hi,
how can i make a spice model for this cell?


Hello Heitham,

I have uploaded an example with your solar cell.

Best regards,

thank you Helmut for the answer,just two more question : why in I=V(VLUX)*50u you have 50u? and how did you know R2=5?

Hello Heitham,

I=V(VLUX)*50u you have 50u? and how did you know R2=5?
It's just a wild guess. Your datasheet contains too less
information. You may have to do a measurement on the next
sunny day to get better data. One cannot make a precise model
from nearly zero information.

Maybe you should better use 45uA and 4 Ohm.

Best regards,
Helmut
