Answer:

[tex]Isc -I = Io [e^{\frac{qv}{nKt}} - 1][/tex]  

Explanation:

the equation of current for the diode is

[tex]I = Isc - Io [e^{\frac{qv}{nKt}} - 1][/tex]     ..........................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 ×[tex]10^{-23}[/tex] 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

[tex]Isc -I = Io [e^{\frac{qv}{nKt}} - 1][/tex]  

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
