1. The problem statement, all variables and given/known data

this is a lab task, i have found out the IV characteristic of the diode,

now they ask me to suggest a procedure to find the constant A, in the equation
I= AT^3 x exp (-E/ kT),
T being the temperature, and I = saturation current

2. Relevant equations

i know how to find ideality factor fron the the IV graph, but can I find 'A' from the IV graph ?
If not, then what other test equipment and procedures do i need to find 'A' ?
Is 'A' related to the intrinsic carrier concentration in any way?

3. The attempt at a solution

its very urgent, so i ll really appreciate a prompt reply.
thanks :)
