Write the equation of current for the diode (i. e. solar cell) in the light. compare it with diode current in dark ?

Explanation:

the equation of current for the diode is

    ..........................1

here Isc is short circuit current

Io is the reverse saturation or the dark current

I  is load current

q is charge

K is Boltzman constant i.e 1.381 × J/K

n is ideality factor

T is absolute temperature

and

here Isc - I is net current flow through diode and actual current when it is in light

so

here we know Io is dark saturated current it mean in the absence of light diode leak current density

and Io is important parameter to differentiate between diode

energy can cross the boundaries of a closed system in the form of heat and mass
