance.

An increase in shunt resistance will result in an decrease in fill factor in reference to the non-ideal case.

A large current in the shunt branch will increase the efficiency of the solar cell

The inverse of the slope of the non-ideal curve at V=Vocis approximately equal to the series resistance.

Answer 1

81.63
65.306
15
12

The inverse of the slope of the non-ideal curve at V=Vocis approximately equal to the series resistance.

Answer 2

1=81.63
2-=65.31
3=15
4=12

Answer 3

1)81.63
2)65.31
3)15
4)12

Answer 4

The inverse of the slope of the non-ideal curve at V=Vocis approximately equal to the series resistance.
