Question

PV cell

Saturation current of 1*10^-11

temp = 298K

Assume voltage is kept constant, solar current density is proportional (linerally) solar radiation and determined by 1/2 sine wave from sunrise to sunset, peak solar density current is 0.015 A/cm^2.

Plot current denisty vs time

Plot power density vs time

Answer 1

Given in question that the solar current density is proportional (linerally) solar radiation and determined by 1/2 sine wave from sunrise to sunset. So the plot of current denisty vs time will be 1/2 sine wave.

Also given that voltage is kept constant,

short circuit is not given so we can not find the max value of power density.

So, power density also will praportional to solar radiation, because P=VI, and given that V is constant. so power direct proportional to current.
