Where can I find a good free software to calculate the efficiency of shunt resistance series resistance from power output curve? I have the I-V data of chalcogenide thin films
Dear Binod,
shunt resistance (Rsh) related with device (you can find it from dark current), and series resistance (Rs) related with light current.
Rs and Rsh can be calculated from the slope near from Vm (maximum voltage) and Isc (short circuit current), respectively.
where Rs =dalta V/dalta I=1/slope near from Vm
Rsh= dalta V/dalta I=1/slope near from Isc
you find the slope from the data of I-V characterization.
with my best wishes
It can be find with the help of v_ I characteristics.
