Comments on Effect of Light Intensity

Comments

Please state the reason of decreasing or increasing with intensity of light?

Would be nice if the expression had all the terms defined. A similar comment could be made everywhere on this site. Undergraduates would spend too much time trying to determine "what is n?" In this instance.

What is the Voc ?
- It is the Voc at standard irradiance and standard temperature ? (1000W/m², 300°K)
- It is the Voc at the current temperature ?

I'm searching the formula to obtain :
Voc = fct(irradiance, temperature).

I know some characteristics of my solar panel (Voc variation with T when X is fixed, Voc variation vs X when T is fixed).
