Temperature exponent for series resistance in solar cell in simulink

Dear friends,

I want to use the solar cell element in SIMULINK but there is a problem. I cannot put my temperature coeeficient for voltage which affects the series resistance in solar cell. In the link below, the parameters of the solar cell which have been used in SIMULINK element are available.

http://www.mathworks.co.uk/help/phys...solarcell.html My question is that :

How the two exponent coefficients for series and shunt resistance (TRS1 and TRP1) can be calculated or measured. I don't know how to get these data from my solar cell.

Is there any relation between temperature coefficient voltage and temperature exponent for series resistance?

Could any body help me with this issue?

Kind regards, Hamed

I have exactly same problem.

i want to study about my PV module and find out about the effect of shading on its cells. but i can not find anything about voltage temperature coeeficient in simulink solar cell. I also don't know, how can i calculate two exponent TRS1 and TRP1.

could anybody help me?

Best regards.
